what your paladins main says about you
a comprehensive essay by a paladins player of right around 4 years
this is like really long so iâll make it under the cut so my followers donât have to scroll through this if they donât wanna
(for context iâm a current maeve main, i used to main skye and sha lin and played tyra a long while ago)
.
Androxus
itâs not a phase, mum
âi donât care we donât have healer, iâm really good at him i swearâ
you ult every time it loads in and you die before the final shot
your favorite mode is siege because you can fly up and shoot the whole point on ult
youâre usually really stand-offish and donât communicate much and/or a 13 year old boy with anger issues
.
Ash
you are level-headed but in a scary way
you will hold the point solo even if it costs you your streak
âget on the pointâ âguys get on the pointâ âattack the objectiveâ
youâll ult to save yourself 99% of the time
good leader
.
Atlas
you probably used to main lex or androxus before he came out
âheâs like a flank, but a tank, heâs great!â
you chase after solo kills instead of sticking to the point
healers hate you, flanks and damages fear you
your favorite mode is death match
.
Barik
youâre a former/current tf2 player looking for something fresh
you donât like working too hard so you spam turrets on the point and hope for the best
âhealer stick to me iâm boutta ultâ
actually really nice between rounds
but you donât communicate much mid-game and kind of do your thing
.
Bomb King
youâre a really old player. you have the beta makoa skin and you were there when lex was first released. veteranâs discount.
your favorite maps are the old ones and they barely show up any more
the team always underestimates you
âwho plays bomb king in 2021 lol?â
you need a hug
.
Buck
âwait, heâs a flank? i thought he was a tank??â
youâre also a veteran in the game
youâre a dying breed. i like never see you. do you even exist?
youâve been here since like the first day of the game
buck gets so many skins and you want all of them but the best you have is a random recolor
.
Cassie
sweetest person alive
âwe can do it guys! letâs try to all rush the point this time!â
you are the bane of every flank
the opposing team hates you, your own team kind of doesnât notice youâre there
*casually gets a pentakill*
.
Corvus
you know those weirdly political kids who like ww2 and know the details of every tank to ever exist? yeah thatâs you
but like thatâs corvus. as a character.
but no one ever plays him.
like i never even see him do you exist???
you are a cryptid.
.
Dredge
yo ho youâre a hoe
no seriously the other team views you and they FEAR you
âyeah i just got a penta killâ âYOU WHAT?â âeyes on the point mate donât get distractedâ
hella good at the game and hella casual about it
you like onslaught on the one sea map the most
.
Drogoz
another veteran, are we?
youâre either useless or can wipe out a whole team in seconds. there is no in-between.
you always have a really cool skin.
dovahkiin, dovahkiin...
âi donât care about the point i gotta get them tripsâ
.
Evie
you bought her because you thought she was cute, admit it
*turns into ice right before dying*Â *turns into ice right before dying*Â *turns into ice right be
your personality type is identical to her. no question about that.
always buys faster reload and better speed
strangely good communication with the team
.
Fernando
gay gay homosexual gay
âheâs kinda hot if you look at him the right wayâ
fernando is the tank for gay people
you are gay people
i donât have much more to say
.
Furia
mum energy. not as much as inara mains, but still, mum energy.
will protect every member of the team with your life, even the flanks
youâve been maining her since she was first added
i bet you didnât even know sheâs canonically serisâ sister
âweâve literally failed to capture the point the last 3 times we might as well give up and go to another gameâ
.
Grohk
âyeah i have a gremlincore tumblr blog, how could you tell?â
i honestly have no words
youâre kind of like a catboy but a racoon
do you even heal the team or do you just pretend
you were there when lex got announced and thought he was cringe, now everyone finally agrees with you
.
Grover
he was your first purchased character and heâs stuck around ever since
heâs the only healer you can play well
âi am groot lmaoâ
you would never say a word to your team
would give your life for the tank but thatâs about it
.
Imani
daenerys targaryen on drugs
your favorite anime is my hero academia
your husbando is todoroki
you see where i am going with this
âteam protect me iâm gonna ultâ *dies 5 seconds into ult*
.
Inara
BIG MUM ENERGY
your team is your family. you will protect them with your life.
can only hold your own with a good healer so you have good teamwork going for you
*cutely places wall in front of your ult*
useless in tdm so you stick to onslaught, siege and koth
.
Io
are you a furry, furry, or a furry?
âvictow! dont ult on my tweam pwease! uwu!â
you 100% find her attractive in some way shape or form
you are either a 30 year old redditor who enjoys loli content or a 16 year old teen who is playing a shooter for the first time
sheâs kind of cute, i guess
.
Jenos
i can never tell if iâm going to absolutely destroy you or if youâre gonna kick my ass
*cutely holds you up so the whole team can shoot you to death*
kamehameha
youâre a healer??? i guess???
your character has such deep lore and i bet you donât even know half of it
.
Khan
one day you were playing and your team desperately needed a tank. you picked the first one you saw. suddenly, youâre lianâs foot stool
despite 2 layers of heavy armor, youâd still let this man walk all over you
âthis skin is really cool, wish it wasnât behind a pay wall...â
YEET
you actually know the gameâs lore, for some reason
.
Kinessa
i never trust people who are good at a sniper. if youâre bad thatâs natural and youâre 99% of the population. if youâre good you are definitely up to something
youâd sell your sister for 5 pennies if you could
youâre missing from the team all game and somehow have the most kills
âwe have a kinessa???â
you are an urban legend to your team
.
Koga
someoneâs been watching naruto
you are so shit at the game. like iâm sorry. no oneâs good at koga iâm so sorry
how do you have so many skins for one character???
youâre always missing from the point
healers hate you. so does the enemy kinessa.
.
Lex
quit the game /nm
âwho mains lex in 2021??? lmao???â
wall hacks, aimbot, and itâs all legal for you as an ability. you are a hacker in a world of puny vanillas. you like it easy so you go for the easy min max character. have fun getting hated
you think heâs hot and press on his loading abilities just so he can scold you and you can hear him being mad at you
*bonk* go to horny jail
.
Lian
"she could step on meâ
you used to main some sort of healer but switched over when you got sick of everyone being needy
you can hold a point all on your own for a really really long time but the moment your team gets there you start flunking
you wish you had more skins for her
you donât
.
Maeve
so imagine this. it was like 2018 and you were just chilling playing the game. you kept getting killed by maeve. in every game. she was in every game you went to and she kept killing you over and over and over again. you got frustrated, snapped, and bought her to see if you could do the same to others. you are now the maeve in every game. the cycle repeats.
your whole team doubts you but then you casually get a quad kill and they just sort of look away
you die a total of two times each round and 99% of the time itâs because you go too fast and fall off the map
you repeat everything she says in her accent because you think itâs cute
âwelcome to ze meant streets, kitten!â âcan you shut the fuck upâ âi hate to cut and run, he-he!â
.
Makoa
you have the plushie skin or the beta skin, otherwise you donât main and only play casually stop lying to yourself
âattack turtle go brrrâ
youâre really good if you get paired with a good healer
otherwise youâre useless
you wish you could get better teammates because you could really thrive with an organized group. but on paladins you wonât get that, iâm sorry-
.
MalâDamba
i always forget this guy is even in the game
youâre definitely under 6 foot IRL
you have an older sibling you always fight with
youâd love to have a snake irl
youâre really chill outside of the game, but when playing you hella rage
.
Moji
you are so precious
but also such a little shit
you annoy me but i also want to give you a hug
âletâs go guys!! to the point!! wheee!!â
please never change but also get out of my sight
.
Octavia
you always main the new character until the new person drops
somehow always have enough credits to buy the new champion whenever they come out
you donât like having a stable main cuz you get bored
you like hanging out at the training rage
hate siege and love team death match, you like your games quick
.
Pip
you are the worst and best thing to ever happen to this game
you only pick him to heal yourself and hardly ever heal your team
no one notices you there until you ult
then you get focused
honestly you just seem like you wanna do your thing and i can respect that
.
Raum
you probably go to therapy or desperately need it
âBIG MAN BIG. HE IS BIG. BRRRRâ
you always love the demons in media
you like being in charge of the team and wreck the point any time you are there, you like fighting on your own but having a healer nearby is nice too
you probably have daddy issues
.
Ruckus
you think ruckusâ and boltâs dynamic is cool and thatâs one of the main reasons you started playing him
heâs the only tank you can play
you used to main either inara or ying at some point but chose violence instead
really short irl. you physically relate to ruckus and spiritually to bolt.
âfunny goblin man :)â
.
Seris
certified girlboss
you can hold an objective all on your own or heal your whole team no problem. either way you are SLAYING
âalright. whoâs ass am i kicking today?â
mum energy is inferior to inara but still kind of there
iâm like 50% sure you have a foot fetish
.
Sha Lin
*pointing and chanting* incel, incel, ince-
whether thatâs about you or the character you can decide
you like minecraft bedwars on the side
âif i donât get this headshot i am literally going to spontaneously combustâ
really useful when thereâs no other long distance people - otherwise a nuisance
.
Skye
AWOOGA *jaw drops to ground, eyes roll out of head* BOOBA BOOBA BOOBA
you bought her for the tiddies, didnât you?
sheâs actually really satisfying to play once you get the hang of her, but can be real tough on rough days
you need a break i think - maybe play some other game for a bit?
*casually gets team kill with ult*
.
Strix
you own at least one pretty knife
you played him when he was unlocked on rotation, fell in love, and spent a whole evening collecting credits to buy him fully
âhaha bird manâ
iâve said what i said about snipers. if youâre actually good at him you are hiding a body somewhere. i fear you.
why does everyone ship him with viktor????
.
Talus
little furry child
he reminds me of tommyinnit because he is small and annoying
if you play him you are tall and intimidatingÂ
iâm friends with a tall scary talus main
i canât say bad things please spare me
.
Terminus
you always ult at the worst time and just get killed again 5 seconds after
âhey losers watch thisâ *goes on the point, dies, revives, kills one person and dies again*
youâre only a good tank if you cooperate
you donât
on your own youâre a pretty good player
.
Tiberius
*sigh*
you think the cat is hot, donât you?
âhis accent is kinda cute tho heheâ
you saw that one ending scene in zootopia with the dancing tigers and it CHANGED you
you are probably a furry. if not your awakening is coming. be ready.
.
Torvald
youâve been playing this game for too long
youâve seen skins rise and fall. youâve seen nerfs and buffs. youâve seen reworks and remakes. you are ancient. older than the dragons and wiser than makoa. respect.
people see you on the opposing team and get really annoyed
âthe point is really crowded, we canât move inâ âdonât worry guys, my ult is charged upâ
youâre really good at all the characters but you like this guy a lot because you think heâs funky fresh
.
Tyra
youâre either new to the game or have been playing for too long
either way you can KICK ASS but you need to keep behind your team to do the most damage
flanks are the bane of you, especially the fast jumpy ones
you really want one of the cooler skins but you can only ever get the basic ones. such is the curse of maining one of the OG characters.
âbite meâ
.
Viktor
you are level 100+ guaranteed, and everyone fears you
âoh shit they got a victor. flank focus himâ
you probably play COD and CS:GO normally and wanted to go with something familiar and easy. your skill from the other more advanced games DWARFS everyone else
but why are you playing âguy with gun 132âł in a game with magical elves and fairies. like come on bro.
you donât have any in-game friends because paladins is your guilty pleasure game you would never admit to
.
Vivian
âstep on meâ syndrome cranked up to 100%
this woman could spit on you and youâd still respect her more than your own mother. good for you
âiâm not a simp. iâm just tier 3 subbed to pokimane ironicallyâ
you sweat the game hardcore. former victor main or heâs your secondary.
youâve got her on level 50+ at least
.
Vora
like the maeve mains but somehow worse
bought her out of spite or played her while she was on rotation, now here you are grinding credits for her a day after she became unavailable
honestly youâre really good at the game i have nothing else to say
you enjoy the newer characters more than the OGs - youâre either a former vivian or lian main
you miss the play of the game feature in the game because youâd get all of them with this girl
.
Willo
you seem like the moji mains at first but show your true colors soon after
âfuck youâ x50
you are a trash talker on max overdrive. you need to sit down, do some breathing exercises and have a drink.
you hate your own team more than the opposing guys
when you see a willow on the opposing team you make it your sole goal to eliminate her as many times as humanely possible
.
Yagorath
i bet you didnât know she was canonically female until you read this
you donât like sweating too much so you pick the tank that leaves you heavily relying on your healers and damages
you can hold a point really well so you like siege and onslaught
âare vora and yagorath connected in the lore somehow and do i really care?â
you have a friend who you always party up with to be your healer, otherwise you might switch to another character
.
Ying
âtanks love me, flanks hate meâ
you are too powerful. literally. how are you so strong
youâve mastered the most difficult healer in the game. the others are really easy for you to play but you have trouble with seris
motivate your team a lot but start shading and trash talking if they donât cooperate
youâll gladly play someone else for a long while and like taking breaks from her
.
Zhin
this is your first main after switching over from overwatch. we can smell it on you.
youâre really annoyed with his personality and voice lines but the character is too good to play for you to pass him up for that. you respond to his voice lines aloud very aggressively to let him know heâs an ass
âYES ZHIN HEALERS ARENâT USELESS YOU SELFISH PRICKâ
you try your best but youâre not a great team player
infinite trips on a good day, die repeatedly without kills on a bad one and you switch over to vora or skye for a bit.
.
this took me hours to write out pls leave reblog and note thanks uwu

Awesome XiaoMi Roborock S50 S55 Larut, Matang dan Selama Huge Discount
Flip the Roborock S5 above and you're going to find two black rubber wheels on both sides, a multi-directional wheel in front, and a three-spoke side brush to the left. Between the wheels are the combination rubber and bristle roller brush. Though like the brush around the Eufy Robovac 30c, the S5's roller brush remained free of hair and fuzz. Design The security company assessed the safety of four different robot vacuums, including the Roborock S55 and the Roomba 980. The Roborock S55 performed the worst; AV-Test said that this was"Due partly to gross security deficiencies in data transmission, the transfer of data to third parties, the program's unexplainable thirst for data, as well as a very clear need for progress in the announcement on the handling of customer data." As per a Roborock agent, although the Roborock S5 uses the exact same app produced by Xiaomi since the S55 (Xiaomi is an investor in Roborock), map data is saved locally on the robot and just goes into the Cloud when a user views the map on the smartphone program.Up to 20 maps are saved in the Cloud in any certain time, and so are automatically deleted after a year. When users delete a map in the program, it's also eliminated in the Cloud. Exactly what the Roborock S5 lacked cleaning thoroughness, it made up for with speed, cleaning our hardwood and carpeting test region at an average of 15 minutes and 22 seconds, nearly a full hour quicker than the Roomba 690 and 45 minutes quickly compared to Shark Ion R85. It wasn't quite as quickly as the Neato Botvac D7, that cleaned the test region in a mean of 10 minutes.Â

We're enthused about zone cleaning to the Roborock S5, as it is a great way to perform a cleaning of a hall or kitchen. From the primary display on the app, you are able to draw boxes across the map areas you need vacuumed. Unlike the Roomba i7+ and also the Neato Botvac D7, you can't save or name the zones, which usually means you have to redraw every time to the place that you wish to wash them. Adding to the confusion is a Edit Map button on the main screen which lets you draw on virtual barrier cassette and no-go zones. Among our favourite design components of the Robovac S5 is its own"hood" Flip up the thin piece and you'll come across the ample dustbin hidden in the center, together with a index light and system reset button.The S5 was the real robot vacuum we examined that had an area to hold the tool for cleaning the brush roll, a smart way to keep while enhancing the aesthetic. An indented section near the back is supposed to hold the microfiber mop module. In 63.8 decibels, the Roborock S5 was clearly louder than the Shark Ion R85 (59.2). We were able to have a conversation as the vacuum worked around us but raised our voices. In our lab tests, the Roborock S5 performed well, but not outstandingly so. On hardwood and carpeting, it picked up an average of 96.2 percent of those Cheerios strewn throughout the test region, which was marginally less than the iRobot Roomba 690 (99.5 percent), the Neato Botvac D7 (99.8) and the Shark Ion R85, which divides a perfect 100 percent with this test.Â

The Roborock S5 steps 13.8 inches in diameter, more than an inch bigger than the Shark Ion R85; it is also larger than the 13-inch iRobot Roomba 690 and the 13.2-inch Neato Botvac D7. Installation and app We were hesitant to provide the S5 free reign to wash if it decided to try and wash our carpet, so we used the spot-cleaning mode, which cleans a 1.5- meter (4.9 feet) area around wherever the S5 is placed. Turns our hesitations were unfounded. The Roborock S5 made about as much water as a wet Swiffer pad onto the ground. If it had cleaned as well as a Swiffer does.Security concerns Picking up dog hair on both the hardwood and carpet stymied many of the robot vacuums we tested, such as the Roborock S5;it picked up just 79.5% of pet hair--10 percent less than the Botvac D7 and 8.5 percent less than the Ion R85. However, the S5 did best the Roomba 690's 73.3 percent pet hair pickup rate. Mopping performance Much like the program that accompanies the Mi Home program, the Eufy Robovac 30C is designed to control house smart devices. The layout is not instinctive, while the vacuum part of this app is robust. Overall, the Roborock S5 accumulated an average of 86.8 percent of all test debris on carpet--a performance on a level with all the Neato Botvac D7, but well below the Shark Ion R85's 97.2 percent. The S5's hardwood performance told a similar story, picking up an average of 83.9 percent of all test debris. It was bested by the Botvac D7 by 12 percent.Â

The Roborock S5 distinguishes itself with a mopping quality that's unique one of the robot vacuums we analyzed, but unfortunately, its mopping art is genuinely helpful. A half-inch thin disk with a microfiber pad resides beneath the rear of the vacuum. Fill out the disc using water, click it adjust the Cleanup mode in the program and you are ready to clean. The screen shows the place cleaning time and also our favourite item of information--staying battery lifetime. Along the bottom are icons for Go, Dock, Clean and Zoned Cleanup. In the center of the robot is a increased laser cap on the Neato Botvac D7 using a dab of beneath, very similar to the one. Over the cover are bodily buttons for spot cleaning, on/off and recharging. Perhaps due to the white colour, the wall detectors on the front and side of the S5 are more noticeable than on other models, but they don't detract in the bot appearance.We were impressed with how the Roborock S5 approached walls and obstacles. The bumper on the Roomba 690 appeared to announce that it struck something with clunk; the S5 was more polite. The robot slows its strategy and its side brush before gingerly approaching an obstruction nonetheless, when the S5 chose an item was approachable, it approached with gusto. The S5 pushed chairs and dog bowls than the Shark Ion R85 and also the Neato Botvac D7. It wasn't destructive, but I wouldn't leave a fragile vase onto a lightweight plant stand around during a cleanup. When the Roborock S5 get its bearings, it cleaned regions in a exact, back-and-forth snake pattern.

 The robot vacuum quickly found its way through the maze beneath our dining room table, easily weaving its way to the other. We appreciated how closely the S5 hewed to walls and chair legs;it tackled walls and edges tightly as the Neato Botvac D7. The van was also smart enough to completely avoid a thick pile rug that felled additional robot vacuums, but its taller height meant it didn't fit under one of our seats or our low-clearance couch. Despite its size, the Roborock S5 deftly maneuvered through tight spaces. At 3.8 inches high, the S5 sits straight between the 3.9-inch Botvac D7 and the 3.7-inch Roomba 690. While we do not love the laser cover in the center, the characteristic was significantly less obtrusive than the one about the D7, which has a massive overhang and penchant for getting stuck under living room seats. If you're adding a robot vacuum cleaner to your home, you want it to look great --especially if it's docked on your living room. The Roborock S5 eschews the black-and-grey color scheme adopted by other vacuums for white, with muted silver trim around the rim. If you guessed the Go icon could initiate a cleaning cycle, you would be wrong. Instead, Go directs the S5 into a stage on the cleansing map for the bot to perform a spot cleaning. A general vacuuming cycle is initiated by activating the icon. Buried in the Preferences menu are five distinct Cleanup modes : Quiet, Balanced, Turbo, MAX and Mop. The program, and by extension, the vacuum, retains the mode last used.

Cleaning performance The Roborock S5 may also be controlled via Amazon Alexa and Google Home. But don't expect to access any features the only choices are On and Off, which prompts to bot to come back to its foundation. Google Assistant adds"Return to Dock," which sends the robot house, rather than Stop, which divides the vacuum in its tracks. "Beginning the cleanup," a cheery voice announces from deep within the Roborock S5. Rather than a series of Morse code-like beeps and chimes employed by the Neato Botvac D7, the Shark Ion R85 and many other appliances, the S5 admits what it's likely to do in easy-to-understand terminology prompts. The Roborock S5 is mostly controlled via the Mi Home program (Android and iOS). Connecting the robot into the program and also to our home wi-fi network took 2 tries, mostly because the directions for pairing the bot into the Wi-Fi network weren't too clear. Instructions that were abstruse quickly became a recurring motif of the S5. The manual recommends running a vacuum cycle that is regular . We did so, but it didn't seem to help. The S5 left the mopped area dull and a little sticky. If it had been possible to use something in addition to water in the mop tank it would have performed better. The black-and-white pier for your Roborock S5 is slightly taller than the vacuum itself. A clear plastic mat attaches to the dock, but it's only needed if you plan on using the attachment. Notice that tabbed Saving Mode is currently in beta and must be toggled on separately under Vacuum Settings in the app. We spent several test runs re-mapping our first floor due to this map not saving mechanically. Both the expensive iRobot Roomba and the Botvac D7 can store floor plans.

Professional XiaoMi Roborock S50 S55 Sungai Dua
Flip the Roborock S5 over and you'll discover two black rubber wheels on either side, a multi-directional wheel at front, and a three-spoke side brush to the leftside. Between the black wheels are the combination rubber and bristle roller brush. Though like the brush around the Eufy Robovac 30c, the S5's roller brush stayed remarkably free of hair and fuzz. Design The security firm AV-Test recently evaluated the security of four different robot vacuums, including the Roborock S55 and the iRobot Roomba 980. The Roborock S55 performed the worst; AV-Test explained this was"Due partially to gross safety deficiencies in data transmission, the transport of information to third parties, the app's unexplainable thirst for data, in addition to a clear need for improvement in the announcement on the handling of consumer data." As per a Roborock representative, though the Roborock S5 employs the exact same app made by Xiaomi as the S55 (Xiaomi is an investor in Roborock), map data is stored locally on the robot, and just goes into the Cloud when a user views the map onto the smartphone program.

As much as 20 maps are stored in the Cloud in any time and are deleted after a year. When users delete a map from the program, it's also removed from the Cloud. Exactly what the Roborock S5 lacked cleaning thoroughness, it made up for with speed, cleaning our hardwood and carpeting test region at an average of 15 minutes and 22 seconds, almost a complete hour faster than the Roomba 690 and 45 minutes fast compared to Shark Ion R85. It was as fast as the Neato Botvac D7, that cleaned the test area at a mean of 10 minutes. We're excited about zone cleaning to the Roborock S5, since it is a wonderful way to perform a daily cleaning of a hall or kitchen. From the main screen on the app, you are able to draw boxes around the map areas you need vacuumed. Contrary to the Roomba i7+ and also the Neato Botvac D7, you cannot save or title the zones, which usually means you need to redraw every time to the place that you wish to clean them. Adding to the confusion is a Edit Map button on the screen that allows you draw virtual barrier tape and no-go zones. Among our favorite design components of this Robovac S5 is its own"hood." Flip up the plastic piece and you will come across the ample dustbin hidden in the middle, together with a index light and system reset button.

The S5 was the robot vacuum we reviewed that had an area to hold the tool for cleaning the brush roll, a smart means to maintain functionality whilst improving the aesthetic. An section close to the rear is meant to maintain the microfiber mop module. At 63.8 decibels, the Roborock S5 was noticeably louder than the Shark Ion R85 (59.2). We were able to have a conversation although the vacuum worked around us, but definitely raised our voices. In our laboratory tests, the Roborock S5 performed well, but not outstandingly so. On hardwood and carpet, it picked up an average of 96.2% of the Cheerios strewn throughout the test region, which was slightly less than the iRobot Roomba 690 (99.5 percent), the Neato Botvac D7 (99.8) and the Shark Ion R85, that scooped a perfect 100 percent on this evaluation. The Roborock S5 steps 13.8 inches in diameter, more than an inch bigger than the Shark Ion R85; it's also larger than the 13-inch iRobot Roomba 690 and the 13.2-inch Neato Botvac D7. Installation and app We were hesitant to give the S5 free reign to wash in case it decided to try and clean our rug, therefore we used the spot-cleaning mode, which sheds a 1.5- meter (4.9 ft ) area around wherever the S5 is put. Turns our hesitations were unfounded. The Roborock S5 made about as much water as a wet Swiffer pad on the floor. If only it had cleaned as well as a Swiffer does.

Security concerns Picking pet hair on both the hardwood and carpet stymied many of those robot vacuums we analyzed, including the Roborock S5;it picked up only 79.5% of pet hair--10 percent less compared to Botvac D7 and 8.5 percent less compared to Ion R85. On the other hand, the S5 did finest the Roomba 690's 73.3 percent pet hair pickup rate. Mopping performance Much like the app that accompanies the Mi Home program, the Eufy Robovac 30C was made to control home devices. The layout is not intuitive while the vacuum section of the app is strong. Overall, the Roborock S5 accumulated an average of 86.8% of all test debris on carpet--a performance on a level with all the Neato Botvac D7, but well below the Shark Ion R85's 97.2 percent. The S5's hardwood performance told a similar story, picking up an average of 83.9% of test debris. The Botvac D7 bested it by 12 percent. The Roborock S5 distinguishes itself with a mapping quality that's unique one of the robot vacuums we analyzed, but unfortunately, its prowess is truly useful. A half-inch thin, half-moon-shaped disc with a microfiber pad attached with velcro clicks resides under the back of the vacuum. Fill out the disc using water, click it in, adjust the Cleanup mode in the program and you are ready to clean. The screen shows the most recent area in meters, cleaning time and also our favorite item of information. Along the bottom are icons for Go, Dock, Clean and Zoned Cleanup. In the robot's middle is a laser cover using a splash of underneath around the Neato Botvac D7. Above the cover are physical buttons for spot cleaning, on/off and recharging. Perhaps due to the white color, the wall detectors on the front and side of the S5 are more conspicuous than on other versions, but they don't detract from the bot appearance.

We were impressed with how lightly the Roborock S5 approached walls and obstacles. The bumper on the Roomba 690 seemed to announce it struck something with clunk; the S5 was much more considerate. The robot slows its strategy and its side brush before gingerly approaching an obstruction . The S5 pushed on chairs and dog bowls than the Shark Ion R85 and the Neato Botvac D7. It was not harmful, but I would not leave a vase on a plant stand around during a cleanup. When the Roborock S5 get its claws, it cleaned regions in a detailed back-and-forth snake pattern. The robot vacuum found its way beneath our dining room tableweaving its way to another. We appreciated how hewed to walls and about seat legs;it tackled walls and edges as the Neato Botvac D7. The van was also smart enough to fully avert a thick pile rug which felled additional robot vacuums, but its taller height meant it didn't fit under our chairs or our low-clearance couch. Despite its size, the Roborock S5 deftly maneuvered through tight spaces. At 3.8 inches , the S5 sits straight between the 3.9-inch Botvac D7 and the 3.7-inch Roomba 690. While we don't adore the laser cover at the center, the feature was less obtrusive than the one on the D7, which has a massive overhang and penchant for getting stuck under room seats. You want it to look great -- particularly if it's docked on your living room if you are adding a robot vacuum to your house. The Roborock S5 eschews the black-and-gray color scheme embraced by other vacuums for white, with silver trim around the rim. If you guessed that the Go icon could initiate a cleaning cycle, you would be wrong. Instead, God directs the S5 into a user-chosen point on the cleansing map for the bot to perform a spot cleaning. By activating the icon that is sterile, a general vacuuming cycle is initiated. Buried in the Preferences menu are five distinct Cleanup modes : Quiet, Balanced, Turbo, MAX and Mop. The app, and by extension, the vacuum, retains the mode last used.

Cleaning performance The Roborock S5 may also be controlled via Amazon Alexa and Google Home. Don't expect to get any complex features the options are On and Off, which prompts to bot to come back to its base. Google Assistant adds"Return to Dock," which sends the robot house, as opposed to Stop, which divides the vacuum in its paths. "Beginning the cleanup," a cheery voice announces from deep within the Roborock S5. Rather than a string of Morse code-like beeps and chimes employed by the Neato Botvac D7, the Shark Ion R85 and many other modern appliances, the S5 admits what it is likely to perform in easy-to-understand language prompts. The Roborock S5 is primarily controlled via the Mi Home app (Android and iOS). Connecting the robot to the app and also to our home wi-fi network took two triesbecause the directions for pairing the bot into the Wi-Fi network were not too apparent. Abstruse instructions turned into a recurring theme of this S5. The manual recommends running a vacuum cycle that is normal over the region at least three times. We did so, but it did not seem to help. The S5 left the mapped area dull and a little tacky. If it was possible to use something along with water in the tank, then maybe it would have performed better. The black-and-white pier for the Roborock S5 is marginally taller than the vacuum. A large, clear plastic mat attaches to the dock, but it is only needed if you plan on utilizing the attachment. Notice that tabbed Saving Mode is currently in beta and must be toggled on individually under Vacuum Settings in the app. We spent several test runs re-mapping our first floor due to this map not saving mechanically. Both the iRobot Roomba and also the D7 can save multiple floor plans.

Week 394
Happy Thursday! I wrote last week that Xcode 13 Beta 3 was released, and indeed it was. And then, two days later, it was re-released. According to @XcodeReleases it seems it's mostly the same, but the re-release fixes something related to Xcode Could (for those who were lucky to get access to the beta đ„ș).

Could Apple Have Released the iOS 13.1 Beta Early to Avoid iPhone Tariffs?
Earlier this month, Apple did something highly unusual. It released the first beta version of iOS 13.1 before iOS 13 was even released (or done with its own beta testing cycle, for that matter). That move caused a bit of a stir among the beta testing and developer communities, along with the... https://www.idropnews.com/rumors/could-apple-have-released-the-ios-13-1-beta-early-to-avoid-iphone-tariffs/116029/

iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that powers many of the companyâs mobile devices, including the iPhone and iPod Touch; the term also included the versions running on iPads until the name iPadOS was introduced with version 13 in 2019. It is the worldâs second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses.[12]
Unveiled in 2007 for the first-generation iPhone, iOS has since been extended to support other Apple devices such as the iPod Touch (September 2007) and the iPad (introduced: January 2010; availability: April 2010.) As of March 2018, Appleâs App Store contains more than 2.1 million iOS applications, 1 million of which are native for iPads.[13] These mobile apps have collectively been downloaded more than 130 billion times.
Major versions of iOS are released annually. The current stable version, iOS 14, was released to the public on September 16, 2020.[14] It brought many user interface changes, including the ability to place widgets on the home screen, a compact UI for both Siri and phone calls, and the ability to change both the default web browser and email apps. No devices were dropped, as all devices supported by iOS 13 are able to run iOS 14.

In 2005, when Steve Jobs began planning the iPhone, he had a choice to either âshrink the Mac, which would be an epic feat of engineering, or enlarge the iPodâ. Jobs favored the former approach but pitted the Macintosh and iPod teams, led by Scott Forstall and Tony Fadell, respectively, against each other in an internal competition, with Forstall winning by creating the iPhone OS. The decision enabled the success of the iPhone as a platform for third-party developers: using a well-known desktop operating system as its basis allowed the many third-party Mac developers to write software for the iPhone with minimal retraining. Forstall was also responsible for creating a software development kit for programmers to build iPhone apps, as well as an App Store within iTunes.[15][16]
The operating system was unveiled with the iPhone at the Macworld Conference & Expo on January 9, 2007, and released in June of that year.[17][18][19] At the time of its unveiling in January, Steve Jobs claimed: âiPhone runs OS Xâ and runs âdesktop class applicationsâ,[20][21] but at the time of the iPhoneâs release, the operating system was renamed âiPhone OSâ.[22] Initially, third-party native applications were not supported. Jobsâ reasoning was that developers could build web applications through the Safari web browser that âwould behave like native apps on the iPhoneâ.[23][24] In October 2007, Apple announced that a native Software Development Kit (SDK) was under development and that they planned to put it âin developersâ hands in Februaryâ.[25][26][27] On March 6, 2008, Apple held a press event, announcing the iPhone SDK.[28][29]
The iOS App Store was opened on July 10, 2008 with an initial 500 applications available.[30] This quickly grew to 3,000 in September 2008,[31] 15,000 in January 2009,[32] 50,000 in June 2009,[33] 100,000 in November 2009,[34][35] 250,000 in August 2010,[36][37] 650,000 in July 2012,[38] 1 million in October 2013,[39][40] 2 million in June 2016,[41][42][43] and 2.2 million in January 2017.[44][45] As of March 2016, 1 million apps are natively compatible with the iPad tablet computer.[46] These apps have collectively been downloaded more than 130 billion times.[41] App intelligence firm Sensor Tower has estimated that the App Store will reach 5 million apps by the year 2020.[47]
In September 2007, Apple announced the iPod Touch, a redesigned iPod based on the iPhone form factor.[48] On January 27, 2010, Apple introduced their much-anticipated media tablet, the iPad, featuring a larger screen than the iPhone and iPod Touch, and designed for web browsing, media consumption, and reading, and offering multi-touch interaction with multimedia formats including newspapers, e-books, photos, videos, music, word processing documents, video games, and most existing iPhone apps using a 9.7-inch screen.[49][50][51] It also includes a mobile version of Safari for web browsing, as well as access to the App Store, iTunes Library, iBookstore, Contacts, and Notes. Content is downloadable via Wi-Fi and optional 3G service or synced through the userâs computer.[52] AT&T was initially the sole U.S. provider of 3G wireless access for the iPad.[53]
In June 2010, Apple rebranded iPhone OS as âiOSâ. The trademark âIOSâ had been used by Cisco for over a decade for its operating system, IOS, used on its routers. To avoid any potential lawsuit, Apple licensed the âIOSâ trademark from Cisco.[54]
The Apple Watch smartwatch was announced by Tim Cook on September 9, 2014, being introduced as a product with health and fitness-tracking.[55][56] It was released on April 24, 2015.[57][58][59] It uses watchOS as operative system, which is based on IOS.
On November 22nd, 2016, a five-second video file originally named âIMG_0942.MP4â started crashing iOS on a increasing count of devices, forcing users to reboot. It gained massive popularity through social media channels and messaging services.[60][61]
In October 2016, Apple opened its first iOS Developer Academy in Naples inside University of Naples Federico IIâs new campus.[62][63] The course is completely free, aimed at acquiring specific technical skills on the creation and management of applications for the Apple ecosystem platforms.[64] At the Academy there are also issues of business administration (business planning and business management with a focus on digital opportunities) and there is a path dedicated to the design of graphical interfaces. Students have the opportunity to participate in the âEnterprise Trackâ, an in-depth training experience on the entire life cycle of an app, from design to implementation, to security, troubleshooting, data storage and cloud usage.[65][66] As of 2020, the Academy graduated almost a thousand students from all over the world, who have worked on 400 app ideas and have already published about 50 apps on the iOS App Store. In the 2018/2019 academic year, students from more than 30 different countries arrived. 35 of these have been selected to attend the Worldwide Developer Conference, the annual Apple Developer Conference held annually in California in early June.[67][68]
Steve Jobs, Appleâs then CEO, introducing the iPad.
On June 3, 2019, iPadOS, the branded version of iOS for iPad, was announced at the 2019 WWDC; it was launched on September 25, 2019.[69]
Features
Interface
The iOS user interface is based upon direct manipulation, using multi-touch gestures such as swipe, tap, pinch, and reverse pinch. Interface control elements include sliders, switches, and buttons.[70] Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching between portrait and landscape mode). Various accessibility described in § Accessibility functions enable users with vision and hearing disabilities to properly use iOS.[71]
iOS devices boot to the homescreen, the primary navigation and information âhubâ on iOS devices, analogous to the desktop found on personal computers. iOS homescreens are typically made up of app icons and widgets; app icons launch the associated app, whereas widgets display live, auto-updating content, such as a weather forecast, the userâs email inbox, or a news ticker directly on the homescreen.[72]
Along the top of the screen is a status bar, showing information about the device and its connectivity. The status bar itself contains two elements, the Control Center and the Notification Center. The Control Center can be âpulledâ down from the top right of the notch, on the new iPhones, giving access to various toggles to manage the device more quickly without having to open the Settings. It is possible to manage brightness, volume, wireless connections, music player, etc.[73]
Instead, scrolling from the top left to the bottom will open the Notification Center, which in the latest versions of iOS is very similar to the lockscreen. It displays notifications in chronological order and groups them by application. From the notifications of some apps it is possible to interact directly, for example by replying a message directly from it. Notifications are sent in two modes, the important notifications that are displayed on the lock screen and signaled by a distinctive sound, accompanied by a warning banner and the app badge icon, and the secondary mode where they are displayed in the Notification Center, but they are not shown on the lock screen, nor are they indicated by warning banners, badge icons or sounds.[74][75]
It is possible to choose if notifications from an app can be shown on the lock screen, Notification Center, banner, or all three; whether the banner should be temporary or permanent; activate or deactivate the sound; choose whether to group by app or not and whether to show previews when locked. It is possible to turn off unwanted app notifications. Older notifications are automatically deleted after a few days.
A homescreen may be made up of several pages, between which the user can swipe back and forth, one of the ways to do this is to hold down on the âdotsâ shown on each page and swipe left or right.
To the right of the last page, the App Library lists and categorizes apps installed on the device. Apps within each category are arranged based on the frequency of their usage. In addition to a category for suggested apps, a ârecentâ category lists apps recently installed alongside App Clips recently accessed. Users can search for the app they want or browse them in alphabetical order.
iOS also integrates seamlessly with other programming frameworks and technologies, such as Apple Pay, HomeKit, HealthKit, and ResearchKit.
On iOS, the main page button is usually located at the top right. To go back in an application there is almost always a âbackâ button.
You can go back in 4 different ways, it varies depending on the context.
Press the âBackâ button at the top left of the display
Swipe right from the left edge of the screen (gesture)
Press the âFinishâ action at the top right of the screen
Scroll down on the screen content
The page title is practically always present and very visible, but it shrinks as the user scrolls down.
Navigation destinations that cannot be contained in the bottom tab bar can: be moved to a generic âMoreâ tab or appear as actions in the top left or top right of other destinations.

Modal views are single-screen activities that are displayed by swiping into the foreground, while allowing the previous screen to peek up, retreating into the background. You can ignore them by scrolling down or tapping âBackâ at the top.
Full screen views are media content such as photos or videos that take up the entire screen. They disappear on scrolling down.
Occasionally on iOS, important page actions appear on a lower toolbar.
Action menus can be activated by any button or by attempting to perform any action. They scroll from bottom to top.
On earlier iPhones with home button, screenshots can be created with the simultaneous press of the home and power buttons. In comparison to Android OS, which requires the buttons to be held down, a short press does suffice on iOS.[76] On the more recent iPhones which lack a physical home button, screenshots are captured using the volume-down and power buttons instead.[77]
A new feature in iOS 13 called âcontext menusâ shows related actions when you touch and hold an item. When the context menu is displayed, the background is blurred.[78]
To choose from a few options, a selection control is used. Selectors can appear anchored at the bottom or in line with the content (called date selectors). Date selectors take on the appearance of any other selection control, but with a column for day, month, and optionally year.
Alerts appear in the center of the screen, but there are also alerts that scroll up from the bottom of the screen (called âaction panelsâ). Destructive actions (such as eliminating any element) are colored red.
The official font of iOS is San Francisco. It is designed for small text readability, and is used throughout the operating system, including third-party apps.[78]
The icons are 180x180px in size for iPhones with a larger screen, usually models over 6 inches, including iPhone 11 Pro and iPhone 8 Plus, while itâs 120x120px on iPhones with smaller displays.[79]
Appleâs official design language is called Human Interface.[80]
Applications
iOS devices come with preinstalled apps developed by Apple including Mail, Maps, TV, Music, FaceTime, Wallet, Health, and many more.
Applications (âappsâ) are the most general form of application software that can be installed on iOS. They are downloaded from the official catalog of the App Store digital store, where apps are subjected to security checks before being made available to users. In June 2017, Apple updated its guidelines to specify that app developers will no longer have the ability to use custom prompts for encouraging users to leave reviews for their apps.[81][82] IOS applications can also be installed directly from an IPA file provided by the software distributor, via unofficial ways. They are written using iOS Software Development Kit (SDK) and, often, combined with Xcode, using officially supported programming languages, including Swift and Objective-C. Other companies have also created tools that allow for the development of native iOS apps using their respective programming languages.
Applications for iOS are mostly built using components of UIKit, a programming framework. It allows applications to have a consistent look and feel with the OS, nevertheless offering customization.
Elements automatically update along with iOS updates, automatically including new interface rules. UIKit elements are very adaptable, this allows developers to design a single app that looks the same on any iOS device. In addition to defining the iOS interface, UIKit defines the functionality of the application.
At first, Apple did not intend to release an SDK to developers, because they did not want third-party apps to be developed for iOS, building web apps instead. However, this technology never entered into common use, this led Apple to change its opinion, so in October 2007 the SDK for developers was announced, finally released on March 6, 2008.
The SDK includes an inclusive set of development tools,[83] including an audio mixer and an iPhone simulator. It is a free download for Mac users. It is not available for Microsoft Windows PCs. To test the application, get technical support, and distribute applications through App Store, developers are required to subscribe to the Apple Developer Program.
Over the years, the Apple Store apps surpassed multiple major milestones, including 50,000,[84] 100,000,[85] 250,000,[86] 500,000,[87] 1Â million,[88] and 2Â million apps.[89] The billionth application was installed on April 24, 2009.[90]
Home screen
The home screen, rendered by SpringBoard, displays application icons and a dock at the bottom where users can pin their most frequently used apps. The home screen appears whenever the user unlocks the device or presses the physical âHomeâ button while in another app.[91] Before iOS 4 on the iPhone 3GS (or later), the screenâs background could be customized only through jailbreaking, but can now be changed out-of-the-box. The screen has a status bar across the top to display data, such as time, battery level, and signal strength. The rest of the screen is devoted to the current application. When a passcode is set and a user switches on the device, the passcode must be entered at the Lock Screen before access to the Home screen is granted.[92]
In iPhone OS 3, Spotlight was introduced, allowing users to search media, apps, emails, contacts, messages, reminders, calendar events, and similar content. In iOS 7 and later, Spotlight is accessed by pulling down anywhere on the home screen (except for the top and bottom edges that open Notification Center and Control Center).[93][94] In iOS 9, there are two ways to access Spotlight. As with iOS 7 and 8, pulling down on any homescreen will show Spotlight. However, it can also be accessed as it was in iOS 3 â 6. This endows Spotlight with Siri suggestions, which include app suggestions, contact suggestions and news.[95] In iOS 10, Spotlight is at the top of the now-dedicated âTodayâ panel.[96]
Since iOS 3.2, users are able to set a background image for the Home Screen. This feature is only available on third-generation devicesâiPhone 3GS, third-generation iPod touch (iOS 4.0 or newer), and all iPad models (since iOS 3.2)âor newer.
iOS 7 introduced a parallax effect on the Home Screen, which shifts the deviceâs wallpaper and icons in response to the movement of the device, creating a 3D effect and an illusion of floating icons. This effect is also visible in the tab view of Mail and Safari.[97]
Researchers found that users organize icons on their homescreens based on usage frequency and relatedness of the applications, as well as for reasons of usability and aesthetics.[98]
System font
iOS originally used Helvetica as the system font. Apple switched to Helvetica Neue exclusively for the iPhone 4 and its Retina Display, and retained Helvetica as the system font for older iPhone devices on iOS 4.[99] With iOS 7, Apple announced that they would change the system font to Helvetica Neue Light, a decision that sparked criticism for inappropriate usage of a light, thin typeface for low-resolution mobile screens. Apple eventually chose Helvetica Neue instead.[100][101] The release of iOS 7 also introduced the ability to scale text or apply other forms of text accessibility changes through Settings.[102][103] With iOS 9, Apple changed the font to San Francisco, an Apple-designed font aimed at maximum legibility and font consistency across its product lineup.[104][105]
Folders
iOS 4 introduced folders, which can be created by dragging an application on top of another, and from then on, more items can be added to the folder using the same procedure. A title for the folder is automatically selected by the category of applications inside, but the name can also be edited by the user.[106] When apps inside folders receive notification badges, the individual numbers of notifications are added up and the total number is displayed as a notification badge on the folder itself.[106] Originally, folders on an iPhone could include up to 12 apps, while folders on iPad could include 20.[107] With increasing display sizes on newer iPhone hardware, iOS 7 updated the folders with pages similar to the home screen layout, allowing for a significant expansion of folder functionality. Each page of a folder can contain up to nine apps, and there can be 15 pages in total, allowing for a total of 135 apps in a single folder.[108] In iOS 9, Apple updated folder sizes for iPad hardware, allowing for 16 apps per page, still at 15 pages maximum, increasing the total to 240 apps.[109]
Notification Center
Before iOS 5, notifications were delivered in a modal window and couldnât be viewed after being dismissed. In iOS 5, Apple introduced Notification Center, which allows users to view a history of notifications. The user can tap a notification to open its corresponding app, or clear it.[110] Notifications are now delivered in banners that appear briefly at the top of the screen. If a user taps a received notification, the application that sent the notification will be opened. Users can also choose to view notifications in modal alert windows by adjusting the applicationâs notification settings. Introduced with iOS 8, widgets are now accessible through the Notification Center, defined by 3rd parties.
When an app sends a notification while closed, a red badge appears on its icon. This badge tells the user, at a glance, how many notifications that app has sent. Opening the app clears the badge.
Accessibility
iOS offers various accessibility features to help users with vision and hearing disabilities. One major feature, VoiceOver, provides a voice reading information on the screen, including contextual buttons, icons, links and other user interface elements, and allows the user to navigate the operating system through gestures. Any apps with default controls and developed with a UIKit framework gets VoiceOver functionality built in.[111] One example includes holding up the iPhone to take a photo, with VoiceOver describing the photo scenery.[112] As part of a âMade for iPhoneâ program, introduced with the release of iOS 7 in 2013, Apple has developed technology to use Bluetooth and a special technology protocol to let compatible third-party equipment connect with iPhones and iPads for streaming audio directly to a userâs ears. Additional customization available for Made for iPhone products include battery tracking and adjustable sound settings for different environments.[113][114] Apple made further efforts for accessibility for the release of iOS 10 in 2016, adding a new pronunciation editor to VoiceOver, adding a Magnifier setting to enlarge objects through the deviceâs camera, software TTY support for deaf people to make phone calls from the iPhone, and giving tutorials and guidelines for third-party developers to incorporate proper accessibility functions into their apps.[115]
In 2012, Liat Kornowski from The Atlantic wrote that âthe iPhone has turned out to be one of the most revolutionary developments since the invention of Brailleâ,[116] and in 2016, Steven Aquino of TechCrunch described Apple as âleading the way in assistive technologyâ, with Sarah Herrlinger, Senior Manager for Global Accessibility Policy and Initiatives at Apple, stating that âWe see accessibility as a basic human right. Building into the core of our products supports a vision of an inclusive world where opportunity and access to information are barrier-free, empowering individuals with disabilities to achieve their goalsâ.[117]
Criticism has been aimed at iOS depending on both internet connection (either WiFi or through iTunes) and a working SIM card upon first activation.[118] This restriction has been loosened in iOS 12, which no longer requires the latter.[119]
Multitasking
Multitasking for iOS was first released in June 2010 along with the release of iOS 4.[120][121] Only certain devicesâiPhone 4, iPhone 3GS, and iPod Touch 3rd generationâwere able to multitask.[122] The iPad did not get multitasking until iOS 4.2.1 in that November.[123]
The implementation of multitasking in iOS has been criticized for its approach, which limits the work that applications in the background can perform to a limited function set and requires application developers to add explicit support for it.[122][124]
Before iOS 4, multitasking was limited to a selection of the applications Apple included on the device. Users could however âjailbreakâ their device in order to unofficially multitask.[125] Starting with iOS 4, on third-generation and newer iOS devices, multitasking is supported through seven background APIs:[126]
Background audio â application continues to run in the background as long as it is playing audio or video content[127]
Voice over IP â application is suspended when a phone call is not in progress[127]
Background location â application is notified of location changes[127]
Push notifications
Local notifications â application schedules local notifications to be delivered at a predetermined time[127]
Task completion â application asks the system for extra time to complete a given task[127]
Fast app switching â application does not execute any code and may be removed from memory at any time[127]
In iOS 5, three new background APIs were introduced:
Newsstand â application can download content in the background to be ready for the user[127]
External Accessory â application communicates with an external accessory and shares data at regular intervals[127]
Bluetooth Accessory â application communicates with a bluetooth accessory and shares data at regular intervals[127]
In iOS 7, Apple introduced a new multitasking feature, providing all apps with the ability to perform background updates. This feature prefers to update the userâs most frequently used apps and prefers to use Wi-Fi networks over a cellular network, without markedly reducing the deviceâs battery life.
Switching applications
In iOS 4.0 to iOS 6.x, double-clicking the home button activates the application switcher. A scrollable dock-style interface appears from the bottom, moving the contents of the screen up. Choosing an icon switches to an application. To the far left are icons which function as music controls, a rotation lock, and on iOS 4.2 and above, a volume controller.
With the introduction of iOS 7, double-clicking the home button also activates the application switcher. However, unlike previous versions it displays screenshots of open applications on top of the icon and horizontal scrolling allows for browsing through previous apps, and it is possible to close applications by dragging them up, similar to how WebOS handled multiple cards.[128]
With the introduction of iOS 9, the application switcher received a significant visual change; while still retaining the card metaphor introduced in iOS 7, the application icon is smaller, and appears above the screenshot (which is now larger, due to the removal of âRecent and Favorite Contactsâ), and each application âcardâ overlaps the other, forming a rolodex effect as the user scrolls. Now, instead of the home screen appearing at the leftmost of the application switcher, it appears rightmost.[129] In iOS 11, the application switcher receives a major redesign. In the iPad, the Control Center and app switcher are combined. The app switcher in the iPad can also be accessed by swiping up from the bottom. In the iPhone, the app switcher cannot be accessed if there are no apps in the RAM.
Ending tasks
In iOS 4.0 to iOS 6.x, briefly holding the icons in the application switcher makes them âjiggleâ (similarly to the homescreen) and allows the user to force quit the applications by tapping the red minus circle that appears at the corner of the appâs icon.[130] Clearing applications from multitasking stayed the same from iOS 4.0 through 6.1.6, the last version of iOS 6.
As of iOS 7, the process has become faster and easier. In iOS 7, instead of holding the icons to close them, they are closed by simply swiping them upwards off the screen. Up to three apps can be cleared at a time compared to one in versions up to iOS 6.1.6.[131]
Task completion
Task completion allows apps to continue a certain task after the app has been suspended.[132][133] As of iOS 4.0, apps can request up to ten minutes to complete a task in the background.[134] This doesnât extend to background up- and downloads though (e.g. if a user starts a download in one application, it wonât finish if they switch away from the application).
Siri
Main article: Siri
Siri () is an intelligent personal assistant integrated into iOS. The assistant uses voice queries and a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. The software adapts to usersâ individual language usages, searches, and preferences, with continuing use. Returned results are individualized.
Originally released as an app for iOS in February 2010,[135] it was acquired by Apple two months later,[136][137][138] and then integrated into iPhone 4S at its release in October 2011.[139][140] At that time, the separate app was also removed from the iOS App Store.[141]
Siri supports a wide range of user commands, including performing phone actions, checking basic information, scheduling events and reminders, handling device settings, searching the Internet, navigating areas, finding information on entertainment, and is able to engage with iOS-integrated apps.[142] With the release of iOS 10 in 2016, Apple opened up limited third-party access to Siri, including third-party messaging apps, as well as payments, ride-sharing, and Internet calling apps.[143][144] With the release of iOS 11, Apple updated Siriâs voices for more clear, human voices, it now supports follow-up questions and language translation, and additional third-party actions.[145][146]
Game Center
Game Center is an online multiplayer âsocial gaming networkâ[147] released by Apple.[148] It allows users to âinvite friends to play a game, start a multiplayer game through matchmaking, track their achievements, and compare their high scores on a leaderboard.â iOS 5 and above adds support for profile photos.[147]
Game Center was announced during an iOS 4 preview event hosted by Apple on April 8, 2010. A preview was released to registered Apple developers in August.[147] It was released on September 8, 2010 with iOS 4.1 on iPhone 4, iPhone 3GS, and iPod Touch 2nd generation through 4th generation.[149] Game Center made its public debut on the iPad with iOS 4.2.1.[150] There is no support for the iPhone 3G, original iPhone and the first-generation iPod Touch (the latter two devices did not have Game Center because they did not get iOS 4).[151] However, Game Center is unofficially available on the iPhone 3G via a hack.[152]
Hardware
The main hardware platform for iOS is the ARM architecture (the ARMv7, ARMv8-A, ARMv8.2-A, ARMv8.3-A). iOS releases before iOS 7 can only be run on iOS devices with 32-bit ARM processors (ARMv6 and ARMv7-A architectures). In 2013, iOS 7 was released with full 64-bit support (which includes a native 64-bit kernel, libraries, drivers as well as all built-in applications),[153] after Apple announced that they were switching to 64-bit ARMv8-A processors with the introduction of the Apple A7 chip.[154] 64-bit support was also enforced for all apps in the App Store; All new apps submitted to the App Store with a deadline of February 2015, and all app updates submitted to the App Store with a deadline of June 1, 2015.[155] iOS 11 drops support for all iOS devices with 32-bit ARM processors as well as 32-bit applications,[156][157] making iOS 64-bit only.[158]
Development
The iOS SDK (Software Development Kit) allows for the development of mobile apps on iOS.
While originally developing iPhone prior to its unveiling in 2007, Appleâs then-CEO Steve Jobs did not intend to let third-party developers build native apps for iOS, instead directing them to make web applications for the Safari web browser.[159] However, backlash from developers prompted the company to reconsider,[159] with Jobs announcing in October 2007 that Apple would have a software development kit available for developers by February 2008.[160][161] The SDK was released on March 6, 2008.[162][163]
The SDK is a free download for users of Mac personal computers.[164] It is not available for Microsoft Windows PCs.[164] The SDK contains sets giving developers access to various functions and services of iOS devices, such as hardware and software attributes.[165] It also contains an iPhone simulator to mimic the look and feel of the device on the computer while developing.[165] New versions of the SDK accompany new versions of iOS.[166][167] In order to test applications, get technical support, and distribute apps through App Store, developers are required to subscribe to the Apple Developer Program.[164]
Combined with Xcode, the iOS SDK helps developers write iOS apps using officially supported programming languages, including Swift and Objective-C.[168] Other companies have also created tools that allow for the development of native iOS apps using their respective programming languages.[169][170]
Update schedule
Apple provides major updates to the iOS operating system annually via iTunes and since iOS 5, also over-the-air.[172] The device checks an XML-based PLIST file on mesu.apple.com for updates. The updates are delivered in plain unencrypted ZIP files. On all recent iOS devices, iOS regularly checks on the availability of an update, and if one is available, will prompt the user to permit its automatic installation.
The latest stable version is iOS 14, released on September 16, 2020. It is available for iPhone 6S and later, and the seventh-generation iPod Touch.[173] In addition to the release of iOS 14, iPadOS 14 was released alongside iOS 14. Apple debuted iOS 14 and iPadOS 14 at its annual WWDC keynote on June 22, 2020.[174] iPadOS 14 is available on iPad Air 2 and later, iPad fifth-generation and later, iPad mini 4 and later and all versions of the iPad Pro.[175] The update introduced new features such as improved home screen widgets, the App Library, App Clips, and more.[176]
Originally, iPod Touch users had to pay for system software updates. This was due to accounting rules that designated it not a âsubscription deviceâ like iPhone or Apple TV, and improvements to the device required payments.[177][178] The requirement to pay to upgrade caused iPod Touch owners to stay away from updates.[179] However, in September 2009, a change in accounting rules won tentative approval, affecting Appleâs earnings and stock price, and allowing iPod Touch updates to be delivered for free.[180][181]
Apple has significantly extended the cycle of updates for iOS supported devices over the years. The iPhone (1st generation) and iPhone 3G only received two iOS updates, while later models had support for five to six years.[182][183]
XNU kernel
The iOS kernel is the XNU kernel of Darwin. The original iPhone OS (1.0) up to iPhone OS 3.1.3 used Darwin 9.0.0d1. iOS 4 was based on Darwin 10. iOS 5 was based on Darwin 11. iOS 6 was based on Darwin 13. iOS 7 and iOS 8 are based on Darwin 14. iOS 9 is based on Darwin 15. iOS 10 is based on Darwin 16. iOS 11 is based on Darwin 17. iOS 12 is based on Darwin 18. iOS 13 is based on Darwin 19.[184]
In iOS 6 the kernel is subject to ASLR, similar to that of OS X Mountain Lion. This makes exploit possibilities more complex since it is not possible to know the location of kernel code.
Since XNU is based on the BSD kernel, it is open source.[185] The source is under a 3-clause[186] BSD license for the original BSD parts, with parts added by Apple under the Apple Public Source License.[187] The versions contained in iOS are not available; only the versions used in macOS are available.
iOS does not have kernel extensions (kexts) in the file system, even if they are actually present. The kernel cache can be decompressed to show the correct kernel, along with the kexts (all packed in the __PRELINK_TEXT section) and their plists (in the __PRELINK_INFO section).
The kernel cache can also be directly decompressed (if decrypted) using third party tools. With the advent of iOS 10 betas and default plain text kernelcaches, these tools can only be used after unpacking and applying lzssdec to unpack the kernel cache to its full size.
The kextstat provided by the Cydia alternative software does not work on iOS because the kextstat is based on kmod_get_info(...), which is a deprecated API in iOS 4 and Mac OS X Snow Leopard. There are other alternative software that can also dump raw XML data.
On developing devices, the kernel is always stored as a statically linked cache stored in /System/Library/Caches/com.apple.kernelcaches/kernelcache which is unpacked and executed at boot.

In the beginning, iOS had a kernel version usually higher than the corresponding version of macOS. Over time, the kernels of iOS and macOS have gotten closer. This is not surprising, considering that iOS introduced new features (such as the ASLR Kernel, the default freezer, and various security-strengthening features) that were first incorporated and subsequently arrived on macOS. It appears Apple is gradually merging the iOS and macOS kernels over time. The build date for each version varies slightly between processors. This is due to the fact that the builds are sequential.
The latest version of the Darwin Kernel updated to iOS 13.6 is 19.6.0, dated July 27, 2020, while for iOS 14 beta 4 it is 20.0.0, dated July 27, 2020.

Kernel Image
The kernel image base is randomized by the boot loader (iBoot). This is done by creating random data, doing a SHA-1 hash of it and then using a byte from the SHA-1 hash for the kernel slide. The slide is calculated with this formula:
base=0x01000000+(slide_byte*0x00200000)
If the slide is 0, the static offset of 0x21000000 is used instead.
The adjusted base is passed to the kernel in the boot arguments structure at offset 0x04, which is equivalent to gBootArgs->virtBase.
Kernel Map
The kernel map is used for kernel allocations of all types (kalloc(), kernel_memory_allocate(), etc.) and spans all of kernel space (0x80000000â0xFFFEFFFF). The kernel based maps are submaps of the kernel_map, for example zone_map, ipc_kernel_map, etc.
The strategy is to randomize the base of the kernel_map. A random 9-bit value is generated right after kmem_init() which establishes kernel_map, is multiplied by the page size. The resulting value is used as the size for the initial kernel_map allocation. Future kernel_map (and submap) allocations are pushed forward by a random amount. The allocation is silently removed after the first garbage collection and reused. This behaviour can be overridden with the âkmapoffâ boot parameter.
Attacks
Kext_request() allows applications to request information about kernel modules, divided into active and passive operations. Active operations (load, unload, start, stop, etc.) require root access. iOS removes the ability to load kernel extensions. Passive operations were originally (before iOS 6) unrestricted and allowed unprivileged users to query kernel module base addresses. iOS6 inadvertently removed some limitations; only the load address requests are disallowed. So attackers can use kKextRequestPredicateGetLoaded to get load addresses and mach-o header dumps. The load address and mach-o segment headers are obscured to hide the ASLR slide, but mach-o section headers are not. This reveals the virtual addresses of loaded kernel sections.
This information leak has been closed with iOS 6.0.1.
Versions codenames
Internally, iOS identifies each version by a codename, often used internally only, normally to maintain secrecy of the project. For example, the codename for iOS 14 is Azul.
Jailbreaking
Since its initial release, iOS has been subject to a variety of different hacks centered around adding functionality not allowed by Apple.[188] Prior to the 2008 debut of Appleâs native iOS App Store, the primary motive for jailbreaking was to bypass Appleâs purchase mechanism for installing the App Storeâs native applications.[189] Apple claimed that it would not release iOS software updates designed specifically to break these tools (other than applications that perform SIM unlocking); however, with each subsequent iOS update, previously un-patched jailbreak exploits are usually patched.[190]
When a device is booting, it loads Appleâs own kernel initially, so a jailbroken device must be exploited and have the kernel patched each time it is booted up.
There are different types of jailbreak. An untethered jailbreak uses exploits that are powerful enough to allow the user to turn their device off and back on at will, with the device starting up completely, and the kernel will be patched without the help of a computer â in other words, it will be jailbroken even after each reboot.
However, some jailbreaks are tethered. A tethered jailbreak is only able to temporarily jailbreak the device during a single boot. If the user turns the device off and then boots it back up without the help of a jailbreak tool, the device will no longer be running a patched kernel, and it may get stuck in a partially started state, such as Recovery Mode. In order for the device to start completely and with a patched kernel, it must be âre-jailbrokenâ with a computer (using the âboot tetheredâ feature of a tool) each time it is turned on. All changes to the files on the device (such as installed package files or edited system files) will persist between reboots, including changes that can only function if the device is jailbroken (such as installed package files).
In more recent years, two other solutions have been created â semi-tethered and semi-untethered.
A semi-tethered solution is one where the device is able to start up on its own, but it will no longer have a patched kernel, and therefore will not be able to run modified code. It will, however, still be usable for normal functions, just like stock iOS. To start with a patched kernel, the user must start the device with the help of the jailbreak tool.
A semi-untethered jailbreak gives the ability to start the device on its own. On first boot, the device will not be running a patched kernel. However, rather than having to run a tool from a computer to apply the kernel patches, the user is able to re-jailbreak their device with the help of an app (usually sideloaded using Cydia Impactor) running on their device. In the case of the iOS 9.2-9.3.3 jailbreak, a Safari-based exploit was available, thereby meaning a website could be used to rejailbreak.
In more detail: Each iOS device has a bootchain that tries to make sure only trusted/signed code is loaded. A device with a tethered jailbreak is able to boot up with the help of a jailbreaking tool because the tool executes exploits via USB that bypass parts of that âchain of trustâ, bootstrapping to a pwned (no signature check) iBSS, iBEC, or iBoot to finish the boot process.
Since the arrival of Appleâs native iOS App Store, andâalong with itâthird-party applications, the general motives for jailbreaking have changed.[191] People jailbreak for many different reasons, including gaining filesystem access, installing custom device themes, and modifying SpringBoard. An additional motivation is that it may enable the installation of pirated apps. On some devices, jailbreaking also makes it possible to install alternative operating systems, such as Android and the Linux kernel. Primarily, users jailbreak their devices because of the limitations of iOS. Depending on the method used, the effects of jailbreaking may be permanent or temporary.[192]
In 2010, the Electronic Frontier Foundation (EFF) successfully convinced the U.S. Copyright Office to allow an exemption to the general prohibition on circumvention of copyright protection systems under the Digital Millennium Copyright Act (DMCA). The exemption allows jailbreaking of iPhones for the sole purpose of allowing legally obtained applications to be added to the iPhone.[193] The exemption does not affect the contractual relations between Apple and an iPhone owner, for example, jailbreaking voiding the iPhone warranty; however, it is solely based on Appleâs discretion on whether they will fix jailbroken devices in the event that they need to be repaired. At the same time, the Copyright Office exempted unlocking an iPhone from DMCAâs anticircumvention prohibitions.[194] Unlocking an iPhone allows the iPhone to be used with any wireless carrier using the same GSM or CDMA technology for which the particular phone model was designed to operate.[195]
Unlocking
Initially most wireless carriers in the US did not allow iPhone owners to unlock it for use with other carriers. However AT&T allowed iPhone owners who have satisfied contract requirements to unlock their iPhone.[196] Instructions to unlock the device are available from Apple,[197] but it is ultimately the sole discretion of the carrier to authorize the device to be unlocked.[198] This allows the use of a carrier-sourced iPhone on other networks. Modern versions of iOS and the iPhone fully support LTE across multiple carriers despite where the phone was originally purchased from.[199] There are programs to remove SIM lock restrictions, but are not supported by Apple and most often not a permanent unlock â a soft-unlock.[200]
A software unlock is the process by which the iPhone is modified such that the baseband will accept the SIM card of any GSM carrier. This is entirely different from a jailbreak; jailbreaking oneâs iPhone does not unlock it. A jailbreak is, however, required for all currently public, unofficial software unlocks.
The legality of software unlocking varies in each country; for example, in the US, there is a DMCA exemption for unofficial software unlocking, but the exemption is limited to devices purchased before January 26, 2013 (so software unlocks for newer devices are in a legal grey area).[201]
Digital rights management
The closed and proprietary nature of iOS has garnered criticism, particularly by digital rights advocates such as the Electronic Frontier Foundation, computer engineer and activist Brewster Kahle, Internet-law specialist Jonathan Zittrain, and the Free Software Foundation who protested the iPadâs introductory event and have targeted the iPad with their âDefective by Designâ campaign.[202][203][204][205] Competitor Microsoft, via a PR spokesman, criticized Appleâs control over its platform.[206]
At issue are restrictions imposed by the design of iOS, namely digital rights management (DRM) intended to lock purchased media to Appleâs platform, the development model (requiring a yearly subscription to distribute apps developed for the iOS), the centralized approval process for apps, as well as Appleâs general control and lockdown of the platform itself. Particularly at issue is the ability for Apple to remotely disable or delete apps at will.
Some in the tech community have expressed concern that the locked-down iOS represents a growing trend in Appleâs approach to computing, particularly Appleâs shift away from machines that hobbyists can âtinker withâ and note the potential for such restrictions to stifle software innovation.[207][208] Former Facebook developer Joe Hewitt protested against Appleâs control over its hardware as a âhorrible precedentâ but praised iOSâs sandboxing of apps.[209]
Security and privacy
iOS utilizes many security features in both hardware and software. Below are summaries of the most prominent features.
Secure Boot
Before fully booting into iOS, there is low-level code that runs from the Boot ROM. Its task is to verify that the Low-Level Bootloader is signed by the Apple Root CA public key before running it. This process is to ensure that no malicious or otherwise unauthorized software can be run on an iOS device. After the Low-Level Bootloader finishes its tasks, it runs the higher level bootloader, known as iBoot. If all goes well, iBoot will then proceed to load the iOS kernel as well as the rest of the operating system.[210]
Secure Enclave
The Secure Enclave is a coprocessor found in iOS devices part of the A7 and newer chips used for data protection, Touch ID and Face ID. The purpose of the Secure Enclave is to handle keys and other info such as biometrics that is sensitive enough to not be handled by the Application Processor (AP). It is isolated with a hardware filter so the AP cannot access it. It shares RAM with the AP, but its portion of the RAM (known as TZ0) is encrypted. The secure enclave itself is a flashable 4MB AKF processor core called the secure enclave processor (SEP) as documented in Apple Patent Application 20130308838. The technology used is similar to ARMâs TrustZone/SecurCore but contains proprietary code for Apple KF cores in general and SEP specifically. It is also responsible for generating the UID key on A9 or newer chips that protects user data at rest.[211]
It has its own secure boot process to ensure that it is completely secure. A hardware random number generator is also included as a part of this coprocessor. Each deviceâs Secure Enclave has a unique ID that is given to it when it is made and cannot be changed. This identifier is used to create a temporary key that encrypts the memory in this portion of the system. The Secure Enclave also contains an anti-replay counter to prevent brute force attacks.[210]
The SEP is located in the devicetree under IODeviceTree:/arm-io/sep and managed by the AppleSEPManager driver.[212]
Face ID
Face ID is a face scanner that is embedded in the notch on iPhone models X, XS, XS Max, XR, 11, 11 Pro, 11 Pro Max, 12, 12 Mini, 12 Pro, and 12 Pro Max. It can be used to unlock the device, make purchases, and log into applications among other functions. When used, Face ID only temporarily stores the face data in encrypted memory in the Secure Enclave, as described below. There is no way for the deviceâs main processor or any other part of the system to access the raw data that is obtained from the Face ID sensor.[210]
Passcode
iOS devices can have a passcode that is used to unlock the device, make changes to system settings, and encrypt the deviceâs contents. Until recently, these were typically four numerical digits long. However, since unlocking the devices with a fingerprint by using Touch ID has become more widespread, six-digit passcodes are now the default on iOS with the option to switch back to four or use an alphanumeric passcode.[210]
Touch ID
Touch ID is a fingerprint scanner that is embedded in the home button and can be used to unlock the device, make purchases, and log into applications among other functions. When used, Touch ID only temporarily stores the fingerprint data in encrypted memory in the Secure Enclave, as described above. There is no way for the deviceâs main processor or any other part of the system to access the raw fingerprint data that is obtained from the Touch ID sensor.[210]
Address Space Layout Randomization
Address Space Layout Randomization (ASLR) is a low-level technique of preventing memory corruption attacks such as buffer overflows. It involves placing data in randomly selected locations in memory in order to make it more difficult to predict ways to corrupt the system and create exploits. ASLR makes app bugs more likely to crash the app than to silently overwrite memory, regardless of whether the behavior is accidental or malicious.[213]
Non-Executable Memory
iOS utilizes the ARM architectureâs Execute Never (XN) feature. This allows some portions of the memory to be marked as non-executable, working alongside ASLR to prevent buffer overflow attacks including return-to-libc attacks.[210]
Encryption
As mentioned above, one use of encryption in iOS is in the memory of the Secure Enclave. When a passcode is utilized on an iOS device, the contents of the device are encrypted. This is done by using a hardware AES 256 implementation that is very efficient because it is placed directly between the flash storage and RAM.[210]
iOS, in combination with its specific hardware, uses crypto-shredding when erasing all content and settings by obliterating all the keys in âeffaceable storageâ. This renders all user data on the device cryptographically inaccessible.[214]
Keychain
The iOS keychain is a database of login information that can be shared across apps written by the same person or organization.[210] This service is often used for storing passwords for web applications.[215]
App Security
Third-party applications such as those distributed through the App Store must be code signed with an Apple-issued certificate. In principle, this continues the chain of trust all the way from the Secure Boot process as mentioned above to the actions of the applications installed on the device by users. Applications are also sandboxed, meaning that they can only modify the data within their individual home directory unless explicitly given permission to do otherwise. For example, they cannot access data owned by other user-installed applications on the device. There is a very extensive set of privacy controls contained within iOS with options to control appsâ ability to access a wide variety of permissions such as the camera, contacts, background app refresh, cellular data, and access to other data and services. Most of the code in iOS, including third-party applications, runs as the âmobileâ user which does not have root privileges. This ensures that system files and other iOS system resources remain hidden and inaccessible to user-installed applications.[210]
App Store bypasses
Companies can apply to Apple for enterprise developer certificates. These can be used to sign apps such that iOS will install them directly (sometimes called âsideloadingâ), without the app needing to be distributed via the App Store.[216] The terms under which they are granted make clear that they are only to be used for companies who wish to distribute apps directly to their employees.[216]
Circa JanuaryâFebruary 2019, it emerged that a number of software developers were misusing enterprise developer certificates to distribute software directly to non-employees, thereby bypassing the App Store. Facebook was found to be abusing an Apple enterprise developer certificate to distribute an application to underage users that would give Facebook access to all private data on their devices.[217][218][219] Google was abusing an Apple enterprise developer certificate to distribute an app to adults to collect data from their devices, including unencrypted data belonging to third parties.[220][216] TutuApp, Panda Helper, AppValley, and TweakBox have all been abusing enterprise developer certificates to distribute apps that offer pirated software.[221]
Network Security
iOS supports TLS with both low- and high-level APIs for developers. By default, the App Transport Security framework requires that servers use at least TLS 1.2. However, developers are free to override this framework and utilize their own methods of communicating over networks. When Wi-Fi is enabled, iOS uses a randomized MAC address so that devices cannot be tracked by anyone sniffing wireless traffic.[210]
Two-Factor Authentication
Two-factor authentication is an option in iOS to ensure that even if an unauthorized person knows an Apple ID and password combination, they cannot gain access to the account. It works by requiring not only the Apple ID and password, but also a verification code that is sent to an iDevice or mobile phone number that is already known to be trusted.[210] If an unauthorized user attempts to sign in using another userâs Apple ID, the owner of the Apple ID receives a notification that allows them to deny access to the unrecognized device.[222]
Reception
iOS is the second most popular mobile operating system in the world, after Android. Sales of iPads in recent years are also behind Android, while, by web use (a proxy for all use), iPads (using iOS) are still the most popular.[223]
By the middle of 2012, there were 410Â million devices activated.[224] At WWDC 2014, Tim Cook said 800Â million devices had been sold by June 2014.[225]
During Appleâs quarterly earnings call in January 2015, the company announced that they had sold over one billion iOS devices since 2007.[226][227]
By late 2011, iOS accounted for 60% of the market share for smartphones and tablets.[228] By the end of 2014, iOS accounted for 14.8% of the smartphone market[229] and 27.6% of the tablet and two-in-one market.[230] In February 2015, StatCounter reported iOS was used on 23.18% of smartphones and 66.25% of tablets worldwide, measured by internet usage instead of sales.[231]
In the third quarter of 2015, research from Strategy Analytics showed that iOS adoption of the worldwide smartphone market was at a record low 12.1%, attributed to lackluster performance in China and Africa. Android accounted for 87.5% of the market, with Windows Phone and BlackBerry accounting for the rest.[232][233]

Apple watchOS 7 preview
Of the big three Apple operating systems, watchOS arguably gets the least love. That goes double in a year that sees macOS getting its biggest overhaul in recent memory. On the whole, the Apple Watchâs software is often overlooked, as smartwatch users tend to focus attention on the addition of new hardware sensors and the like. Still, watchOS 7, out today in public beta, brings a number of key additions, as Apple looks to keep from getting too complacent in its spot high atop the list of smartwatch manufacturers.
After all, the company has seen increased competition, particularly overseas from the likes of Huawei and Samsung. Likely software updates alone arenât enough to drive the smartwatch skeptics to finally take the dive, but coupled with hardware updates and a focus on keeping lower-cost models on the market, it should help the company maintain comfortable positioning.
iOS 13 brings many much needed quality-of-life improvements
Updates include the new hand-washing featuring, cycling directions, new workouts and, most importantly, a number of sleep-tracking features. The last bit is, without question, the most requested addition to the watch â and equally important to Appleâs bottom line, a category the company had fallen behind on relative to the competition. Thatâs not for lack of available technology, however. The sleep tracking here works with the sensors already on-board existing devices and joins a number of third-party solutions.
Image Credits: Brian Heater
Thatâs not to say that the company wonât be introducing additional sleep-tracking hardware on the Watch 6 later this year (in fact, that seems fairly likely), but it does mean that the much-requested feature will be available for the Watch Series 5, 4 and 3, which debuted back in late-2017 and is still kicking around the market, priced at $200.
The Sleep feature is multi-faceted. At its core, of course, is standard tracking, using the accelerometer to determine when youâve fallen asleep, based on movement, including subtler cues like changes in breathing rate, which slows down as you enter non-REM sleep. Stats arenât super deep yet, but do include key information like sleep times and heart rate, all saved in Appleâs Health app.
macOS 11.0 Big Sur preview
One of the more salient pieces of the puzzle is Sleep Mode, in which the watch enters Do Not Disturb, shutting off all notification and pausing the wake function when the wrist is lifted. You can turn it off by turning the digital crown and it will re-enter the mode when you fall back asleep.
Among other things, it should help save on battery life â thatâs going to be a key issue as the company gets serious about sleep. The Watch is currently rated at 18 hours, by Appleâs account, which is an issue if you plan to use it for tracking both day and night. Extended battery is another feature to keep an eye out for with the arrival of the Series 6, but in the meantime, a new Charging reminder will pop up when you wake up, reminding you to charge the watch before you get going. It will also alert you if the level falls below 30% prior to sleeping.
Apple began work on the Watchâs handwashing feature years before COVID-19
The other big element is Sleep Schedule, which sets a goal and a sleep and wake time. By default, itâs set to eight hours â which feels overly optimistic in my own experience, but thatâs the point of goals, I guess. Wind Down creates a window of time for pre-sleep activities, like meditation apps and soundscapes, designed to get you off your devices and ready for bed. Wake Up, meanwhile, borrows sounds from iOSâs Bedtime app and uses haptic feedback as an alarm. If youâre moving half-an-hour before your set wake time (the worst), it will ask you if youâd like to shut off the alarm and just start your day.
Image Credits: Brian Heater
Hand washing is a serendipitous addition here. As I noted in an earlier feature, itâs something the company has been working on for years now, and happened to arrive when everyone is hyper-focused on keeping their hands clean. The feature is off by default and needs to be enabled by the user. Once on, it starts a 20-second count with animated bubble numbers and gives you a little congratulatory buzz when youâve washed them the whole time.
Itâs designed to automatically trigger when hand washing is detected through a combination of movement sensed by the accelerometer and the on-board microphone, which is listening for the sound of running water and soap. Apparently detecting hand washing is surprisingly complicated, but the feature does a pretty decent job in this version of the beta â though I did still get a few false positives while washing the dishes.
The other key addition is hand-washing reminders, which can be set to pop up when you arrive at home. Again, a nice addition in an error with a super contagious, air and surface-borne virus currently rampaging across the globe. Hand washing doesnât have its own standalone app at the moment, but metrics for the feature are built directly into the health app, showing your activity over time.
There are four new workout types now tracked by the OS: dance, core training, functional strength training and cool down, which involves stretches and other post-workout activities. The additions are a bit more in the weeds than early tracking features, as Apple works to position the wearable as a more complete fitness tracker. The accompanying iOS app also gets a redesign, consolidating all of the activities into a single view.
As ever, there are a couple of new watch faces. Chronograph Pro adopts a design inspired by a distance-measuring tachymeter. Itâs a bit busy for my tastes, but itâs not a bad-looking design. The X-Large takes things in the opposite direction, with just a large digital time and a massive complication right in the center of the screen. Also new on the face front is the ability to share Watch Faces with friends via text message.
Image Credits: Brian Heater
The coolest addition here might very well be one that didnât get a lot of stage time. Along with the other operating systems, watchOS gets a translate feature. Click into Siri, ask for a translation and then pick from one of the following: Arabic, German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Russian and Chinese (Mandarin). Speak the words and it will read aloud the translation and show it on the screen. In case of a language like Chinese with a distinct alphabet, the text will be displayed in both Chinese and an English transliteration.
The process requires a few steps, but as someone who spent a lot of time handing his phone back and forth to people during a trip to Asia last year, this could be really useful. Especially during a time when I really have no desire to hand my phone to anyone.
A handful of other features warrant a quick mention:
Cycling directions for Apple Maps
Increased Hearing Health/Noise metrics and the ability to control maximum volume on headphones
Siri Shortcuts imported from the iPhone
The final version of watchOS 7 is due out this fall.

The latest UI comes up with improved gesture functioning, all the actions will be smoother and way better than the previous ones. The most specific change is in the gesture navigation now it follows the stock Android 10 approach. There is a new AOD (always-on-display) and floating window feature, due to which you can always keep app-previews open over the full-screen content.
New Quick Settings
A huge improvement is also seen in the notification management of the system and now user can enjoy its new quick reply feature.
Live Wallpapers
Live wallpapers will be the most fascinating feature of the MIUI 12, live wallpapers will come up with different background animations and several other features, it gives neat visual features in which it will zoom in from a space view to an aerial shot each time you unlock your phone.
Dark Mode 2.0
Dark Mode 2.0 will make the drastic and amazing change, this is another impressive feature, "Wallpaper Dimming" in which you can dynamically adjust the color temperature of the wallpaper and Xiaomi has also worked upon readability of the text, so with new UI you can adjust the font size of the system for better reading experience and reducing eye-strain.
Global Free Window
Xiaomi has increased the capability of the small screen window, by which you can reply to a text while playing games, or watching any video. Till now before MIUI 12, if a message has arrived while playing any game, we slide down the window on the notification bar and then reply, but with the new update, you can drag it to the top right corner and can see a tiny screen all the time.
Mi Health
With the MIUI 12, Mi health app is also released officially, now you can have a track of total steps, sleep, workout, and many more things, just by keeping your phone on. You will be able to see that all the data of your running, walking, working, etc. is being recorded by the app. This app also able to monitor your sleep, without a fitness tracker, you will need to place your phone with you or on your pillow while sleeping. Mi health app is much beneficial to the female users too it sends sluggish reminders to record their menstrual cycles.

Privacy Enhancements
Xiaomi has adopted a three-pronged strategy to improve privacy features. This strategy includes Flare, Barbed Wire, and the Mask System.

Flare, will keep an eye on the behavior of all apps that are present in your phone and provide you a list of all apps that are taking your privacy to the risk and disobeying the permissions. It will also offer you suggestions for improving your privacy.
Barbed Wire, it is built upon the privacy improvements of Android 10, in Android 10 while permitting any app, we choose "always allow" option for allowing the app to access the camera and location, etc. But with MIUI 12 you won't be able to see the "always allow" button if the app does not specify why it requires permission.
The Mask System, this feature lets the user create and share virtual ID on apps, similar features are already seen in Apple iOS 13 and Color OS 7. This feature will provide more control of the owner over the data.
Xiamoi's beta testing is now closed, but live for Chinese users, and the stable version is supposed to be released in June. These dates are according to Chinese standards, while international dates may vary. All of us are eagerly waiting for the stable update; so, we can explore the latest user interface MIUI 12 announced by Xiaomi.
