iOS 11 is the eleventh release of iOS mobile operating system developed by Apple Inc., being the iOS 10 successor. It was announced at the Worldwide Worldwide Developer Conference on June 5, 2017, and was released on September 19, 2017.
Among iOS 11 changes: lock screen and Notification Center are merged, allowing all notifications to be displayed directly on the lock screen. The Control Center pages are unified, getting custom settings and capabilities for the 3D Touch icon for more options. The App Store receives a visual overhaul to focus on editorial content and daily highlights. File manager application "File" allows direct access to files stored locally and in cloud services. Siri can now translate between languages ​​and use privacy-minded "learning on device" techniques to better understand user interests and offer suggestions. The camera has a new setting to enhance portrait mode photos and will use the new encoding technology to reduce the file size on newer devices. In future releases, Messages will be integrated with iCloud to sync better messages on iOS and macOS devices. The previous point release also added support for Apple Pay-to-person payments. The operating system also introduces the ability to record screens, limited drag-and-drop functionality, and support for augmented reality. Certain new features will only appear on iPads, including always-accessible dock apps, drag-and-drop cross-apps, and new user interfaces to show multiple apps at once.
iOS 11 receives mixed reviews. Critics significantly praised dock applications and the new multitasking interface on iPad, citing them for updating the user experience. Further praise is directed at the redesigned Control Center that offers customized turns, despite being criticized for lack of third party application support, lack of Wi-Fi network selection capabilities and for difficult use on small screen sizes, along with instability. Critics also noted a new augmented reality development tool, but said the impact would depend on third-party applications and how quickly developers embraced them. Praise is also directed at redesigning the App Store and new file management tools. Shortly after the release, it was found that disabling Wi-Fi and Bluetooth connections through the Control Center did not disable the chips present in the device in order to keep functioning for background connectivity, design decisions that triggered criticism for "misleading" users and reduced security. because of potential vulnerabilities in open connections that are not active. The iOS 11.2 update adds new warning messages and toggle colors to explain new functions. iOS 11 also receives constant criticism from critics and end users because of perceived stability and performance issues, especially on older devices; Apple has issued many software updates to address the issue and has dedicated iOS 12 primarily for stability and performance improvements.
Two months after release, 52% of iOS devices run iOS 11, a slower adoption rate than previous iOS versions. The number increased to 81% of devices in May 2018.
On June 4, 2018, at Worldwide Worldwide Developer Conference, Apple announced its successor, iOS 12.

System features
Lock screen
The lock screen and Notification Center are merged, allowing users to view all live notifications on the lock screen. Scrolling up and down will show or hide notifications.
Control Center
The Control Center redesign unites its pages and allows users to touch 3D buttons (or long press on devices without 3D Touch) for other options. Slider adjusts volume and brightness. The Control Center can be customized through the Settings app, and allows more settings to be displayed, including mobile services, Low Power Mode, and shortcuts to Notes apps.
Siri
Smart personal assistants from Siri have a more humane voice and support language translation, with English, Chinese, French, German, Italian and Spanish available at launch. It will also support follow-up questions by users. Users can also type into Siri.
Siri will be able to use "device learning", a privacy-minded local learning technique to understand user behavior and interests within different apps, to offer better recommendations and recommendations.
Settings
The new "Do Not Disturb When Driving" mode lets users block unnecessary notifications as long as their iPhone is connected to a vehicle via Bluetooth. The auto-reply feature sends a specific reply to a message sender to let them know that the current user is not available via text. Passengers can be granted full notification access to the phone.
The new "Smart Invert" feature, dubbed "dark mode" by several publications, reverses colors on the screen, except for images, some apps, and some user interface elements. Using iPhone X, which uses OLED technology, some news channels report that this feature can save battery life by turning off pixels when black, saving energy by preventing it from displaying white pixels.
Users gain extended control over the usage of the app's location, with each app displaying a "Temporary Using App" switch in Settings. This is different from previous iOS versions, where apps are only required to have "Never" or "Always" location options.
Users can delete less used apps without losing app data using the "Offload App" button. This allows reinstalling the app later (if available in the App Store), where data return and usage can continue. Users can also remove the app automatically with the "Offload Uninstalled Apps" setting. When the app is downgraded, the app will appear on the home screen as a gray icon.
Personalized suggestions help users free up space on their devices, including empty Photos, back up messages, and enable iCloud Photo Library to back up photos and videos.
iPad
A number of new iOS 11 features will only appear on iPad. The app dock underwent a reshuffle, bringing it closer to the design seen on macOS, and accessible from any screen, allowing users to more easily open apps in a separate screen view. Users can also drag-and-drop files across various applications. The new multitasking interface displays multiple apps on screen at the same time in a floating "window." In addition, through a combination of "slide over", "split view", and "picture-in-picture" modes, users can have up to four active apps on the screen at the same time.
Each letter on the iPad keyboard displays an alternate background number or symbol, accessible by pulling down on the button and releasing each one.
The Control Center is visible in the multitasking window on the iPad.
Running iOS 11, the 9.7-inch, 10.5-inch, and 2nd-generation 12.9-inch iPad Pros now have flash support.
Camera
iOS 11 introduces optical image stabilization, flash photography, and high dynamic range for portrait photos.
Live Photos accepts new "Loop", "Bounce" and "Long Exposure" effects, and uses the High Efficiency Image File Format to reduce photo size.
On devices with Apple A10 or newer chips, photos can be compressed in the new High Efficiency Image File Format and video can be encoded in the Video Coding High Efficiency video compression format, which enables quality improvement while also reducing the size by half.
Wallpaper
Apple significantly changed the available wallpapers for use with iOS 11. In the early beta version, released after Apple's developer conference, Apple included a new wallpaper, and erased all six live "Live" animated fish wallpapers, introduced with iPhone 6S in 2015. Release iOS 11.2 then brings the iPhone X/8/8 Plus-exclusive wallpaper to the older iPhone.
iPhone X exclusively featured six "Live" wallpapers and seven new "Dynamic" wallpapers.
Other changes
iOS 11 introduces native support for QR code scans, via the Camera app. Once the QR code is positioned in front of the camera, a notice is made offering suggestions for action based on the scanned content. Twitter users have so far discovered that joining a Wi-Fi network and adding someone to the contact list is supported via a QR code.
Third party keyboard can add one-handed mode.
Users can record screen natively. To record the screen, the user must first add the feature to the Control Center via the Settings app. Once added, the user can start and stop the recording from a special Control Center icon, with a clear-colored bar appearing at the top of the screen that shows the active recording. Pressing the bar gives you the option to end the recording, and the video is saved to the Photos app.
When an iOS 11 device tries to connect to a Wi-Fi network, a nearby Sierra Sierra iOS 11 or macOS device can wirelessly send passwords, simplifying the connection process.
The overlay change volume no longer covers the screen while playing the video, and a smaller scrubber appears at the top right of the screen.
After a user takes a screenshot, a screenshot thumbnail will appear on the bottom left of the screen. Users can then tap a thumbnail to bring up an interface that allows them to crop, annotate, or delete screenshots.
Third-party apps can also use iCloud Key Chain to allow automatic password clearance.
Flight airline flight information can be viewed in Spotlight via custom widgets.
iOS 11 replaces the left-top mobile network power icon from five dots to four signal bars, similar to before iOS 7.

Similar to iPad, drag-and-drop file support is available on iPhone, although with more restrictions, especially supported only within the app, not between.
Many Apple pre-installed apps, including Notes, Contacts, Reminders, Maps, and the App Store, have redesigned the home screen icon.
The "Emergency SOS" feature is added, which disables Touch ID after pressing the Sleep/Wake button five times in a row. This prevents the Touch ID from working until the iPhone password is entered.
iOS 11 adds support for 8-bit and 10-bit HEVC. Devices with Apple A9 chip or hardware hardware decoding are newer, while older devices support software-based decoding.
App features
Where there is free space in the Mail app, users can draw inline.
Message
The Messages app syncs messages on iOS and macos via iCloud, which reflects deleting messages across devices. This feature was temporarily removed in the fifth beta release and returned on May 29, 2018 when iOS 11.4 was released.
At the time of iOS 11 announcement in June 2017, Apple delivered functionality that allows users to send person-to-person payments with Apple Pay via Messaging. At the iOS 11 launch in September 2017, the feature did not exist, was removed in the previous beta, with Apple announcing the feature as "coming this fall with an update for iOS 11". Launched a few days after iOS 11.2 update aired, although initially only available in the United States.
A new app drawer for iMessage app aims to simplify the experience of using apps and stickers, and an optimized storage system reduces the size of the message backup.
The Messages app also combines the "Business Chat" feature for businesses to communicate directly with customers through the app. This can be accessed via the message icon next to the business search results. However, this feature is not included with the initial release of iOS 11 (instead launched with iOS 11.3).
The Messaging app on iPhone X introduces a facial tracking emoji called "Animoji" (emoji animation), using Face ID.
App Store
The App Store received a complete redesign, with a greater focus on editorial content such as daily highlights, and designs described as "cleaner and more consistent" for other apps developed by Apple. The design of the app mimics the design seen in the Apple Music app on iOS 10.
Maps
In certain locations, Apple Maps will offer indoor maps for shopping and airports.
New line instructions and speed limit features aim to guide drivers on unfamiliar roads.
Photos
The Photos app on iOS 11 gets support for viewing GIF animations. Users can access GIF images in an album titled "Animated".
Memories can be viewed when the phone is in portrait orientation.
Podcasts
The Podcast app receives a redesign similar to the App Store, focusing on editorial content.
Note
The Notes app has an internal document scanner using device cameras, and this feature removes artifacts such as glare and perspective.
The "Instant Notes" feature on iPad Pro allows users to start writing notes from the lock screen by putting an Apple Pencil onto the screen.
The application also allows users to insert inline tables.
Where there is open space in the Notes app, users can draw inline.
File
The new "Files" app lets users search for files stored on their devices, as well as those stored in various cloud services, including iCloud Drive, Dropbox, OneDrive, and Google Drive. The app supports organizations through structured sub-folders and various file-based options. The "File" app also includes a default player for FLAC audio files. The Files app is available on iPad and iPhone.
Safari
User flight information can be found in the Safari app.
Developer API
The new "ARKit" application programming interface (API) allows third-party developers to build augmented reality apps, utilizing device cameras, CPUs, GPUs, and motion sensors. The ARKit function is only available to device users with Apple A9 and newer processors. According to Apple, this is because "this processor provides breakthrough performance that enables fast scene understanding and lets you build detailed and engaging virtual content above real-world scenes."
The new "Core ML" software framework will speed up application tasks that involve artificial intelligence, such as image recognition.
The new "Depth" API allows third-party camera app developers to take advantage of iPhone 7 Plus, iPhone 8 Plus, and iPhone X's dual-camera "Portrait mode". This will let the app apply the same depth sensing technology available in the default iOS Camera app, to simulate shallow depths.
The new "NFC Core" framework gives developers limited access to near field IP communications chips (NFCs) within supported iPhone, opening up possible use cases where apps can scan for nearby environments and provide more information to users.
Deleted function
Applications should be compiled for 64-bit architectures to be supported on iOS 11. 32-bit applications are not supported or displayed in the App Store on iOS 11, and users who try to open the app receive alerts about application mismatch.
iOS 11 dropped the original system integration with Twitter, Facebook, Flickr, and Vimeo.
The iCloud Drive app is deleted and replaced by the Files app.
The ability to trigger multitasking using 3D Touch has been removed from the original iOS 11 release. In response to a bug report, an Apple engineer wrote that "Please know that this feature is intentionally deleted". The head of Apple's software engineering, Craig Federighi, replied to an email that the company had to "suspend support" due to "technical obstacles", promising to bring it back in the future for the iOS 11 update. It was brought back to iOS 11.1.
On iOS 11.2 the toggle buttons for Wi-Fi and Bluetooth are unexpectedly changed to not completely shut down both but temporarily until the next day. The actual shut off is in the Settings app.
Reception
Dieter Bohn from The Verge loves the new Control Center settings, including customizable snaps and 3D options Expandable touch, writes that "there are some panels I greatly admire," specifically highlighting Apple Remote TV as possible replacement from a normal remote. He, however, noted the lack of third-party access to the Control Center, in the hope for future support, and the lack of Wi-Fi network selection capabilities. He praised the screen recording function, calling it "super neat". Bohn strongly criticized the notification's view, writing that he had a "very serious dispute" with Apple about managing it, explaining that he preferred to use the screen as much as possible while stating that "Apple's philosophy is that I try way too hard" to control that notification fast. Bohn loves the new File app, new drag-and-drop functionality on the home screen that lets users drag many apps at once, and significantly praises multitasking on iPad. Writing that "Multitasking on an iPad is a near-disclosure experience", it enjoys docking applications and the ability to place up to three apps on the screen at once with more freedom on placement. Bohn acknowledges that "It's not as easy and simple as or [ sic ] because it's easily manipulated as a traditional windowing system like you would use a Mac, PC or Chromebook," but still praises it for being "radically more powerful than ever on the previous iPad". Finally, Bohn praised Siri for sound improvements, highlighting augmented reality that allows for "amazing games", and reaffirms previous sentiments that iOS 11 was "the most ambitious software update from Apple in a very, very long time".
Macworld ' s Jason Snell writes that the hype surrounding iOS 11 "is justified". Snell hailed the new data transfer mode and smoother new settings between the old iPhone and the new iPhone, referring to previous experience doing it manually as "a frustrating exercise in entering passwords repeatedly while tapping a long series of questions about enabling or disabling many iOS features". He also praised the Control Center design, calling it a "major upgrade", although it also highlighted the inability to easily switch to Wi-Fi networks. Snell noted that the App Store's design has not changed for years, but received a full redesign on iOS 11, and wrote that Apple's commitment to editorial pages is "impressive", making the App Store "a richer, more enjoyable experience." Regarding the introduction of augmented reality, it states that most applications that use it are "bad", although some are also "amazingly good", adding that "great potential" depends on how third-party apps use them. Snell also praised the upgrading of the iPad experience, including multitasking and drag-and-drop across apps, the latter of which he stated "really surpassed my expectations" due to ease of use. Its summary states that iOS 11 is "Apple's most ambitious and impressive upgrade in years".
Romain Dillet from TechCrunch mostly focuses on the iPad in its review, writes that iOS 11 "turns your iPad into a completely different machine", with multitasking "much more efficient" and improved accessibility with dock applications. He also praised the App Store design overhaul, calling it "a big improvement over the previous App Store", and also highlighting design changes in other apps, including "big thick headers with app or section names." Although he acknowledged that "Many technology friends have told me that they hate this change," Dillet stated that "I think most people will love it.This is visually fun and distinctive." He stated that augmented reality would become more relevant in the days following the release of iOS 11 as third-party developers incorporating features into their apps, and praised Apple for creating the ARKit development tool because it "made it easier to implement augmented reality features". In conclusion, Dillet writes that "Ten years ago, iOS started as a constrained operating system, now one of the largest digital playgrounds."
Devindra Hardawar from Engadget states that the focus of iOS 11 is "all about turning iOS into something more like a desktop", with many improvements to the iPad while "leaving the iPhone a bit behind". He has mixed feelings about the Control Center, writing that, on the size of a small mobile screen, it "feels like a jumble of mess," and adds that true comfort may only come with a bigger screen, a nuisance situation for non-Plus device owners. However, he praised the ability to customize buttons, including deleting which was never used by the user, and the ability to record screens quickly or enable accessibility features. He calls the new app design "interesting", and better shows a new app drawer at the bottom of the conversation in the Messages app, referring to it as "a major improvement over last year's messy interface". He praised Siri for improving the sound, Photos app to create better Memories, and new social features on Apple Music, although noting the lack of people in their social circle using the service. Referring to IKEA's "IKEA Place" application, which uses augmented reality to locate objects virtually in a room, he significantly praised the performance of enlarged reality technology on the iPhone, writing that "It does an excellent job of rendering furniture in physical space using both iPhone 8, and, even more impressive, it runs smoothly on my iPhone 6S ". Finally, Hardawar also enjoys new functionality on the iPad, calling multitasking, dock apps and drag-and-drop "dramatic changes", and highlights the "very useful" experience of dragging Internet content directly from the web to the new Files app. In summary, he acknowledged a significant step made for the iPad with iOS 11, writes that "it's a shame that iOS 11 does not bring more to the table on the iPhone", despite recognizing the emergence of augmented reality.
In November 2017, Apple App Store support pages updated to reflect that 52% of iOS devices run iOS 11, a slower rate of migration than for iOS releases 10 years earlier, which saw 60% of users adopted in October 2016. The number increased to 59 % of devices in December 2017.
Designing inconsistencies and software bugs
In September 2017, Jesus Diaz of Fast Company criticized design details on iOS 11 and Apple's native apps that did not follow Apple's user interface guidelines. Headers are not aligned correctly between different applications, unconstrained elements, and different colors and sizes causing Diaz to write that "When it comes to software, Apple's attention to detail will collapse". However, he also looked back in history, mentioning that the original design of Apple Music, the lack of alignment of optical typography in the Calendar app, and the improved iOS design faults previously ported to the macOS software have determined that "This inconsistency and lack of detail is not new at Apple ". He firmly stated: "This may be inevitable, given the monumental task of having to update the operating system every year, but for companies that claim to have an obsessive attention to detail, this is unacceptable".
In November 2017, Adam Clark Estes wrote extensively about software bugs and product imperfections experienced while using iOS 11. Estes pointed out issues such as a keyboard that covered the message and disappears the reply field in the Messages app, the letter "i" turns into a Unicode symbol, and the screen becomes unresponsive, writes that "The new operating system has turned my phone into a bug-infested carcass of a previous self, and the frustration of trying to use it sometimes makes me want to die too ". He also writes about the technological aspects of being more sophisticated and sophisticated, explaining that "back when the iPhone 4 came out [...] the smartphone is much simpler.The cameras are happily ugly The screen is small The number of applications we can download and stuff which we can relate to be trivial compared to today. [...] We should expect some bugs, I think. The more complex pieces of technology contain more points of failure, and I over-simplify this problem. "He concludes by theorizing on technological developments , however, I tried to understand how my life with computers changed dramatically from the days of Windows 95 when nothing worked so well, into the golden age of iPhone 4 when everything seemed perfect, for now when only a few iOS bugs make I feel like the world is a mess. [...] Maybe I am the annoying, crybaby person who is annoyed because no one is tam pack perfectly again. Or maybe, just maybe, Apple is slipping, and we are wrong to believe everything ".
Problem
Wi-Fi and Bluetooth Control Center Switch
Shortly after iOS 11 was released, the Representative ' s Motherboard found a new behavior by Wi-Fi and Bluetooth turned off in the Control Center. When the user taps to turn off the feature, iOS 11 only disconnects the chip from the active connection, but does not disable the individual chips on the device. The report further states that "it is a feature, not a bug", the reference page documentation by Apple confirms the behavior of the new switch as a means to disconnect from connection but remain active for AirDrop transfers, streaming AirPlay, Apple Pencil input, handoff and other features.. Security researcher Andrea Barisani told Motherboard that the new user interface is "not clear at all", making the user experience "more uncomfortable". In October 2017, the Electronic Frontier Foundation published articles, calling the interface "misleading" and "bad for user safety", because of the risk of higher security vulnerabilities with Wi-Fi and Bluetooth chips being enabled when not in active use. The Foundation recommends that Apple fix the "gap in connectivity", writing that "It's just a matter of better communicating to users, and giving them control and clarity when they want the settings turned off - not" off-ish ".
iOS 11.2 modifies this behavior slightly, by turning the white color off and displaying a warning message explaining the shutdown function in the Control Center, when the power off is turned off.
Battery drain issue
Some users have experienced battery drain problems after updating to iOS 11. In a poll on its website, 70% of 9to5Mac users reported a decrease in battery life after updating to the new operating system. However, in an article featuring a Twitter battery life complaint, Daily Express writes that "honestly, this is indeed expected.It happens every year, and it's completely normal.Music releases will hammer your device's battery much faster during the first few days of use ", with Forbes stating in the article that" A few days after you install the new version of iOS, your iDevice is busy doing a variety of cleanup.Practically all your apps have updates, so iOS busy downloading and installing it in the background. [...] Additionally, after you install the new iOS version, iOS must do something called "re-indexing." During this process, iOS 11 will comb through all the data on your device so it can catalog for quick Spotlight search. "The article further states that" The good news is that these two things are temporary ".
Within a week of launching update 11.3.1, users began reporting ongoing issues with this update related to battery drainage. Some of these reports show water channels from 57% to 3% in just 3 minutes. Even users with a 96% battery-sized health realize the iPhone is decreasing by about 1% per minute. In addition to the battery channel, some iPhone users are realizing that their device has excessive heat buildup.
It has been recommended by technology experts that users do not upgrade their software until the release of the version after 11.3.1 unless specifically disturbed by 'third-party display issues'.
Fleas Calculator
In October 2017, users reported on Reddit who quickly typed the equations in the default iOS calculator app gave the wrong answer, especially making the "1 2 3" query generate "24" instead of "6". Analysts have blamed the animation lag caused during the redesign of apps on iOS 11. The problem can be done by typing the numbers slowly, or by downloading an alternative calculator app from the App Store that does not have this problem. With a large number of bug reports submitted, Apple employees, Chris Espinosa, indicated on Twitter that the company was aware of the issue. iOS 11.2 fixes the problem.
Auto keyboard configuration bug
In November 2017, users reported a bug on the default iOS keyboard, where pressing "I" resulted in the system displaying text as "!" or "A" along with an unintelligible symbol that displays a question mark in the box. This symbol is known as Variation Selector 16 for purposes intended to combine two characters into emoji. Apple acknowledges this problem in the support document, suggesting users to set the Substitute Text feature in their device's keyboard settings as a temporary solution. The company confirmed to The Wall Street Journal that devices using the older version of iOS 11, compared to only the current 11.1 version at the time of publication, were affected by the issue, and Apple's spokesperson announced that "Improvements will be released soon ". iOS 11.1.1 was released on November 9, 2017, fixing this problem.
At the end of the month, another keyboard autocorrection bug was reported, this time replacing the word "It" with "I.T". MacRumors recommends users to set the Substitute Text feature in the same way as they did for previous autocorrelation issues, although the report notes that "some users insist that this solution does not solve the problem". It was fixed with iOS 11.2 release.
December 2nd strike
In early December, users wrote on Twitter and Reddit that, exactly at 12:15 am local time on December 2, App Store apps that send local notifications will cause the device to repeatedly restart. Reddit users report that disabling notifications or turning off background app refreshes will stop the problem, while Apple staff on Twitter report that it is a bug in handling dates, recommending users to manually set dates before December 2nd. MacRumors writes that the problem "seems to be limited to devices running iOS 11.1.2", with users on beta 11.2 unaffected. iOS 11.2, released on the same day, fix this problem.
iOS 11.2 HomeKit vulnerability
In December 2017, 9to5Mac discovered a security vulnerability in iOS 11.2 in Apple's HomeKit smart home system, allowing unauthorized access to smart keys and garage door openers. He noted that Apple has issued server-side improvements, while preventing unauthorized access, as well as limited HomeKit functionality, with upcoming software improvements for iOS operating systems intended to restore lost functionality. On December 13th, Apple released iOS 11.2.1, which sets restrictions on remote access.
Additional iOS 11.3.1 issues
Issues with update 11.3.1, other than battery disposal issues, include: AirPlay issues, Touch ID issues, abnormal lag numbers, voice issues, missing battery indicators, and issues with first-party and third-party applications. The issue is also centered around iPhone Face ID.
Supported devices
iOS 11 dropped support for devices with 32-bit processors: especially iPhone 5, iPhone 5C, and fourth-generation iPad. This is the first iOS version running exclusively on iOS devices with 64-bit processors.
