iOS 8 Beta 1 was introduced at the company's Worldwide Developers Conference on June 2, 2014, and it was released to developers later that day. From then until September, new beta versions were seeded to developers typically every two weeks. Each new beta version contained bug fixes and improvements over the previous version.
On September 9, 2014, at their 'Wish We Could Say More' event, Apple introduced the iPhone 6 and 6 Plus, a new mobile payment service called Apple Pay, and the Apple Watch. At their event, Apple also announced that iOS 8 would see a public release on September 17. The Golden Master version was seeded to developers shortly after.
iOS 8.0.1 was released on September 24, 2014, but this update was withdrawn due to an issue that disabled Touch ID and cellular network connectivity on iPhone 6 and iPhone 6 Plus. Later on the next day, Apple released iOS 8.0.2.
On October 16, 2014 at their "Its Been Way Too Long" event, Apple introduced the iPad Air 2, iPad mini 3, new Mac mini and the iMac with Retina 5K display. At the event, Apple also announced that iOS 8.1 would see a release of October 20. iOS 8.1 saw the return of the camera roll album, the introduction of Apple Pay, a redesign of the iBooks icon and Reader view icon in Safari, an option to Enable/Disable dictation in keyboard settings, and bug fixes.
iOS 8.1.2 was released on December 9, 2014, addresses an issue where ringtones purchased through the iTunes store may have been removed from the device.
iOS 8.1.3 was released on January 27, 2015. This update includes general performance and stability improvements, and it also reduced the amount of free space necessary to update a device over-the-air. It requires around 600 MB for iOS 8 users and 3 GB for iOS 7 users to update over-the-air.
iOS 8.2 was released on March 9, 2015 at their "Spring Forward" event, which includes support for the Apple Watch, along with improvements to the Health app, stability enhancements, and many bug fixes. It was released to the public within a few hours.
iOS 8.3 beta 3 was seeded to developers on March 12, 2015. A new iOS public beta program was also announced, allowing members of the public to download and test the iOS 8.3 beta. iOS 8.3 was released on April 8, 2015, with its update focuses more on bug fixes and improvements, such as performance issues, improvements on Wi-Fi and Bluetooth, improvements on Messages, improvements on CarPlay, a new Emoji keyboard with over 300 characters, and other bug fixes.
iOS 8.4 was released on June 30, 2015; the update comes preloaded with the new Music app that contains both Apple Music and Beats 1, Apple's worldwide radio station, with some improvements on iBooks and bug fixes.
iOS 8.4.1 was released on August 13, 2015; the update resolves issues that could prevent turning on iCloud Music Library, along with other bug fixes.
iOS 8.4.1 is the last version of iOS 8.
Photos and Camera
The Photos app contains more tools for editing photos. The cropping feature now enables rotating images both clockwise and counter-clockwise. Furthermore, users can set the desired brightness and colors for photos. In iOS 8.0, the Camera Roll and My Photo Stream albums were removed; they were brought back in iOS 8.1. The Camera app now features a shot timer for the front camera, which can be set to 3 or 10 seconds. The camera also has a new time-lapse mode.
Notification Center has been redesigned, only having two tabs (Today and Notifications), whereas the Notification Center in iOS 7 had three tabs (Today, All, and Missed). Users can now add or remove custom widgets from third-party applications in Notification Center with the "Edit" button located at the bottom. This also allows the rearrangement of notification widgets. The "Clear" button that is used to clear notifications, has been tweaked to make it slightly more visible. Users are also now able to reply to certain notifications (messages, calendar alerts etc.) directly by swiping down at the notification when it appears.
In the Messages app, users can send audio and video messages by holding down the record button. In group conversations, users can add or remove someone from a thread, name a thread, share their location in a thread, view all attachments, and turn on Do Not Disturb to not receive notifications from a specific thread. There is also an option for messages to be automatically deleted after a month or a year.
iOS 8 includes a new predictive typing feature called QuickType, which displays word selections above the keyboard as one types. The feature can be turned off in Settings, or hidden using a swipe gesture. Additionally, iOS 8 allows users to install third-party keyboards. Many developers have ported their keyboards to iOS, including Minuum, Perkee, Swype, SwiftKey, Fleksy and Adaptxt.
In Family Sharing, a user can add five others as family members. Family members can share purchased apps, music, movies, TV shows, and books using the same credit card. Family members can also sync photo streams, calendars and their location history with each other. One can send iTunes download requests to another accounts for approval if the user is signed up as a child.
iCloud Drive is Apple's file hosting service for devices running iOS 8 or OS X Yosemite. Users can save photos, videos, documents (Keynote, Pages, and Numbers), and music, and application data to iCloud.
HealthKit is a service that allows developers to make software that integrates with the new Health application. This application allows users to track their steps, oxygen, sleep levels, and other health related data. Additionally, users can enter their medical history in Medical ID, which is accessible in the lock screen, in case of an emergency. The Healthkit application, called 'Health', is available on an iPhone 4S or later and iPod touch (5th generation) or later.
HomeKit is a database similar to HealthKit and PassKit that allows developers to make software that discovers, configures, communicates with and controls devices for home automation. Actions can be grouped together and can be initiated using Siri either from home or Apple TV.
There are also the option for manufacturers of existing equipment to make gateways that connect equipment using their protocols to HomeKit, which includes equipment manufactured by Insteon As the products talking to HomeKit directly need to be certified with Apple's MFi Program and currently require an encryption co-processor, it is likely new devices will be needed to open HomeKit.
iOS 8 and OS X Yosemite support Continuity, which allows all text messages to be read and replied, and make and receive voice and video calls on their Mac and iPad.
Continuity includes Handoff, which allows users to share documents, e-mails, and websites over Wi-Fi or personal hotspot between iOS 8 and OS X Yosemite devices. Handoff also allows users to start their work on one device and continue on another device.
This feature is supported only on compatible Macs with Bluetooth LE running OS X Yosemite, and on compatible devices running iOS 8. The following devices (iPhone 5 or later, iPad (4th generation) or later, all iPad Mini models, and iPod touch (5th generation)) running iOS 8 will be supported.
In iOS 8, Spotlight is integrated with a number of web services so that users can search using Wikipedia, Bing, or Google. Spotlight can also search for news, nearby places, suggested websites, movie showtimes, and content that is not already on the device from the iTunes Store. Spotlight is also available in Safari, which searches for services (e.g. Wikipedia) linked to Spotlight.
The multitasking screen now shows a list of recently called and favorited contacts, which can be turned off in Settings.
Siri now outputs what users say as they speak for more accuracy and has integrated Shazam support. Holding down the home button will activate Siri, and speaking "What's playing?" will identify what song currently is playing. Speaking "Hey, Siri" whenever the device is plugged into a power source will activate Siri if the feature is turned on. Purchasing content through Siri is now possible, and Siri now has support for 22 new languages.
Wi-Fi calling has been added to allow mobile phone calls over Wi-Fi. AT&T and Verizon and Vodafone have plans to launch Wi-Fi calling for its customers in 2015. Wi-Fi calling is available to T-Mobile and Sprint customers in the United States, EE customers in United Kingdom, as well as Three and SmarTone customers in Hong Kong.
On September 24, 2014, the iOS 8.0.1 release crippled iPhone 6 and iPhone 6 Plus of Touch ID and cellular. The update was released at 9:00 AM PST, and approximately at 11:00 AM PST, Apple removed the update due to these problems, as well as other minor issues. A day later, Apple released iOS 8.0.2 which contains all the fixes included with iOS 8.0.1 and also fixes the problems that iOS 8.0.1 introduced.
There are currently some unfixed Bluetooth, Wi-Fi, and battery issues. There is still no official statement from Apple about the issues that will be fixed in the future.
On March 9, 2015, the date iOS 8.2 released, many users, mainly from East Asia, reported missing characters in games after upgrading to 8.2. Many game developers were confused about the possible cause, as the problem was arbitrary. The problem was later found to be related to the change of font location, and Unity, a game engine powering such games, fixed the bug.
On April 8, 2015, Apple Inc. released iOS 8.3 and on the next day, many iPhone and iPad Air 2/iPad Mini 3 users reported on Apple Support Communities and Reddit that after upgrading to iOS 8.3, they have completely lost the ability to use Touch ID in the App Store. Instead of a prompt to verify their fingerprint before purchasing or downloading any new app, the App Store asked affected users to enter the password of their Apple ID. Disabling and re-enabling Touch ID for App Store has not solved the issue for the affected users, and at the moment, there is no solution to this problem.
On May 27, 2015, a serious bug, known as the "effective. Power" bug, was widely publicized which causes a crash upon receiving a specific text message. This flaw has been exploited for the purpose of trolling, by intentionally causing others' phones to crash. The bug was fixed in iOS 8.4.
iOS 8 received mixed reviews. Brad Molen of Engadget said, "To be fair, much of the focus on iOS 7 was on getting developers up to speed on the design overhaul; iOS 8, on the other hand, is all about adding functionality to the iPhone and iPad. As a result, you’re not going to see many significant changes to the layout or design of iOS this time around. In fact, you may not even be able to tell the difference between iOS 7 and 8 unless you’re looking closely. But don’t let looks deceive you: There’s a lot of new stuff under the hood." Charles Arthur of The Guardian said, "There’s no radical change in appearance; instead, there are deeper changes, and an overall cleaning up of the interface."
Darrell Etherington of TechCrunch said, "Best for me has been the ability to mute and leave group conversations, which is something I’ve been sorely missing since the introduction of group iMessage conversations. My family can tend to get pretty chatty on these threads, and while that’s generally fun, it can also be a huge distraction during work events, and during other times when I’d appreciate not getting a whole lot of noise mixed in with my signal. Martin Byrant of The Next Web said, "These features won’t set the world alight for everyone, but they work well and they’re nice extras for people who send a lot of iMessages. That’s especially true if you own a Mac as of course messages are synced there too."
In September 2014, a hoax Apple advertisement for an alleged feature called "Wave" of iOS 8 circulated on Twitter, promised users that they would be able to recharge their iPhone by heating it in a microwave oven. This feature does not exist, and the media cited numerous people reporting on Twitter that they had destroyed their iPhone by following the procedure described in the advertisement.
Since its release, many people had complained about the amount of storage iOS required to install iOS 8. It requires around 5.5 to 6.5 GB of storage for the installation process to complete over-the-air. Once installed, it takes up on average 740 MB more storage on iPhones and iPod touch and 1-2 GB on iPads than iOS 7. iOS 8.1.3 fixes this issue.
Version history: iOS devices
Apple announced iOS 8 on June 2, 2014 at its annual Apple Worldwide Developers Conference (WWDC) event, with its release announced for September 17, 2014. With this release, Apple continues the cycle to drop support for older devices. However, unlike past releases, which usually dropped support for 2 devices, iOS 8 only dropped support for one device, which was the iPhone 4. Supported devices are the iPhone 4S onwards, iPod Touch (5th generation) and all iPad models apart from the first generation (the iPad 2 onwards, and the iPad Mini (1st generation) onwards). The iPad 2 is also the first iOS device to support six major versions of iOS (iOS 4, iOS 5, iOS 6, iOS 7, iOS 8, and iOS 9), despite having less powerful hardware than its successors.
