==== Touch ID ====

In iOS 7.1, [[Touch ID]] was not functioning on the [[iPhone 5S]]. The problem cannot be resolved by turning Touch ID on and off in the "Fingerprint and Passcode" menu, restarting, resetting, or restoring the device using [[iTunes]].<ref>{{Cite web|last=Prabhu|first=Gautam|date=2014-03-12|title=iPhone 5s users reporting issues with Touch ID after iOS 7.1 update|url=https://www.iphonehacks.com/2014/03/iphone-5s-touch-id-issue-ios-7-1.html|url-status=live|archive-url=|archive-date=|access-date=2021-01-30|website=iPhone Hacks|language=en-US}}</ref> This issue was fixed in iOS 7.1.1.<ref>{{Cite web|last=Kingsley-Hughes|first=Adrian|title=Apple releases iOS 7.1.1|url=https://www.zdnet.com/article/apple-releases-ios-7-1-1/|access-date=2021-01-30|website=ZDNet|language=en}}</ref>

==== iMessage ====

When a specific sequence of Arabic, Unicode, and English characters are sent through iMessage to an iOS device running iOS 8.0 or later, it causes the device to crash.

Apple has since released a software update (iOS 8.4) to fix this issue.<ref>{{cite web|url=http://www.theinquirer.net/inquirer/news/2410183/ios-bug-lets-android-and-windows-phone-users-disable-your-iphones-messages-app |archive-url=https://web.archive.org/web/20150529002053/http://www.theinquirer.net/inquirer/news/2410183/ios-bug-lets-android-and-windows-phone-users-disable-your-iphones-messages-app |url-status=unfit |archive-date=May 29, 2015 |title=iOS 8.4 includes fix for iMessage bug plaguing iPhone users|work=theinquirer.net}}</ref>
