With every new iOS release come several new features that Apple enthusiastically introduces during its annual WWDC event, while a plethora of smaller features go unmentioned. The introduction of iOS 11 followed suit, spotlighting major changes to Control Center and screen shots, new AirPod controls and Screen Recording.
In addition to adding the Loop, Bounce and Long Exposure effects to Live Photos, iOS 11 introduces several new editing features. You can now trim them and change the key photo, which is the photo that displays in your album.
iOS 11 has finally added a way of shutting down and rebooting your iPhone or iPad without having to press the Home or Sleep/Wake buttons, which should be a welcome feature for those with malfunctioning buttons. The reboot button is buried annoyingly deep in the Accessibility features while the new Shut Down button is easily found in Settings. Here's how to do both:
Like the Apple Watch SOS feature introduced with watchOS 3, iOS 11 gives your iPhone a shortcut that automatically calls the local emergency services (like 911) and your emergency contacts when invoked. Hopefully you will never have to use it, but if you ever find yourself in dire straits it could prove to be a lifesaver. Once you have it set up, Emergency SOS allows you to push the sleep/wake button rapidly five times, at which point it makes the call.
iOS 11 adds several features aimed at optimizing storage space on the iPhone and iPad, such as Messages on iCloud and the ability to offload apps.
