Install If You Want to Record Your Screen
The iOS 11 update comes with a nifty feature that allows you to record your screen.
Apple calls the new feature (surprise!) Screen Recording which allows you to take a videos of your screen. This could come in handy if you're trying to show a friend how to access something or if you're trying to help a family member troubleshoot an iOS problem.
The feature is extremely easy to use and you can add it to Control Center (via Control Center's settings) for easy access.
Simply tap the icon and then tap it again when finished to save a video to your Camera Roll.
