How to use your iPhone’s Back Tap feature

Back Tap is one of the easiest ways to put an iPhone function you use all the time literally at your fingertips. It is exactly what it sounds like: a way to access different phone features by tapping the back of your phone - kind of like an extra, user-customizable button. It was introduced with iOS 14, and the feature works on devices as old as the iPhone 8, which was launched five years ago - so it's highly likely that you've got a compatible phone.
Here's how to set up Back Tap. For reference, I followed these steps on an iPhone 13 Pro Max running iOS 15.4.1.
- Go to Settings > Accessibility > Touch > Back Tap
- Choose Double Tap or Triple Tap to set a custom function for those gestures
