The Apple Logo On the Back of Your iPhone is a Secret Button
As part of its most recent iOS operating system update (iOS 14), Apple quietly added a new customizable Back Tap button to your iPhone. You can use this new feature/button to simply program your phone to perform specific tasks on your phone. Here’s how you can set it up:
Go to Settings on your iPhone and go to Accessibility > Touch and scroll down until you see Back Tap.
After you turn on the Back Tap button, you will select double-tap and then choose the function you want to perform when you double-tap the back of your phone.
You can also choose a function for when you triple-tap your phone.
A lot of people use the double-tap feature to take a screenshot – it’s pretty handy.
You can also use the double-tap to launch App Switcher, Control Center, Home, Lock Screen, Mute, Notification Center, Reachability, Shake, Siri, Spotlight, Volume Down, and Volume Up.
iOS 14 is compatible with these devices: iPhone 11, iPhone 11 Pro iPhone 11 Pro Max, iPhone XS, iPhone XS Max, iPhone XR, iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation), iPhone SE (2nd generation), and iPod touch (7th generation).
Happy tapping!
