A ‘Back Tap’ button has been added in the latest update of the mobile operating system to perform specific tasks.

Apple has secretly introduced the Back Tap feature, which will allow the users to perform certain tasks by double-tapping the back of their phones.

This button is not physical and can be enabled from the settings option of the iPhone.

One of the popular functions of the iPhone is taking a screenshot by double-tap. While Fox 8 reported that a user can also access other functions, including Control Center, Notification Center, Reachability, Shake, Siri, App Switcher, Home, Lock Screen, Mute, Spotlight, Volume Down, and Volume Up.

Custom shortcuts can be accessed now by double or triple tap which usually works from the home screen and the lick screen.
