Android Hidden Trick: How to lock screen without lock button

To lock your phone screen, all you have to do is double-tap anywhere in quick succession on the lock or home screen. You can then use the same gesture to unlock the display again, but you will then have to re-enter your PIN or unlock pattern.

As a rule, the function is preset on smartphones from Samsung and Xiaomi. If this is not the case, you can activate the feature in just a few steps in your settings:

  1. Go to the settings,
  2. Then up Advanced features and there on the rider movements and gestures.
  3. Now activate the option Double tap to turn offby using the slider.
However, double-tapping only works if you are not using any other app, such as WhatsApp or Instagram. With MIUI, the operating system of Xiaomi phones, the gesture can only be used from the lock screen.
