Turn On or Off Double Tap to Lock auf Realme
Double tap to lock is a gesture built into Realme UI that lets you lock the screen from the home screen without touching the power button. It works on any empty area of the home screen, not inside apps or the app drawer.
This is useful if your power button is hard to reach, worn out, or you simply prefer gesture-based control. Once the screen locks, any password, PIN, pattern or biometric lock you configured separately still activates as usual, so the gesture only replaces the button press, not your security setup.
Where to find the setting
Go to Tap on Settings ➔ Tap on Home screen & Lock screen ➔ Enable or disable Double tap to lock. Toggle it on to activate the gesture, or off if double taps are locking your phone by accident while you use widgets or rearrange icons.
If the toggle has no visible effect, make sure you are tapping a truly empty spot on the home screen and not a widget, folder or app icon, since those intercept the tap before it reaches the lock gesture.
