Turn Double-tap to Wake Screen On or Off auf Realme
Double-tap to wake lets you activate the screen of your Realme phone without pressing the power button. Two quick taps on the black display turn it on so you can check the time or read a notification.
This gesture is controlled by a single toggle inside the display settings. It works independently from Always On Display and does not affect the power button or fingerprint sensor.
If the gesture stops responding, check whether it was switched off accidentally, for example after a system update or a factory reset. If the screen wakes on its own inside a pocket or bag, turning the gesture off stops accidental touches and reduces unnecessary battery drain.
To enable or disable it, go to Tap on Settings ➔ Tap on Home screen & Lock screen ➔ Enable or disable Double-tap to wake screen.
If double-tap still does not wake the screen after enabling it, a case covering the top of the display or a screen protector with reduced touch sensitivity can also be the cause. In that case, the setting itself is correct and the problem sits with the hardware layer instead.
