Turn On/Off Screen-off Gestures auf Oppo
Screen-off gestures let you trigger actions on your Oppo phone while the display stays dark. The feature sits inside the convenience tools of Coloros and covers actions like waking the screen, opening the camera, or turning on the flashlight without unlocking the device first.
If a gesture stops responding, either the master switch for Screen-off gestures is off, or the individual gesture itself got disabled on its own. Both live in the same menu, so check the group toggle before troubleshooting a single gesture.
Where to find the setting
Open Settings ➔ Convenience tools ➔ Gestures & motions ➔ Screen-off gestures. From there you can Enable or disable Screen-off gestures for the whole group, then Turn On/Off the desired Gesture one by one, or tap Add gesture to draw a custom pattern.
Turning the whole feature off cuts down on accidental camera launches from a pocket, which usually drains battery faster than the gesture sensor itself. If you only rely on one gesture, disable the others individually instead of switching off the entire feature.
