Turn On or Off Flip to Mute Incoming Calls auf Oppo
The Flip to mute incoming calls gesture belongs to the gesture controls of Coloros. When it is active, placing your Oppo phone screen-down while it rings stops the ringtone immediately, without touching a volume button or unlocking the display.
This behavior works independently from the general ringtone volume and from Do Not Disturb. If the gesture is off, flipping the phone has no effect on an incoming call, and the ringtone keeps playing until you answer, decline, or the call times out.
Where to find the setting
Open Settings ➔ Convenience tools ➔ Gestures & motions and look for Flip to mute incoming calls. Tap the toggle to switch it on or off.
Turn it on if you often place your phone face-down on a desk or table during calls and want a quick, silent way to cut the ringtone. Turn it off if the phone accidentally mutes calls while lying flat in a bag, a case, or on a soft surface.
Keep in mind this gesture only mutes the ringtone. It does not decline the call or send it to voicemail, and the caller keeps hearing normal ringing tones until the call is answered, declined, or the timeout is reached.
