If your phone rings when you don't want to be disturbed, you can silence the ringtone for that call.
If you want to be able to silence your phone by turning it face down, the Flip to silence feature must be switched on. On the start screen, swipe down from the top of the screen, tap ALL SETTINGS > audio, swipe left, if needed, and switch Flip to silence to On.
- When someone calls you, press the volume key or the lock key. You can also turn your phone face down.
