Silence or ignore incoming call
Ever wondered how to silence or ignore an incoming call when your phone is locked? When you are already using the phone and an incoming call appears, you are presented with a green or red button to answer or ignore the call, respectively, but you only get the green "answer" button when the phone is locked. This is where the ringer switch comes in:
- To silence the ringer, simply press the phone's power button once. Per the comments, you can also tap either volume button.
- To ignore the call altogether and send it to voicemail, press the phone's power button a second time
