Choose one of the following options: Answer call, go to 1a. Reject call, go to 1b. Silence the incoming call alert, go to 1c.
Tap the accept call icon and drag the icon right.
Tap the reject call icon and drag the icon left.
When you reject a call, the caller will hear a busy signal or be diverted to your voicemail.
Tap the upper or lower part of the Volume key when you get a call. The incoming call alert is silenced. If you take no further action after silencing the incoming call alert, the call continues until the caller disconnects or the call is diverted to your voicemail.
You can silence the incoming call alert if you don't want to answer or reject the call right away. Afterwards, you can still answer or reject the call.
