Set phone to vibrate for calls

You can set your phone to vibrate while ringing when you get a Duo video-call notification. As long as you don't have the phone's sound muted, the phone will ring and vibrate.

Note: This setting is only available for Android phones.

1. Open Duo.
2. At the top-right corner, tap More   Settings. 
3. Turn on Vibrate while ringing.
