Set Incoming Call Volume on the Droid Bionic
Whether the phone rings, vibrates, or plays a ringtone depends on how you’ve configured the Droid Bionic to signal you for an incoming call. Abide by these steps to set the various options for your phone:
On the Home screen, touch the Launcher button to view all apps on the phone.
Choose the Settings icon to open the phone’s Settings screen.
Set the phone’s ringer volume by touching Volume.
Manipulate the Ringtone slider left or right to specify how loud the phone rings for an incoming call.
After you release the slider, you hear an example of how loudly the phone rings.
Touch OK to set the ringer volume.
If you’d rather just mute the phone, touch the Silent Mode option on the main Sound Settings screen.
To activate vibration when the phone rings, touch Vibrate.
Choose a vibration option from the Vibrate menu.
For example, choose Always to always vibrate the phone or Only in Silent Mode so that the phone vibrates only after you mute the volume.
Touch the Home button when you’re done.
When the next call comes in, the phone alerts you using the volume setting or vibration options you’ve just set.
Turning on vibration puts an extra drain on the battery.
