Control volume
Change the volume
If you have trouble hearing your phone ringing in noisy environments, or calls are too loud, you can change the volume to your liking by using the volume keys on the side of your phone.
Do not connect to products that create an output signal, as this may damage the device. Do not connect any voltage source to the audio connector. If you connect an external device or headset, other than those approved for use with this device, to the audio connector, pay special attention to volume levels.
Change the volume for media and apps
Press a volume key on the side of your phone to see the volume status bar, tap tune, and drag the slider on the volume bar for media and apps left or right.
Set the phone to silent
To set the phone to silent, press the volume down key, tap notifications_none to set your phone to vibrate only and tap vibration to set it to silent.
