listening tips
When you're on the move, you can listen to your music
through a wired headset connected to the phone's
micro USB connector or by using a wireless headset.
When you're on an airplane or somewhere that calls are
prohibited, you can turn off your network and
Bluetooth™ connections and still use a wired headset to
listen to your music. With the slider closed, from the
7
home screen, press > Settings > Phone > Airplane Mode
> On.
