Getting to know your phone
Device components
NOTE: Proximity sensor
When receiving and making calls, the
proximity sensor automatically turns
the backlight off and locks the touch
screen by sensing when the phone is
near your ear. This extends battery life
and prevents you from unintentionally
activating the touch screen during calls.
