Getting to know your phone
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.

WARNING
Placing a heavy object on the phone
or sitting on it can damage the LCD
and touch screen functions. Do not
cover the LCD proximity sensor with
protective film. This could cause the
sensor to malfunction.
