Getting to know your phone 17
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.
