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.
