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.
