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 display and touch
screen functions. Do not cover the proximity sensor with screen protectors or any other
type of protective film. This could cause the sensor to malfunction.
