Basic information about G3
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.
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.
