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
its LCD and touch screen functionalities. Do not cover the LCD’s
proximity sensor with a protective film. This can cause the sensor to
malfunction.
TIPS
- Tap the Menu Key whenever you open an application to check
what options are available.
- If your phone has errors when you use it or you cannot turn it on,
remove the battery, install it again and turn it on after 5 seconds.
