(get idea here)

1. go to phone pad and dail *#*#6484#*#*
2. tap no. 8
3. cover the sensor first. then tap the "开始校准" the button in the middle
4. move your fingers away from the sensor till the number shows 5.0000000 (or any random number)
5. tap "通过" the button on lower left of the screen to pass
6. you will lead to the next test, which is the physical button test. press all the buttons. and tap the 'back' and 'menu' button. and press "通过" lower left button
7. now tap 'back' to exit you will be asked if you want to exit the test, tap 'ok'
