    3.13 Gyro/Accel Sensor Troubleshooting
    When the Gyro/Accel sensor does not work, the reason is chip problem. If the Gyro sensor IC is damaged, it will do not 
    work even thought power is supplied and MSM8974 controls normally. Therefore if the Gyro sensor is damaged, change 
    the Gyro/Accel sensor IC or main board.

    3.14 Compass sensor troubleshooting
    When the Compass sensor does not work, the reason is chip problem. If the Compass sensor IC is damaged, it will do not

    directly. Therefore if the Compass sensor does not work, change the Compass sensor IC, and Gyro/Accel sensor or main 
    board sequentially.
