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
work even thought power is supplied and MSM8974 controls normally. Also, Compass is connected to Gyro/Accel sensor
directly. Therefore if the Compass sensor does not work, change the Compass sensor IC, and Gyro/Accel sensor or main
board sequentially.
