Magnetic compass doesn't work at all

  • Magnetic compass in my 945 LTE doesn't work at all. Outside inside. Doesn't matter. I hope it's just a software bug and will be repaired. The compass needle stays in the same position to the watch face. Won't move with me rotating the watch at all. 

I tried to calibrate the compass but this feature also didn't work. It never says calibration finished our anything similar. 

Edit:

After many attempts I managed to calibrate the compass. It works now. 

Edit 2:

Magnetic compass needs to be calibrated often. Almost every day. Calibration is possible ONLY after switching off and on the whole watch.
