My p3p had 1.6 and then i upgraded to 1.8 and 1.9 . Soon after i updated to 1.8 i noticed its switching in between p mode and atti mode and after upgrading to 1.9 i still saw the same problem. Today i went to fly it after making sure the error message is gone away and i did a compass calibration before my flight. There were no magnetic interference or powerlines around. And suddenly i noticed the drone is not stable and compass error. On the status i see everything normal but in camera view i see the compass error. Can you please help ???
