GPS TRACK is the direction you are moving and needs movement above about 5 m/s (10 kt) with a good GPS fix. For a stationary device choose Magnetic or True heading. True heading needs Location access.

CHECK COMPASS / UNCALIBRATED

Move the phone away from metal, magnets and magnetic cases, then move it in a figure-eight to recalibrate the compass. The accuracy value is shown in the diagnostics strip (Pro).
