On my past iPhones, the compass always got screwed up over time somehow. Sometimes recalibrating fixed it, but only for a minute.

Yep - exactly what I’ve experienced. Calibrate the compass and at least it’s within a right angle of being correct. But the problem returns.

		Was it serviced? In some models they used to have a non-ferrous screw put next to the compass, if a tech puts the wrong one in it will not calibrate.
