Looking for solutions, stumbled across this. My compass is reliably 180 degrees out and no amount of calibration, etc. seems to help.
What a joke.
Apple really need to resolve this, as if you're lost and it doesn't calibrate you could really be in trouble. Either remove the compass app entirely or make it do a reliable calibration procedure like it used to in IOS versions from a decade ago.
A compass that TELLS YOU BLATANT LIES is worse than no compass.
