Now the iPhone compass automatically calibrates, but there are a few other things you may need to check if the compass isn't working. We'll walk you through the four steps to take to calibrate your iPhone compass.

That's how to calibrate the compass on your iPhone. 

Make Sure True North Is Turned Off

The next thing to check if the compass on your iPhone isn't working is the True North setting. Disabling True North makes your iPhone compass use Magnetic North instead and may clear up whatever is throwing your compass reading off. To do this:

  1. Open the Settings app, and tap Apps.

  2. Find the Compass app by either scrolling through the list or using the search bar.

  3. Toggle Use True North to the left, so it turns from green to gray.

You might be wondering what the difference between true north and magnetic north is. Well, true north is simply the North Pole. It's a fixed point on the Earth. Magnetic north is where your compass points based on the Earth's magnetic field. Disabling True North and using magnetic north should help to calibrate the compass on your iPhone.

Turn Locations Services Off & On Again

Another possible reason your Compass app isn't working is related to GPS errors. The best way to correct this is to turn Location Services off, then switch it on again to reset it. 

Restart Your iPhone

If you've tried all the above steps and your compass readings are still wonky, it's time to restart your iPhone. This step often gets rid of unresponsiveness and glitches and may be the thing you need to reset your iPhone's compass. If this last step doesn't work, it will be time to contact Apple Repair, because you may have a hardware issue.
