    So noticed this at work when I was ‘aiming’ a radar app in the direction of my house and the ‘compass’ indicator was pointing the wrong way. This happened in iOS 11. I am still seeing this in iOS 12. I have an 8+ and my co-worker has the 6S+. Both are exhibiting this behavior. I have tested with Google Maps, Radar Scope and the Compass app.

    When I turn on Use True North the same issue is there.

    It literally seems to be ‘aiming’ with the right side of the phone. I have done multiple soft-resets.

    Anyone else have this issue?

    It’s our building. Something is jacking up the signal. Sorry y’all. We tested outside and 100% normal.

    FWIW.. and was throwing us off, is that the Pixel 2XL is unaffected. However, today after a few minutes it even prompted to recalibrate.

    On both our IP XS and IP 8, the compass app seems to be in error. The true bearing up our street that is 270 degrees or West, but they both read 255 degrees, whether true or magnetic.

    The local magnetic variation here is 16 degrees positive. The correct solution to finding true heading from magnetic heading is MH - magnetic variation. Thus, if my street points to a true baring of 270, the magnetic heading should be 286 up the street.

    No big deal, but I wouldn't want to be navigating a boat across the Pacific with my iPhone compass.

    While I have no need for the Compass app, it seems that on previous phones, the compass was fairly accurate. Wondering if the problem is iOS 12?

    In the same spot that our iPhones (6S+ and 8+) have the problem, my IPP 10.5 does not have the issue.
