Compass off by 90 to 180 degrees

I've noticed that my compass is way off when hiking. I'm not sure when it started, but it's off by 90 to 180 degrees. I've started noticing this because my direction line in Locus is pointing in an opposite direction.

I've calibrated my device in Google maps (Samsung S10) and it says accuracy is high. In Google maps the compass is working accurate. I tried wiping the cache of the phone and wiping the cache of the app to no avail. In Locus the compass is still way off. Ive tried some other GPS settings in the app. The compatability mode kind of works but it behaves erratically (it acts nervously).

I've also tried a competitive app (Osmand) which gives the same problem. This makes me conclude that it's not a Locus problem but a system problem. Do you have any idea how I can fix this? Does Google maps use another compass?

What else can I try? Thanks. Kind regards.

Was your phone maybe near a metal or magnetic object when using Locus and Osmand and not so when using Gmaps? Flip-cases or bike-bars are givng problems for compasses.

@Henk, thanks for you reply. I kind of figured it out. My compass wasn't calibrated. This was very confusing because apparently in Google maps the calibration movement is different than the Samsung calibration movement. I figured this out after a lot of reading on the internet. So, now it works. However, my phone doesn't seem to persist this calibration because when I use Locus I have to recalibrate it every time I get my phone out of my pocket again. Very annoying.

I think this happened after a system update because I never had this problem before and I don't have a new case.
