Problem with direction

Is anyone else having problems with GPS heading? As far as I understand red line is supposed to be the gps heading, but for me it usually points 20-25 degrees to the right from where I'm actually heading. The regular blue arrow points correct.
Also how exactly manual heading mode works?

Thank you :)

Could you post some screenshots? Also what model phone and Android version do you have? I'll get the Android dev to look into it.

The manual mode is a bit tricky at the moment. You need to rotate the map, and that sets the manual heading. In a future version i'm going to have him change it to simply entering a heading manually.

Hmm weird, thanks for the screenshot. I'll get him to look into it.

Also might need to know what country are you in?

If you're still around, can you let me know what model phones you tried on?

This is possibly due to the phone being too slow, and the data collection lagging behind a bit. Mapbox must have low priority when updating it's internal GPS heading. I think it can be fixed.
