Hi 
I’m using Google’s Sky Map on my Fairphone 4 which runs on /e/OS 1.20.
When starting the app, it reports that the compass is not properly calibrated:
I tried to calibrate it as shown in the linked video. However, the accuracy never reaches a high value and therefore this warning is always displayed on startup.
Is there anything I can do?
Regards and thx
Have you tried this out in the open (trying to avoid nearby sources of magnetic interference)?
Do you use a protective case including metal or even magnets?
Yes, I tried it several times on the beach. I’m just using Fairphone’s regular plastic bumper, so metal shouldn’t be an issue.
I just checked on my Fairphone 3, and I have no problem to get Sky Map’s accuracy reading to “high” with some calibration moves … so at least it’s not an issue of the App.
And the calibration itself, did you do this in the dialog that my screenshot shows or somewhere else?
I did this in the prompt, but it shouldn’t really have to matter. I can do the calibration moves whenever I feel the compass needs improvement, and after just doing some moves it’s improved, without any prompt, mode, menu etc.
Okay, strange 
are you aware of any app for checking the compass calibration? I’d like to remove Google from the equation…
