I have M2 Global with flyme 4.5.4I installed on it.
Since day one I had issues with compass sensor, which does not read the compass correction.
I also get errors when trying to run calibration from the developer options.
Tried it on another M2 in the store where I bought it - same issue there, so I believe it's a general issue with M2.

Is this issue resolved in flyme OS 5?
