[Q] Compass not working (Motorola RAZR HD) topic

Motorola RAZR HD (XT925)
CM 11-20140104-SNAPSHOT-M2-xt925
SELinux Permissive

GPS is working fine. But compass isn't working at all. Three or four compass apps that I tried (and which I have successfully used in older phones) either crash or show a frozen needle pointing up as North. Tried for weeks to see compass working and nothing.

Researched and found no plausible solution.

To make things weirder, yesterday, only once, compass worked perfectly in SatStat app. I did nothing different and am now unable to reproduce it. Yes, trying it outdoors, but although one should be able to get compass from GPS, AFAIK it should be available directly from the phone sensors with no need for GPS. Then again, except for yesterday's fluke, it's working neither way.

Code:

adb logcat

for Nice compass shows this:

What would you do to try to fix that?

Thank you!
