Default [Q] CM11 Samsung Galaxy S4 Compass issue

I'm running the 2014 - 01 - 05 nightly on my Samsung Galaxy S4 M919. The compass works on some apps but not on others. I thought it was hardware until I found that the gyros work in all axis for games such as F-Sim and compass apps such as Advanced Compass. BUT, in the app GPS Status & toolbox, the compass and pitch and roll are locked to zero, calibration had no effect. Also the app Google maps shows the compass icon locked to North and will not function with rotation.

Is there something in CM11 that changes the way the accelerometers communicate with apps and some of them can interpret the data??

Cheers

It's possible that the app that isn't working isn't compatible with KitKat ROMS yet.

Not all apps have been updated.

Yes, I see this too. In maps the compass works after about 10-15 seconds. As you say, the compass in "GPS Status" seems locked.
I don't see much traffic about this problem and I wonder if it is an S4 only issue (I'm using the tmo version jfltetmo).
Looking at the raw sensors in the "Sensor List" app I see the data all the time (YAS532 Magnetic sensor), so I don't think there is any hardware problem (or even low level software issue).

I too have this problem, but it worked on CM11 with the December 2013 nightlies. It's only recently that this has been a problem for me. I am using the Rogers S4 (jfltecan) and am using the latest unified build for jflte.
