Default [Q] Gyro sensor not working

Lately I noticed that I cannot change my screen orientation by tilting my nexus, so I downloaded an app for testing the sensor, where it didn't move, every dot was in the center of the circle. I am running CM11 nightly with elementalX Kernel, but it a week ago everything worked fine. Even after a reboot, the dots remain at the center of the circles of the test app.
Is the hardware broken or is it a CM bug? Thanks in advance
