Hey, my Nexus 5's sensors stopped working suddenly. Nearly all of them: Gyroscope, accelerometer, magnetic rotation, magnetic orientation, step counter. The only remaining sensor is the light and proximity sensor.

I don't believe in a hardware issue tbh, because according to iFixit, the magnetic sensor is a separate part from the other sensor cluster, and it suddenly stopped working without dropping the device.

Here is what I tried already:

*Flash KitKat

*Clean flash 5.1.1 again

*Flash M preview 3

*deleting /persist/sensors/sensors.reg file

*fsck the /persist partition

*taking the device apart, checking every connection and put it back together

*whacking the device against my palm repeatedly and quite firmly

Is there anything else I should try?
