Hi everyone. Compass is stuck in my s4 mini. From sensor test (*#0*# then sensors) I can see this (see attachment). It seems like magnetometer is not calibrated. Any way to calibrate it (apart from usual methods like 8 figure or rotate phone around tre axis since I already tried them and they didnt worked) or reset it to stock values? Tried factory reset too.

thanks a lot guys.. I really need help, It may be an hardware issue but I want to try everything via software before send it to sammy

I have the same problem. I have tried to rotate phone along his three axis, while in sensor screen. Phone vibrate and light green during this operation and "need calibration " disappeared... Now only number "3" is displayed.

Unfortunately, I tried calibration in sensor screen too but nothing happens. Always "need for calibration 0".

Found out that the problem was the kernel. As soon as I flash a kernel different from the stock one, compass get stuck. On stock rom and JB at least... be careful.
