Hi, I own my new nexus 7 since a few days. It is a really nice device and everything seemed OK on mine until i tried to use the electronic compass. I tried a few compass apps, sky map, google map with compass... Compass doesn't work. It shows a wrong north or stays stuck. I tried Android sensor tools app and the magnometer keeps showing a very high level of magnetic field. Calibration doesn't work. Does anyone has a working compass on its nexus? I'm not sure if i should try to change my nexus as i feel lucky that it is the only issue. I would appreciate your feedback. Thank you.
