Have the same issue. 3 hours ago i had no problems with the accelerometer at all. everything was working fine.
then all of a sudden i notice that its not working. only change i did was upgrading from RA recovery 1.2.1H to 1.2.3H. after that, all was still ok. then now its not working all of a sudden.
tried that. still not working.
Compass app is not pointing north,
abduction is no responding to tilts.
followed the instruction to the letter. and still nothing.
could this be a hardware issue?
