Thumbs down [Q] G-Sensor not calibrated

Hello, i'm using stock Atrix 4G, i've tried to play the NFS:SHIFT that is included on the Stock 2.3.6 Retail Rom and it feels while in landscape que accelerometer is misplaced a few degrees to the right, so i have to tilt the Atrix to the left if y need to center it.

I'm trying to calibrate it but compass config didn't helped, anyone knows a fix??

Thanks!

(PS. The same happens on every game)
