Answer to: G-sensor, accelerometer doesn't work?Take apart the motherboard and see if it's warped / bent near the wifi antenna connector. There is a small slot on the frame and the board has to go in there. If you overlook this and screw everything back in place, the forces will warp the board. Happened to me, learned it the hard way :( The acc/gyro chip (330DC) is in that area. If the board is warped, it may break the solder joints of the chip. You can straighten the board again with pliers, but that didn't fix the solder joints in my case, good luck.
