I have a G1 that the accelerometer has stop working on. The Screen will still go into landscape mode when the keyboard is opened ... and the app is set to switch orientation for that. When I close the keyboard the display does NOT return to portait on its own. I have to double tap a Clock/Weather widget to get the orientation back to Portrait. Without that widget i have to reboot the phone to get the display back into portrait... Anyone have this happen to their phone and did you find a solution ...? I am afraid that this is a pure hardware failure ... and not sure if the Accelerometer is a possible/easy item to replace in the phone ... So now all apps that use the accelerometer fail ..
