Hi,
I dunno why this happens. But my phone will just stop rotating (with auto rotate checked on). If I check mail it will stay sideways. Then it will rotate back on home screen. I have pulled the battery, I have recalibrated it. The only thing that works is resetting it. I am really getting annoyed resetting it so often and reinstalling everything then setting up the accounts of everything I reinstall. Anyone have any information as to why this happens and what I can do to fix it that is a little more convenient then resetting it to factory? Example is I restarted everything was north and south. I turn it sideways and it stays sideways.
Addition.
forgot to mention. When I leave current app and go to the next. Say I go from email to Navigation the navigation will be and stay sideways also.
