bad theory
I could not trigger the bug by letting the screen time out while in landscape mode. Tried several apps and screens, tried resuming right away, resuming afer 20 minutes and screen autorotated evrey time. Was working good for 3 days and then all of a sudden frozen in portrait mode.
I do notice that the compass and level functions on the swiss army knife app is jumping around like crazy while the bug is triggered. Reboot resets all back to normal untill the next instance.
ok so I think i may have figured out a way to fix (or prevent) this bug from occurring; wanted to share. while i still haven't found the absolute cause of the problem i have found that if i let the screen time out while it's rotated horizontally it will stay like that until returning to the home screen, or any app that requires the vertical orientation. this then causes the auto-rotate to not work until rebooting the phone (POWER + VOL DOWN button). if you let the screen time out while it's vertical this doesn't seem to happen, and the auto-rotate will work fine. just a theory but so far so good, i've been trying to make sure to return to the home screen, or anything else using the regular orientation, before letting the screen time out.
