That does not work for me at all. None of the auto-rotate apps make any difference on my tab.

tWell this method works like a charm for me but only on thors roms- requires 2 reboots and everything works great. I m on unlocked bl and thors rom v170.

What you can try is powering down ur tablet and powering it on after a period of like 5 mins allowing for residual voltages of the sensors to drain. Or try the hard reset pinhole.

Different methods work for different peeps. I can just hope acer releases an update fixing all of these issues.

Lets hope for the best xD.
