I have a Le Pan II. And, I noticed this issue shortly after installing MX Player (though I am not certain it is related to that app). Now, when I power on the tablet auto-rotate is disabled (locked in landscape). I enable it and it works fine. Next time I power down & up, it is disabled again. MX Player had a default "landscape rotation" and that is where my Le Pan was "sticking". I upgraded MX Player, switched that apps default to auto-rotate, power cycled the Le Pan and booted to a disabled auto-rotate, as before. I uninstalled MX player with no improved results. I reset the tablet to factory (deleting even SD card data) and it still boots disabled but locks in the booted orientation. I assume one of the start-up Linux files has been messed with by an app (not to mention the suspects name again), but I haven't got permission to look at the start-up files. Anyone have any ideas on how I might correct this?
