A:Answer I thought the same. It seems as if the rotation sensor gets "stuck" and needs a little tap or shake to make it work when you physically rotate the screen. I leave the screen rotation lock/unlock setting off. Try using the program Asus ScreenXpert (in MyAsus) which has a screen lock/unlock button. TIP, if your camera screen turns green it's caused by using any of the camera setting in the MyAsus program, select NONE. Recommend installing Bluestacks 5 if you want to use Android Apps from Google Play store. Good Luck!
