Something went horribly wrong with auto rotation. When i activate my auto rotation the screen goes upside-down and stay that way and doesn't rotate like it supposed to.. Any suggestions how to fix this?

Me neither. In fact, auto-rotate works so seamlessly for me that I often find myself holding the Tab upside-down, i.e., with the power button near the lower right-hand corner.Never heard of that or experienced the problem

Never heard of that or experienced the problem (and we have two GTab 10.1's in this household). Does it still do it after a reboot, or if you toggle Auto-rotation off/on from the notification area? Are you running any third-party apps that might also have an auto-rotation feature? For example, many launchers have a toggle for this, and it might be at odds with the setting in the tablet.
