Well, as we know there are lots of applications (mostly games) that need tilting (such as Temple Run). But my Galaxy Tab 4 just doesn't. Nor does it rotate. I have checked the auto-rotation option found in the settings, and the screen rotation option in the notification panel. I have tried almost every way to fix this by myself. I kept searching for a solution on the Internet but none have seemed to help . I also downloaded apps that can be used to calibrate but they don't work for me (you have to get the ball into the center, but the ball that appears on my screen is stuck on the upper left corner. And I can't do anything to move it). Please does anyone know how to fix this?
