Your Android device has an accelerometer that detects its orientation by measuring angular velocity and helps rotate your screen.

If your Android's auto-rotate functionality is on, but the phone screen doesn't auto-rotate, it could indicate a minor glitch or hardware issue. In this case, your first step is to restart your phone.

If your Windows screen has suddenly turned upside down, it's likely due to an accidental key press or a display setting issue. Here are the steps to quickly and easily fix this problem.

The ultimate in multitasking is being able to view your phone's display on your PC monitor, saving you the trouble of having to volley between two screens.
