Lenovo a2 109a tablet cannot be displayed horizontally after installing desktop software.

I'm sorry for the inconvenience.

Automatic rotation operation of the equipment: first, turn on the gravity sensing hardware switch on the left side of the machine body (if it is turned off, the gravity sensing function cannot be used), then click the menu key-Settings-Display in the display options on the right side of the screen, and check "Auto-Rotate Screen" to turn pages horizontally or vertically.

If this is not possible, please uninstall the third-party desktop and switch back to your own desktop for observation and use. If the above operations still cannot be improved, please try to restore the factory settings of the backup data. If the problem still exists after recovery, it is recommended that you go to the local maintenance site for testing and handling.
