This is an application that fixes the screen in a specific orientation regardless of the attribute of screen rotation of the displayed application.
You can change the orientation of the screen from the notification area. Depending on the terminal, some screens are not supported, so not all settings can be used.
Because it forcibly changes the display of the running application, it may become inoperable or the worst crash may occur.
Please use at your own risk.
