Turn on/off Auto-rotate screen quickly by long pressing search button.
When you are lying on bed. The screen changes to landscape. Have to open system settings to disable Auto-rotate screen. Did you find it is really inconvenient? This app provides a super easy way for switching this setting.
And it provides a state icon to indicate the current setting.
