Auto-rotate On/Off

Note::

On some devices, auto-rotate is called "Orientation Lock" and may have an icon to switch it on or off after expanding the notification bar. This app will not change the state of the "Orientation Lock" icon. If auto-rotate is turned ON by this app, you can use your device's "Orientation Lock" as usual to control it on or off. If auto-rotate is turned OFF by this app, no matter you set your device's "Orientation Lock", auto-rotate is off.

See section "More by ACTIVE SOFT" for other useful apps.
