Smart Rotate is a completely free app that will give you full control of your screen. You can easily rotate and lock your screen orientation via the buttons on notification panel or the widget. You can also set up smart rotation events.

Modes of rotation:

•Locked Mode
In this mode you can lock your screen to any orientation regardless of the current running app. It is great but it may cause some apps not to display properly.

•Unlocked Mode
In this mode your screen orientation will be restricted by the current running app. The app can rotate the screen only if the running app allows it otherwise it stays as it is.
