This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The Screen.unlockOrientation method removes all the previous screen locks set by the page/app.
Note: This method only works for installed Web apps or for Web pages in full-screen mode.
var unlocked = window.screen.unlockOrientation();
Returns true if the orientation was successfully unlocked or false if the orientation couldn't be unlocked.
var unlockOrientation = screen.unlockOrientation || screen.mozUnlockOrientation || screen.msUnlockOrientation || (screen.orientation && screen.orientation.unlock);
if (unlockOrientation()) {
// orientation was unlocked
} else {
// orientation unlock failed
}
