This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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();

Return value

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
