On iOS devices, the rotation lock can be found by double-tapping on the Home button to bring up the multitasking tray, and then sliding from left to-right on the tray. The rotation-lock icon appears as a circular arrow. When the lock is enabled, the circular arrow will have a small lock in the center. To confirm that screen rotation lock is turned on, look in the top right corner of the screen, next to the battery meter, for an icon that looks like a curved arrow surrounding a lock. If you see that, rotation lock is turned on.

To turn it on or off, do the following:

==> In iOS 7 or higher, swipe up from the bottom of the screen to reveal Control Center. (In iOS 6 or lower, double tap the home button on the front of the iPhone or iPod touch. This will reveal the fast app switcher row of apps at the bottom of the screen).


==> In iOS 7, tap the lock-and-curved-arrow icon. If it is white, it's on; black and it's off


==> In iOS 6 or earlier, swipe left to right to reveal the Music app, music player controls, and on the far left, an app with a curved arrow in it (if the lock is turned on, you'll see the lock inside the arrow)


==> To turn screen rotation lock on, tap the curved arrow icon so that the lock appears


==> To turn screen rotation lock off, tap the icon so that the lock disappears


==> When you're done in either version of the iOS, single tap the home button and you'll be returned to normal operation of your device.

==>If this doesn’t fix your locked screen, then there could be a bigger problem. Try doing a hard restart on your iOS device by holding down the Home and Sleep/Wake buttons for a few seconds until the device restarts. Release the buttons when you see the Apple logo.
