If your iPhone suddenly starts refusing to rotate its screen no matter how much you spin the device around, it may not necessarily be due to a bug or hardware issue.

How to lock or unlock screen rotation on your iPhone or iPad If you want to flip your screen around, swipe down from the top-right of the home screen. This will open Control Center.

Go to Settings, General, then under Use Side Switch To, select Lock Rotation. Once enabled, you can flip the switch to lock iPad screen orientation without needing to use Control Center.
