Does your iPhone screen stop rotating when you tilt your smartphone? You can find help here..
All Apple iOS-based mobile devices can rotate the screen automatically when the device is tilted. If this no longer works, accidentally activating the alignment lock is often to blame. How to deactivate this again and what you can do if the screen still does not rotate is explained below.
Some apps do not allow automatic screen rotation on their own . Use another app to see if the rotation works again. The Notes app is also suitable for this purpose, for example.
If this doesn't work, restarting the iPhone can sometimes solve the problem. If that doesn't help either, you should contact Apple Support ..
