Phone display when phone is rotated

Hello JJGMD,

Thanks for posting in the Apple Support Communities. We're happy to look into this with you. Is it possible that you've locked the screen so it can't rotate? If you're not sure, check out the information below to check for this.

Rotate the screen on your iPhone or iPod touch

Rotate the screen on an iPhone without a Home button

1. Swipe down from the top-right corner of your screen to open Control Center.

2. Tap the Portrait Orientation Lock button  to make sure that it's off.

3. Turn your iPhone sideways.

If the screen still doesn't rotate, try a different app — like Safari or Messages — which are known to work in landscape mode.
