Why are photos taken in landscape show only in portrait

Hello, Dmohring.

Thanks for posting in Apple Support Communities. If we understand correctly, you are unable to view your landscape photos in landscape mode on your iPhone.

Is Portrait Orientation Lock enabled on your iPhone? Here's how to check: Rotate the screen on your iPhone or iPod touch - Apple Support

Let us know. Take care.

Happy to hear that, Dmohring.

Cheers!
