Green line on the bottom of photos - iphone 15 pro max

Hello everyone,

just wanted to share an issue with my current iphone 15 pro max.

when scrolling thru camera pictures a green line appears on the bottom of the photos. it's just on the photos, not in the screen itself as it does not appear in any other screen.

I did some tries and here's what I found:

• it appears on all the photos shoot with the iphonw both portrait and landscape; not in screenshots or other images.
• it disappears after zooming in
• it's only on recent photos
• it happens only after shooting in raw format

do you think it's a ios issue or an hardware problem ?

I attach here below an example

thanks and best regards
