iPhone 7/Plus Lines across lens in portrait mode or zooming in

[hpdv2000t]

I've had my iPhone 7+ for just over a year. About two weeks ago, I noticed that when shooting photos in portrait mode I have strange lines appearing on screen. Please see attached image. They also come up in regular mode when I try to zoom in beyond a certain point (about x2), though oddly sometimes this doesn't happen. No problems when shooting videos when zooming in or out, or when shooting photos without using zoom. What might be the issue? Thanks for your feedback.

Looks like a shadow. Is typical of all of your images or just portrait mode. Is that also discoloration I am seeing?

Only in portrait mode and when zooming in. And yes, there is also discoloration, thanks for pointing it out.

Looks like the reflections of a cracked saphire lens.
