Black shadow-like lines on rear camera
So this morning when I got up, I went to take a photo of something and saw these shadow like lines. I haven’t dropped my phone recently so I don’t have any clue as to what’s causing it. I have tried cleaning the lens and restarting my phone multiple times and nothing seems to work. I’ve been reading around trying to find out what it is and what could have caused it, but so far no answers, only people with the same issue. I don’t know what to do with the phone as I got it brand new in August 2020.
Any help would be appreciated
