Iphone 11 photos all have a fuzzy "glow"

It was a waterproof case, so it did have clear plastic over the camera. My photos were fine when I first put the case on. So I think maybe it came in contact with some nail polish remover or some other chemical that damaged the plastic, because cleaning it didn't help. But the camera has been working fine since I put the new case on. Thanks so much for your assistance.

Apparently, the phone cover came into contact with something that damaged the clear plastic covering the camera. Cleaning it did not resolve the problem. But a new cell phone case worked.

I don't know. I just recently noticed the problem. I don't take a lot of photos, so it'd been a long while. I used my iPad to take photos today and they looked amazing! So I'm thinking it might have something to do with the phone case. I've ordered a new one and will try the camera with no case and then with the new case to see if that makes any difference. Otherwise, maybe I accidentally changed some settings I didn't know about. The really good photos I've taken in the past were with my old phone, before this one. So maybe it's just this phone or this OS. Any advice or things I can try would be greatly appreciated.
