Burn marks

To follow up, Why don’t you just ask if there’s a solution. Maybe someone who does not have the problem knows what to do about it.

But to answer your question, I’ve been reading and responding about iPhones for 13 years, and I have never seen another post with the problem you describe, and I’m not even sure from your description what the problem is. Why don’t you post a photo of it?

No.

With around 2 billion iPhone users it’s possible that someone else has, but how does knowing that help you solve your problem?

i have a small burn looking spot at the bottom left corner. Has never been there till I woke up this morning.

Can you post a photo?
