Inner frame lifted

I just noticed the bezel (i think) lifted on the left side of the crease but it's nothing dramatic, like it doesn't prevent the phone from closing or cause anything else. i'm assuming it happened because of the heat in my apartment and due it it being very damp... it's just lifted and not sitting tight in its place.

Well my question is: Is it really that big of a deal like the others here made it out to be and should i be worried? i dont have any warranty left and honestly can't be bothered to get it repaired for this. I was planning on using the flip5 until it dies and then switch back to slab phones.

How long can I rest assured until it turns out to be problematic for me? Can I calculate with, around 7months-1 year?

Thanks in advance
