Phone [Q] Screen glass is sticking off the frame

Hi, I have this rare problem, for now it's in a small glass area, my screen glass is sitcking off the frame, in some part of the middle of the phone. For now is very small, but not a small area, I think it's about 1,5cm.

My question is if it's a common problem. Here in my country Samsung WON'T replace the screen or the phone, they say it's normal when you use it but the won't replace it.
