Something under the screen

I noticed yesterdays on the edge of the screen something that looked like liquid almost. I thought it was something under my screen protected but it's not, it under the screen. When you like push that spot it seems to get worse. I know it's not water or anything because I'm really carefull with it. It also looks like it is doing it on the other side of
the screen a bit too. I believe that it is the glue or adhesive they yous to keep it on the phone because I know that my friend had the old Voyager and hers actually started peeling off.

I don't believe my phone is under warranty anymore but would they still replace it?

I have an upgrade I can use, but I love this phone and i think it would be stupid to use the upgrade to get the same phone. I was thinking about the Alias 2 but I'm not sure if it's a good phone or not.
