I bought a 4g 32gb a couple of days ago. I checked for light leaks and loose screen and it was all perfect. After using it for a couple days, this is minor light leak on the screen where the volume buttons are. However my biggest concern is the top left corner right of the screen above the volume buttons seems to be lifting up a little. I can feel that area heat up the most during heavy usage so I think the heat is causing the glue to fail and the screen to lift. It's not really that noticable but I can definately feel it when pressing down on that area. So is that supposed to be normal after that area heats up for a while? I think this problem is also causing some minor light leakage.
