I bought my Evo 4G on EBay. I've had it for a month and everything is working great. But I noticed the screen corner near the home button seems to be separated from the phone body; all other corners are solidly in place. I can push it in if I press slightly and it even makes a slight sound, but has no negative side effect otherwise.

Just wondering if anyone else has this problem, for how long, what kind of further problems it caused (such as dust under the screen), and whether they did anything to fix it.

P.S. I've googled the issue and know it's common.
