The back and off buttons on my new AT&T Samsung Eternity feel like they are loose and they keep squeaking. It is so annoying. I just don't want them to pop off and then have to pay $50 to replace the phone.

I have already exchanged the Eternity the day I got it because it had about 6 dead/stuck pixels scattered across the screen (ikr o.o). Do you think my problem is bad enough to exchange it? I called and they said I could exchange only once, but if there's a problem I could possibly exchange it. Do you think they will make an exception?

(I'm still in the 30 day period, but I have already done one exchange because of hardware issues.)
