Okay, I recently started noticing a weird clicking noise coming from my iphone, usually when I pressed the home button. It seemed like the home button was sticky, and it was making a sort of additional clicking sound combined with the regular click from pressing it. I quickly discovered that the click actually occurred any time I pressed on the back glass of the phone, in the bottom right area. It's hard to really describe, but it basically sounds and feels as though the glass separates from the rest of the back panel in that area of the phone, and I have to press it really hard for it to "re-attach" and stop clicking. It may be my imagination, but it also appears to have something to do with ambient temperature, as if the glue holding the glass melts when it's hot. We've been having a crazy heat wave in california the past few days and I've noticed it a lot more. Anyone else have this problem? I am planning on most likely exchanging for a new phone as soon as the 4.1 JB is released, as I can only imagine that this will get worse with time, not better.
