I've just begun to notice this on my refurb! I've had the C-thruFone live wallpaper now for awhile, but haven't used it on this one. I just turned it on, went to my homescreen, then, something odd. As I hit my home key, I felt the phone click, and heard a little click. I opened up an app to get off the homescreen.... and there it was again! As the home screen went away, the click, both audible and physical happened! I opened up the camera app (from a different menu, away from the homescreen) and omgwtfbbq there it is again! My other Evo (my first one) with it's plethora of issues didn't have this I'm sure of it... the image quality on this one is identical to my first one, there are no problems with motion blur, etc., but it's just making this funny little click click click every time the camera is being throw into or out of use. I can feel the click through a Seido Active case.... whatever they are (rubber bottom, hard plastic outer case) very distinctly. Do any of ya'll's do that?
