"Rattly" Buttons

[Faelach]

Does anyone else have issues with the physical navigation buttons sounding "rattly", and behaving in a "crunchy" manner when pressed?

My phone is in mint condition. It has not been dropped or submerged in water at all since purchase.

I'd go compare it to one of the display units in a store or carrier store... It might be you obsessing over nothing or it could be something physically wrong, like a bit of something broke free and wedged itself in the mechanism somewhere.
