Is anyone experiencing some "clicking" or "skipping" or something with their haptic feedback (vibration), particularly noticeable when typing? For me, it's as if there's static in the vibration, if that makes any sense, that manifest as sort of a clicking noise. It's just annoying enough to bother me when typing long messages and email and such. If others have it and it's "normal," I can live with it. If it's a harbinger of future vibration failure, then I'm going to swap mine out. Which is a pain, of course, in general, and something I'd rather avoid. This and some general creakiness from the battery cover are my only issues with the phone.
