I have searched for this and can't seem to find a consistent theme ... just in the past few days, my T600 (VZW) has been not ringing when a phone call comes in (but not always), and many times not vibrating either when set to "vibrate" (but again, not always).

Other times, it vibrates "1/2 way" (if you know what I mean), other times, it operates perfectly normally ...

I am sure I have seen threads on this, but can't seem to find them. Is this a sign of a larger problem, what have others done? Is this worthy of replacement (about 60 days old)
