Sprint TP2 having problems answering call

[jawe347]

I'm running stock rom on Sprint TP2. I have the Plantronics bluetooth piece. A problem that I am having is that when a call comes in, whether I answer it with the bluetooth or the hard keys the phone does not answer the call. It lingers and eventually goes as a missed call. Sometimes if I answer with my bluetooth and the caller stays on the line the phone eventually answers the call. I've already been to the sprint store once and did a hard reset. This is still happening. It is annoying as F*ck to say the least. Any suggestions anyone?
