Motorola V551 / V330 / V547 / V555 / V557

Ok, so last night I really needed to charge my phone but I was expecting a call... so I plugged it to the carger -which I don't normally do, I always turn phone off to charge- anyway, i had my BT headset was paired to the phone, once I plugged the phone to the charger something weird happened. My phone would say they were paired but whenever I got a call I would say hello, but there was nothing but dead air on the other end. I called that person back but I couldn't hear anything on the other end (NADA). I was like ok, so I unplugged the phone from charger, still nothing. In order to fix this mess I had to reboot phone and pair them again. Is this a bug? or is it just not possible to use BT headset while it's charging? I've had this phone sin...
