Yeah, I have the same problem except it only does it when I'm using the phone, doesn't do it while it charges. I also noticed that it began doing it after I enabled the bluetooth. Do you use the bluetooth feature? Also gramma4health, does your phone actually store your recent calls? When I make/receive/miss a call, it does not record it on the phone. Everytime I want to call the last # I dialed, I press talk to dial it and it says recent call history empty.
