LG VX-4600

I thought this phone was a really great product at first until recenly I have had a million promblems with it. I wanted to know has anyone experienced the same problems I have. For example this phone turns off by itself for no reason ( Battery is fully charged and the signal strength is full); and when the phone turns off you have to take the battery completely off to reset the phone. Since this was the second phone I have had of this make and model today I traded it in for the LGVX6000 hopefully this will be a better phone. 🙄
