Hi, Help!! My phone has gone a bit bonkers the last couple of days. When I try an make calls the green call button won't work. I've turned the phone off and on, taking out the battery etc but am reluctant to reset the factory setting because,I will lose a lot of stuff. When I do manage to get it working I might get through but it will suddenly call another person and put my current call on hold. Then cut both off. It normally calls somebody that I might have attempted to call earlier (I think it is hanging). I can do everything else but make calls. It's happened 3 times today and I couldn't call for about 30 mins yesterday. When I did replace the battery the clock went to 00:00 and the date went back to 1980. Slowly everything started to go back to normal and eventually I could make calls. I've deleted applications to free up memory. The button regularly lag too. So if I'm typing a text the buttons don't react and then they all suddenly come up at once and catch up with me. I don't want to buy another phone! Can anyone help?
