I have a problem with my nokia c7. Well the problem is that the screen sometimes hangs while working on it. I thought this could be due to a lot of applications installed in the phone. So thatís why I removed certain application in the phone. After that I thought that the problem will not be repeated but it again gave the same problem. When I started working the screen started hanging again. Whenever I am in 3G, the phone gets restarted automatically and this happens quite a few times. So can you explain me what can be the problem here.
