I have bought this smartphone and suffering a big problem. This phone becomes overheat and stops to response touch sensitiveness. I always fall in this problem. It happens if I use this phone just for 10 to 15 minutes. It is an awesome phone but I am being bored for this problem. Sometime the touch screen does not response to command.
My questions:
1. What should I do?
2. Is there any software to reduce this over heating problem?

3. or should I go to repair center? (just tell me if you are sure that it would be solved)
By the way, it doesn't have any warranty.
