Let me start from the point when I bought the mobile for the first time. I was very excited for it but after less than a month, i started getting replys from this samsung piece. It was so that it showed tremendious problem on the following aspects-1) firstly it started functioning slowly and started giving rough calls when connected to internet.2) Secondly another demerit was that it started showing battery problems and started overheating frequently. Though it looked well and had a stylish design, it could not satisfy its value for money.As per me, it was not user friendly and troubled me a lot.
