I am reviewing this product on the basis of my 1 year review. display quality of this phone is good. sound and call quality are also good, had no issues with them. camera is decent in this price range. battery life is just about average. performance, this is the point where I got disappointed. for first few months it was smooth, but after it months, it started lagging heavily. I did factory reset, the performance was smooth again but after few weeks, it starts lagging again. gaming performance of this phone is too poor. customer service of samsung is very good(the best in india). I think that this phone has good features in this phone, but certainly it is not the best. those who are brand ambitious can go for this.
