It was my first 4g phone, And as ussual I got the best one, By the best of my luck, firstly I thought about RS 14700 in which I got it but after keenly useing it I feel that was really a good deal for me, Firstly its battery backup is owesome 3000 amph and camera both front and rear are also outstanding 16mps and 13 mps, and the inbuild memory of 16 gb.sound quality is also a great and unique like it soft flow also makes it best, But there is one problem with Samsung he management had made more two model’s one after another.not with a big difference.
