This is the smartest set of Samsung I ever seen.It has 13 mp rear camera with an internal memory of 16GB. It has an excellent slim look with an awesome screen size of 5.5 inch. I have been using this phone since last september and the most amazing feature is that it never got hang even once since I purchased this phone. It has expandable memory up to 128 GB which makes it a very attractive mobile phone. It’s RAM is 2 GB which keeps it enough fast. It’s processor is also very much good. So, I would like to recommend this set .
