Samsung galaxy is one of the best mobile I ever used. It has good battery back up 3000 m-ah. The sound Reception is quite good and clear. The Samsung galaxy On7 is very easy to use and its very user friendly. The style of the mobile is very classy and has a H.D screen of 5.5 inch. And the design is very slim. The best thing is that the cost of the mobile is very cheap. It has a good camera quality front is of 5 mega pick cell and back camera is of 13 mega pick cell, which click a very nice picture. It has a 8 Gb internal memory. And has a 1.5 Gb of Ram. The only corn in this mobile is Ram as its ram is low. They are available in different colors. I am using this mobile from last 7 months it is one the best mobile is lower price. I will give 4/5 stars rating. I strongly recommend every one to buy this mobile. As it is one of the best mobiles to use.
