I am not a Samsung franchise but I am using it this from past 3 years it is free of lag it comes with 1.5 GB ram and 8 GB internal memory with 64 GB expandable memory it has a 13 megapixel rear camera with autofocus focus and 5 megapixel front camera with a long lasting 3000 MH battery and large display 138. 6 mm ( 5.5 inch) pre- installed with 14 regional languages, 1.2 gigahertz Quad Core processor and also LTE cat4 and volte calling supportable. The only cause I found in this phone is 8 GB internal memory in one portion of memory is occupied by heavily existing content. I think you should go for this device in a affordable budget of 7990 rupees only
