I own that phone 2 months ago. It has 15 MP primary camera & 8 MP front or selfie camera. Most importantly it has 3 GB which non other Samsung smartphone have in that range. It has 5.5 gorilla glass 4 display. It’s secondary memory can be extended upto 256 GB & also has 16 GB internal memory. It runs on android 6.0.1 marshmallow operating system. May be it will be upgraded to nougat O.S also. It has 1.6 GHz octa core processor. It’s weight is around 170 gm. It has fully aluminium body. It has 2 colour varient gold and black. It look stunning in black colour. It change my smartphone experience, even though it doesn’t hang or lack once till now. This phone has only one drawback i.e his front camera which is not as good as expected. But I m not selfie conscious so this thing doesn’t bother me much. Overall this phone is AWESOME.
