Well from what I can remember This phone was release almost at the end of july and I bought it in between august .For first few day the device worked perfectly good and let me you about it specification
It has 13mp front and back camera
Its is octacore with 2.35GhZ processor with 3gb ram
Its is 5.7 inch when measure diagonally
Its has finger print sensor and has two sim slots with botj of them having LTE+LTE support
It has android nougat support and it is said that it will receive more updates soon
Its has OTG support and internal storage of 64gb and can be expanded to 256gb.
Now let tell you why it is so-so product well after few days of usage like any other samsung product it started to hang and when ever I used it while charging most of time it hanged and started to shutdown.And my second reason is its price it is very costly for its price range(20000).And same feature can be available at lower price.Well I am uploading some of its pics
