Hello friends the samsung galaxy j7 duo is not a worth product as I say in the title. I have personally used it it only have 4gb of ram amd 64gb of internal storage in such expencive price which is Rs.16500. And it also don’t comes with a finger print scanner and a face ditacter. It supports otg and 4g network. But it’s too expensive bro. So according to me don’t buy it .
