As I m addict of big display with awesome picture quality and pixels. I bought samsung J7 slik design just 5 months before and since then I got no complain in it like sound reception and any other. its fast processor with 2 gb ram make it a durable device for games watching movies and many more.
Rest of all this its 13 mega pixcel cam and 5 mega pixcel front cam has awesome picture quality for online chat and for making photos. It is the best reward of ur spent money no doubt.
