Samsung Galaxy j2 is an average rating mobile. sound quality is normal as compared to others mobiles . user interface is quite good as all we seen in samsung mobiles. style and design of all samsung mobiles are almost same, there is very little difference between design and size. you can go for REDMEE 3S PRIME at same price range .both mobiles are under 10k but 3s prime give you 3gb ram where as samsung galaxy j2 have 2 gb ram. so you can go for redmee 3s prime .
