I had used samsung galaxy j 7 for 6 month. It is very good. The look and the design of the mobile is very attractive. It is very slim. Sound quality is very good and clear. It has 5.5 inch super amoled display with 16 m color depth.it has 2 gb ram and 1.6gh octa core prosesor which has very good speed. It has 13 mp back camera with auto focus and 5 mp front camera . It is dual sim handset with 4g sim acceptable. It has 33000mah battry which is long backup. Its look is very beautiful. You goy 1 year warranty of handset and 6 months warranty of accessories of mobile. Lastly I would say that the mobile is very very good and have great features.
