Samsung j7 is worst moblie I every seen as it is made by samsung. Offering cheap quality of product with good features is the type of samsung. I have buy J7 last month as it is samsung it started showing promblem. Whenever I used phone for 15 min or more it restarts automically and phone lags very badly. not even I used for year it started showimg their true colours.And most important part is customer service and service center ius most worst than phone. Sound quality of phone worst than ever. The only postive thing about phone is camera which goes in J7 side.Never buy samsung products.
