Hii I use this mobile and Iam very much pleased to have this mobile. Actually I doesnt like Samsung mobiles because many of my friends, relatives mobile used yo hang after they are used for 6 odd months but after using J7 I changed my opinion.
The mobile looks stylish and the Camera is also good.
->Battery life is main advantage because I play game for hours still mobile charge percentage is not effected as if we get in other mobiles.
->Only defect is average sound system.
-> Used it for more than year and still using it but doesnt hang at all so I loved it.
