Galaxy J7 is an amazing phone with a smart rate. For the past 6 months I am using it. The battery backup is very good. Even though the net is switched on for the full day, a minimum of 30% charge remains. The screen size and resolution is very nice. Have not felt any negative feedback on this particular set. Overall its the best set at the best rate.Capitalising their popularity, the company also recently launched the Galaxy J5 Prime and Galaxy J7 Prime smartphones. Of the two, we received the Galaxy J7 Prime for review.
