I bought a Samsung Galaxy J7 2015 about 7 months ago . It was a giant phone for me after using the Samsung galaxy s4. It also has a fabulous camera 13mp rear with full hd video recording and 5mp front with front facing flash light that was awesome I had never a selfie camera like taht ever. It is a super fast phone with 1.5 ghz quad core processor . It never lagged and always pleased me. It was my first experience of 4g speed with the j7 bcoZz it is 4g duos and as an Indian I got a 4g Airtel sim with 3 months 4 gb data free. I also played heavy games like nova 3 , combat 5 black , Asphalt 8 airborne , calsh of clans but then too it never slowed down. Even after 7 months I’m satisfied with my mid range super phone The Samsung Galaxy J7.
