As I am owner of samsung J7 2015 edition and I was using this phone since 6 month. The J7 is great mobile phone under 15k by samsung and best mobile phone for gaming. There is no lagging in playing games like Asphalt 8, Nova 3, Modern Combat 4 etc. I played mostly games on the phone but not noticed any lag when playing. Also the phone was good battery life about 15 hour with normal ( Moderate) usage on 4G network. But there is some of drawbacks of this phone like, brightness sensor, Magnetic sensor, gyroscope does not exist on this smartphone. In other brands lower than this price all above sensor are given with more RAM and with fingerprint sensor. But if u want a decent smartphone and trust of SAMSUNG brand than go for the SAMSUNG J7.
