Samsung J2 was an average phone not too good like J7 model. Design of these phone was not good. It has problem of hanging. It doesn’t support high configration game.
Camera quality was average. But the battery life of phone was great you can use it approximatly 2 days. Some new features added in these phone like altra data saving mode and altra battery saving mode which is very useful in todays life. I don’t prefer to use these because at this price too much option is available in market.
