Hey Guys J7 2016 is not the best. The are many more phones that are much cheaper with with some latest features like IR blaster. So I suggest u that you must see the other phones in comparision. Or if u want to go in samsung then u can take J7 prime .
I am using a J7 6 and truely I am not satisfied with its performance as it lags. It only has 1.5 gb ram .
Not only configs but the look of the phone 8s not that plesent. It is a good budget phone from samsung.but the market is open and u can find much better competers for this range like
Asus Zenphone 3 , remi note three, redmi note 4 .
So just see that if ur needs are satisfied by this config then buy this.
Is a good phone for nominal use.
