As I explained in my J7’s review, the J series phone offered by the samsung are not that good.
Samsung’s phones has same design every phone looks similar. There’s only variation in size of the phone.
But this phone has distinct feature. It has a colour ring on its camera which lights up, when you have a notification on your phone or while a incoming call.
Rest other feature are similar with J2 and J5.
Price is higher. As if you would buy a Redmi, Oppo, Vivo at the same price and better features.
