No doubt Samsung Galaxy J2 is budget phone, As per my Random Market Research Samsung Galaxy J2 is first choice of those persons who wanted a phone with good brand value like Samsung and into budget price.
But if we talk about the Processing of J2 it is not good.
as I already use it , Gaming experience is not good on J2 and one more thing. after the few months battery performence gradualy degrading.
so atlast I will suggest to users that there are many other alternatives into similar price.
