Samsung have only problem in it is that its slows down after some time .
I buyed samsung galaxy on nxt 4 month before and at first it was good but after 3 month it started to slow its speed and it hang also .
It is a problem with every samsung mobile but in this it is more yhan expected it stops working frequently and apps get closed automatically . The important document are not saved because of this . There is 3 gb ram which is good for this type of mobiles but after this also it gets slows down other company give us a good speed compared to on nxt .
This is purely a waste of money .
