I bought this mobile in 2015 and I felt no issues till now. It is the good budget phone in the market available right now. Lets talk about it.
Well if see the design it is classic like others samsung devices has. It comes with Android Kit kat version upgradable to lollipop and the UI is Touchwiz. I am specially impressed by its hardware performance. It has only 1.3 GHz Exynos quad core processor and 1GB of RAM which performs like a pro. If you are a average user then its going to be fits on you. Also you feel friendly with it because of its smooth functioning and well developed Touchwiz UI.
In my view it is a good average using smartphone for a average user person and I also do not prefer it for those who is thinking to buy it for gaming or heavy using.
