I am using this phone from Past one and a half year.Samsung Brand is very good.It comes with 3GB RAM making easy to do multiple tasks( atleast 2, not more) .Battery is good with 3300 mAh maybe there are many other phones available with better Battery.Camera is decent.
Negatives: Rarely it hangs, Battery is OK don't buy this if you want very good battery phone, Sometimes there will be problem in call connecting.
