I useing this phone from last 8 months.
I am totally sa5isfied with result.
Samsung gives us
5.9mm thin phone and I guess it is the one of the thinnest from samsung.
It has 32 bit exynois 5430 chipset octa core cpu
32gb memory
Hybrid sf card slot
Dual sim phone
Now it has marshmalllw update which improves battery life.
Also samsung gives 16 mp rear camera which delivers very good performance at this price range.
For security reasons fingure print scanner also available in this phone.
So overall this is best phone I ever used it never lags.
And last but not list super amoled display I am biggest fan of this kind of display
