Samsung Galaxy Grand Prime 4G is a good phone, but in 2016 it does not reach to the marks of a good budget phone, as it comes with a 5 inch screen which has a resolution of 540x960px which comes down to 220 ppi which is very low as compared to phones under this price bracket and as we talk about chipset is has Snapdragon 410, which is 64 bit chipset and it is a dual sim phone which has a support for 4G network as well, which is really good now a days, it comes with 4.4.4 Android kitkat out of the box which is poor as compared to other phones now a days, it comes with 1gb ram and 8 gb internal storage and with memory card slot as will, which is a good thing and a 2600 mah battery, which is below avg.
The main disadvantage of this phone is that, it has no glass protection in front, it has normal glass and it does not have auto brightness.
So in the end the value of the phone for me is 5000 Rs, not more then that because now a days you will get phones with 2 gb ram and with a fingar print senser as well, under this price bracket.
