The redmi 2 prime has some more features compare redmi 2.
The first thing which I want to tell that it has 16 gb internal storage.
Otherwise you got the same features of redmi 2.
The 4.7 display having 720p resolution.
The phone come with dual Sim with dual standby. Both of the Sim 4g supportable.
The 2200 mah battery is not good thing with these features.
The user interface is also different.
The android version is also the older one 4.4 kit Kate.
I give 7 out of 10 to the phone
