Xiomi redmi 2 prime is the best phone under 7k.
Camera quality is good, 2 gb ram is more than enough, processor is good.
Battery is 2200mah which is enough for everyone.
Compare to Redmi 2 Its internal storage is double(16gb)
There are only two differences between redmi 2 and redmi 2 prime n that is Ram and Internal storage.
I recommend it to everyone.
Just go for it.!
