I buyed this phone last year 2015 december, for my dad, believe me it is the one of the best phone of xiaomi around 7k.
My dad using this phone, and I’ve been using now, we have got no issues with this phone.
I dropped this phone twice, no problems I’ve got.
And the main part of this phone is good camera .
You won’t get in any phone which 20k also, but Redimi 2 prime camera gives you good pictures, back and front it gives you superb photos.
Compatible in hand.Budget oriented phone , go for it.
