Redmi 2 prime is the best opotion under 7k ruppes.it is avery good smartphone .it’s camera is good.performance is good.it is one of the best phone.it is comes with 8mp camera with bsi sensor.that is cool.it also available 1gb and 2gb ram opotion .I like the 2gb ram opotion because the 2gb ram makes multitasking faster smoother and also greater.the only thing that I noticed that the phone has android 4.4 kitkat.if it has lollipop it would be better.i advice it is a good phone and you can pick it for yourself.
