As we all know xiaomi redmi note 3 launched last year is still a market king.this phone is one of the best phones under 12k.i m using this phone since three months and the company really stands on its words.its performance is really outstanding and what to say about its gaming quality is really good, it comes with a 16mp rare camera which does its work excillently in day light but step back in night, the front camera is good even in night, it comes with OS 5. lolipop and is upgradeable to 6.0.1 marshmallow which is a good point, it comes in two varients 16gb and 32gb but both the varients works excillently.so if you r in search of a phone under 12k then this is the phone made for u.
