Xiaomi Radmi Note 3 is one of the best phone under 12000 rupee. Build quality is very good since it has metallic body. Battery life, front and rear camera, user interface, call quality, processing speed and so many things are very good in this price range. It has fingerprint sensor which is very responsive. I am using this phone since may 2016 and I faced no issue. In this phone MIUI provides many ease of use. This phone is the value for money.
