Hi guys I am using this xiaomi redmi note 4 from 4 days and I had tested it lot. It has good build quility and gerat in hand fill and has 2.5D curved glass on brezels that feel better in holding in hand. The call reception on this device is pretty much desent and lot more clear also via loudspeaker too. And it is running on miui 8 with 7.0 android version. It user friendly. Let move towards performance it is powered by all new chipset that is snapdragon 625 with octa core processor clocked at 2.0 GHz. With 4 GB of RAM which is good enough for average user it handles most of game too much fine but very heavy games it lags.
But in this price rang it is best device from redmi ever.
