Im using this phone since feb 2015 and im soo impressed this this phone that I dont feel like changing it. It is best option available for this price range. Best picture quality, battery backup, performance and what not. This phone has got everything which we cant even imagine for a price of approx. Rs 8000.
Moreover its a 4g phone. The only one thing which this phone lags is dual sim feature as it offers only single sim. Mi has nailed in this flagship, best features ever and the miui 7 with android makes it a best option.
