Recently purchased one from flipkart. Phone looks good and slim. Camera & flash on top at left corner. In backside bottom, Mi's brand logo. Good to see Make In India mark on phone. Good sound quality with speaker and also during call. It gives exiting MI's own UI, got update of UI8. Phone comes with Android 's 6.01 operating system. Model includes 2G, 3G and 4G LTE signal receiving. Best part is it's battery that is 4100mAh that gives backup upto 24 hrs after full charge, so it's like charge it and forget charger for next 24 hrs. Con of phone is with it's back cover which is unrecoverable and if fall than will dent due to metal. It works fine with iPhone headphones. Each rupee you spend on this mobile is useful on these phone.
