Actually, Mi products are the best thing to talk about. It has so many good features which comes up with a low cost itself. But this note 4 has many faults as everyone talk about it as its a bomb ?? like cell phone which blasts and all those. Even I am facing such a similar problem as its charger and audio headphone jack has been destroyed so early from mobile purchased date. So if they keep up the good progress by maintaining such problems it will be a better company in cell phone brands as I can say.
