My friend has buy this killer phone and I used for a day my experience with it was just awesome.It has great display 5.5 inch full hd which really was looking crisp and the most attractive point I liked is the speaker quality .
It has dual front firing speaker which are fantastic .Many Chinese company are in the competition for k4 note but if you prefer brand than you obviously should go for k4 note .
I also buying it in next sale .
