It is a very good phone . My personal experiences about lenovo vive k4 Note Because I am using now before six months no problems no any issues. work fast and most important fact is speaker quality is too good. Also camera, display, battery all are too good. My thinking is it is a best mobile in this price. Thanks to lenovo for this model this is really a good one. I love it
