Lenovo vibe k4 note is an excellent phone as the budget and the features are also good. It has 5.5 inch FULL HD display with 401ppi, so u can watch full hd videos on it. It looks good it has 3gb of ram with 16 gb internal storage in which you will get 10gb of space for use. You can play games but not the big game because the graphics was not that good. But when we talk about its sound quality, then its just awesome over speaker as well as in earphones because of its dolby atmos feature. This phone has 3300 mah battery but then also it does not last for a day while working. Design was average. It comes with 5.1 Version, lollipop, now it was update to 6.1version, marshmallow. The phone has 13mp rear camera with dual led flash which is really good the pictures are clear and crisp and the front camera is of 5mp with beauty mode but then also it is not up to the mark so the selfie camera is ok for me. It has finger print unlocking system which is really a good feature at this price and its finger print sense works very fast. This phone doesn’t heat alot i’m saying this becouse i’m using this phone since last 6 months. So over all this is a good smart phone with budget and features.
