Lenovo k4 note is one of the best phone I have seen under the price range of 10k to 12k, mid range phone.
I am writing this review after using this phone for more than 2 months. I got this phone for Rs.10000.
This phone has got a curvy design which makes it easy to handle and gives a better grip. At back side it has a 13 mega pixel camera with a dual LED flash.
Just below the camera there is a finger print sensor which is quite sensitive and works even better than expectations. Front camera is of 5 mega pixel and gives a nice picture quality. Screen size is 5.5 inch and has a got a better touch response.
I found no lagging or hanging issue till now. Its sound quality is best as it has got dolby feature.
Phone works on Android lollipop but can be updated in marshmallow. Battery is descent with 3300 Mah.
Overall : camera quality is good, touch is nice, no lagging, battery is quiet descent.
