Lenovo vibe k4 note is phone with lot of features and has economic price. If we comapre it with others phone in this range then it has a upper hand but if you are really looking for a very good smart phone then it is not suitable for you. Although it has 3gb ram but it generally hangs a lot . Battery drains out very soon if you are using the internet. I am not satisfied with its front camera, it is blurr. While I am charging this phone and along with that if I am using this then within certain period of time it gets heated up quickly.
If you are really looking for a good quality phone then it is not up to the mark.
