Lenovo vibe k4 note is a very good phone, to be honest I don’t own one, but my friend owns this phone, and since we are hostelers, the phone is used in many purposes. Ram is 3gb and this gives a good gaming experience but now a days, 4gb ram phones are also available under this price range. And the most awesome thing about this phone is its sound quality, it has dolby atoms stereo speakers, you feel like you are listening to a mini woofer??. And it also has a fingerprint sensor which is also a plus point. The back is a non removable battery, it can be a pro as well as con according to the buyer, what you prefer. Dual sim 4g volte supported.
