I purchased this model lenovo k4 note 4 months before. I made a brief research on this and It became my best choice among Oppp, vivo, samsung, micromaxx.
Its DOLBY ATMOS sound, style, design are very impressive.
Operation is so friendly that any unknown person can use it in smoother way.
Its having 3 GB RAM which is very sufficient for daily stuffs. Its other features like Wifi, Net connection, camera and all are best compare to the Oppo, Vivo, Samsung, Macromaxx.
Before purchase, I always compare with price, sound, camera, Internal memory, External Memory, Finger Print Scanner. But I found this is best set ever I found in my cost Rs. 12, 000/-.
