I have purchsed lenovo vibe k4 note 2 months ago. As I was a samsung user at that time, I have littlebit insecurity about this model, but after starting using it , it was very nice feeling.The interface is very attractive and the brightness of the product is very very good.The weight of the mobile is littlebit more but it is adjustable.It also come up with the Dolby sound system and two speakers at the front side which provide good sound quality.The fingerprint censor, camera quality, touch screen, and battery quality and battery standby time is very good.It has also very nice functions like super power, NFC , night mode , cast screen , wide touch.
Overall very handy mobile which is in budget.
