Lenovo viber k4 note will not disappoint you when it come to built quality and sound. Normal mobile users and music lovers without any second thought go for it.
This phone looks awesome and very light weight. Speaker dolby atom speaker is good and voice quality is very good on call. Tow best things which phone makes is killer according to me is it battery working so well and touch is really smooth. Lenovo is a trusted brand I would suggest go for it. : )
