If you spend 11000 for Lenova k6 than this is your worst decision for you. If you compare to other Smartphone than you find Moto E4 plus, Moto G plus, Panasonic and Xiomi Redmi 4 are provide better feature for this price range.
phone sound quality is good, very user friendly, design for this phone is avera but if you install 10 to 15 app in phone hang problems start. Touch so many times than app open, you write M using keyboard and write N in display that time of problem occurs.
All over for normal user this phone is good.
