I purchase this lenovo zuk z1 for rupees 13499 at amazon 4 months back this is a good phone as a bad phone in different conditions
1 .bad operating system comes with cynogen mod
It has lots of bugs some time it really make irritetes
Never get updates never ever
Cynogen mod goes shutdown by company
Didnt support many apps like gta series by playstore etc
It takes more battery and it makes heating up problem
so I recommended search another smart phone in the market which dont have bugs atleast.
Redmi offers such a great phones
Etc
