Hiii friends now I am sharing with you my personal experience about lenovo zuk z1,
I used this mobile more than 1 year, I had complaints in this phone was heating when I charge the phone, and hangs some times. Its ram and internal memory is good but there are no space for external memory card. I like this phone but not happy with this product. company need to improve these kind of problems, its camera quality is good. I had problem with its signal strength. Some times my network is sudden disappear for few minutes. After updation of its software I am not able to use its touch sensor. It is really a worst phone ever.
