First of all, Lenovo is providing a great device at a price of Rs 13, 499 . But, there are consequences as well. This device is only meant for people who like to flash new ROMS and experiment with their device. If you are not that time of person, do not buy this device.
I purchased this device in August from Amazon and the device is very beautiful in design. I also purchased a Back Cover and a Tempered Glass( I broke my last phone after dropping it). Make sure you buy a cover along with the device.
Coming to device, this device is a best. Games and Videos play without any lag(Thanks to the 3GB RAM) . Internal storage is 64GB(you will get around 54GB) .
The Cm 12.1(official) has too many bugs . I flashed CM 13 and now I am happy with the device. Make sure you manually flash Cm13 to the Zuk Z1 for better performance.
Fingerprint sensor stopped working after a month. It is not of good quality.
So, this is my review about the Lenovo Zuk Z1 . Hope you liked it:)
