Lenovo's ZUK Z1 will be launched internationally running Cyanogen OS 12.1
The international version of the ZUK Z1 will run Cyanogen OS 12.1 (based on Android Lollipop), thus being different from the Chinese model, which runs a version of Android Lollipop tailored for China.
Different software aside, the international ZUK Z1 will be similar to the device that's sold in China. Thus, it's going to be powered by a quad-core Snapdragon 801 processor (not the newest chipset around, we know), while sporting a 5.5-inch display with 1080 x 1920 pixels. Furthermore, the handset will feature LTE, fingerprint scanner, a 13 MP rear camera, 8 MP front-facing camera, 3 GB of RAM, 64 GB of internal memory, USB Type-C port, and a very generous 4100 mAh battery.
We don't know exactly where the ZUK Z1 will be available around the world, and neither for what price. But we can tell you that the smartphone's Chinese version costs around $285. ZUK will announce more about the global Z1 on August 21.
