Lenovo-backed ZUK recently entered the fast-growing smartphone market with the launch of ZUK Z1 in China. The handset grew quickly in popularity, thanks to its impressive specifications at an attractive price range. ZUK Z1 runs company's own ZUI in China, while the international variants are powered by Android 5.1.1 Lollipop-based Cyanogen OS 12.1 OS.

With all major companies rolling out Google's latest Android 6.0 Marshmallow for their devices, ZUK Z1 users were left wondering on the status of their software update. But the company's co-founder Chen YU has no plans on keeping its customers in the dark. Yu confirmed that the company is currently working on a new ZUI OS based on Android 6.0 Marshmallow, Uber Gizmo reports.

The new software rollout is expected to begin around the Chinese New Year, which falls on 8 February, 2016. Currently, there is no time frame as to when the international variant of the ZUK Z1 will receive the latest software, which is Cyanogen OS 13 based on Android 6.0 Marshmallow. But it is still a long shot as the custom ROM maker is still working on the Cyanogen OS 13.

ZUK Z1 made itself quite a name with its 5.5-inch Full HD display, fingerprint scanner-integrated Home button, USB Type-C port, dual SIM support, 13-megapixel Sony Exmore RS sensor with f/2.2 aperture, OIS and dual LED flash and an 8MP front snapper. The handset packs an impressive 4,100mAh battery and still manages to stay 8.9mm thick.

In China, the ZUK Z1 is priced at ¥1700 (around Rs. 17,860) but there is no information on when the handset will be launched in India. There is a lot of potential for the feature-heavy, efficiently-priced handset in India, which has become one of the major markets for several smartphone makers.
