For so long, the ZUK Z1 did not update the android systems, but now the company seems to be fulfilling the promise to its users. The company claims that the ZUK Z1 would be updating their firmware to ZUI 2.5.330. Post this, the android 7.0 update will also be pushed to the ZUK Z1 as per the company claims. This will be the first Android 7.0 upgrade to the ZUK devices running on snapdragon 801 devices.
Since the release in August 2015, the ZUK Z1 has been frequently updating their system firmware and maintaining stability. At the end of 2016, the ZUK official also promised their users that the Android 7.0 update would be coming to the device. The commitment that the ZUK officials made to their users back then has now been honored. It is also told that additional future updates will be focused toward fixing bugs in the firmware.
