It is one of the few ASUS phones to receive Android 10
ASUS is working on rolling out Android 10 to its phones, and the ZenFone 5Z gets first dibs at it. While this is the second beta build (the first one rolled out last August but was limited to select ZenFone 5Z userS), this update (v100.04.44.67) is available to all ZenFone 5Z users who want to try out Android 10 on their phones.
The ZenUI6-based update removes most bloatware apps and provides a near-stock experience. In addition, the changelog notes the addition of native Android 10 features such as system-wide dark mode and gesture navigation.
