A most important change that this new update (80.30.96.80) brings to ZenFone 5Z (ZS620KL) is “Lift to Wake” function. Once you updated to this version, you don’t need to press the power button to unlock your phone. It can recognize your face and unlock when you just lift the phone.
What is new in this update? Asus starts rolling out the FOTA update for ZenFone 5Z (ZS620KL_ WW_80.30.96.80). As always, the firmware update rollout is incremental, so it will take few hours or even few days to reach the OTA on all devices. If you have not received the OTA notification, check for the update manually. To do so, go to Settings > System > System updates to check for the update. Manual Installation: Experienced users can install the update manually. ASUS has made available full firmware for download, if you cannot install the OTA. Suggest to backup data before starting the software update. Check this guide or this guide for reference. [Source]
