Asus starts pushing out Android 8.0 Oreo for ZenFone 4
The update was released on December 29, so it may take up to a week to arrive on all ZenFone 4 devices. Be patient if it doesn't show up right away, but you can try to manually pull the update in a few days.
Obviously, picture-in-picture mode, autofill, smart text selection, and notification dots are all there as well. It's also worth mentioning Asus ZenFone 4 users will now be able to install apps from unknown sources: “hostile downloader apps can't operate without permission; users now permit the installation of APKs per-source.”
