All ZenFone 3 and ZenFone 4 Phones Will Be Upgraded to Android 8.0, Says ASUS

During the event, ASUS announced a total of six ZenFone 4 smartphones with different specs and features, including the ZenFone 4, ZenFone 4 Pro, ZenFone 4 Selfie, ZenFone 4 Selfie Pro, ZenFone 4 Max, and ZenFone 4 Max Pro. All devices are shipping with ASUS’ ZenUI 4.0, which is based on Android 7.0 (Nougat). But wait, because it looks like ASUS promises to upgrade the entire ZenFone 3 series of smartphones as well to Android O. Announced last summer, the ZenFone 3 series come with Android 6.0.1 (Marshmallow) operating system by default, but they’re all upgradable to Android 7.0 (Nougat).
