For security updates we have minimum 2 years
S4tI remember Asus promising updates till Android 11 for Zenfone 6 during its launch.
About major updates, this phone was released with Android 9 and Android 10 is being tested. Do you know if it will get the next major update (Android 11(?) which should be released next year)?
I'm just trying to understand where this "new" Asus is going. It's nice to see new phones running clean and smooth Android versions, but there are still some question marks about software support.
