Asus upgrades the ZenFone 6 to Android 11
Upgrading to Android 11 on the ZenFone 6 also requires a back-up of all user data, especially if the user wants to downgrade back to the previous version. It also gets rid of Avast scanning software that had been on the phone, as well as some features such as ZenUI Help.
Unfortunately, the update is only available in the Taiwanese market at present. In addition, Asus has announced that it will only hit so many users at a time, possibly to manage the risk of major bugs prior to a global roll-out.
