The Android 12 update for the Samsung Galaxy Tab A8 is slowly starting to spread throughout Europe, where the roll out started before the weekend according to Sammobile.
And as often is the case, the rollout started with the SM-205X 4G LTE version first.
But I saw that both cellular and 4G models of the Samsung Galaxy Tab A8 were re-certified with Android 12 through the Wi-Fi Certification body back in June, so the Wi-Fi version SM-X200 will get the update too.

For the Tab A8 the update also includes an update to the One UI 4.0 user interface.
As such, the user manual (PDF) was renewed last week to reflect the latest changes to the tablet too.
