Not long after the Nokia G21, Nokia Mobile started rolling out Android 12 for its first tablet. The update is not yet available here in Croatia, so I can not tell you much, but some users report that they have received it.
Nokia Mobile has also confirmed that the update has been released for some markets. So check your first Nokia tablet and update it to the latest version OS
It seems Nokia Mobile took a little longer to update its first Unisoc devices, but I am glad they did. I still do not have Android 12 for the G21, which uses the same processor as the T20, and I am curious to see how well it will work
If you have received the update, let us know about your experience with the updated T20.
