I doubt that mid rangers like A series will get more than 2 main Android updates. If they give consistently 2 main OS updates + 3 years security patch that will be big thing. A51, A71 were launched with Android 10 out of box so they can expect to be updated to Android 11 and 12. A50s, A70s were launched with Android 9 and mostly will get update till Android 11. A80, A90 are different that they have higher specs but I don't expect Samsung to update them beyond Android 11.
