This is a most excellent place for technology news and articles.
Samsung's update policy for their lower end models is pretty atrocious. While on paper they offer updates for a couple of years, it you look more closely, you'll notice that the update intervals get larger and larger as time goes on. You might not get important updates for half a year. Sure, still better than not updates at all, but a pretty awful policy for security updates.
Makes sense. I suspect they're selling more of those overall so they like replacing them more often. The only reason they're providing longer support for the S-series is because someone else does too. They have made their own SoC (Exynos) for more than a decade and there wasn't anyone stopping them supporting the models with that SoC for longer. They didn't.
