According to the latest developments, Samsung's Galaxy S8 and S8+ devices will no longer receive updates. This means that owners will have to adapt to the current state of their software if they intend to continue using their devices.

As DroidLife, the old base models are no longer included in the list of devices receiving security updates. The Galaxy S8 Active and S8 Lite are still on the list for now, but it's worth noting that they were released months later than the main S8 phones.

It's no surprise that Samsung has decided to stop pushing updates to the devices. When they first launched, they were a huge hit, giving Samsung the best pre-order numbers it had ever seen up until that point. However, it's been over four years since the phones were released - even Google doesn't support Pixel for that long. The S8 phones received monthly updates for three years, but Samsung gave pretty much everyone a heads-up that it would soon stop supporting the devices when it put them on its quarterly security update schedule last year.

At this point, the oldest Samsung flagships still receiving monthly security updates are the Galaxy S10. The Galaxy S9 and S9+ phones are on the quarterly security update schedule and will likely receive updates for another year before the tech giant stops supporting them as well.
