The Galaxy Watch4 and Galaxy Watch4 Classic are no longer on Samsung’s list of supported wearables. Samsung’s own Security Updates Scope page, which lists every watch currently eligible for updates, runs from the Galaxy Watch5 up through the Galaxy Watch9 — the Watch4 series isn’t there.
According to Gizmochina, the two watches also don’t appear in Samsung’s September 2026 security bulletin, and the patch both models received in August was their last. Samsung’s own page doesn’t publish a bulletin history, so that specific timing comes from Gizmochina’s reporting rather than a Samsung statement.
Samsung Delivered What It Promised
This isn’t a case of Samsung cutting a phone or watch off early. At launch in 2021, Samsung promised the Watch4 series four generations of Wear OS upgrades, and it delivered all four:
- Wear OS 3.5 / One UI Watch 4.5
- Wear OS 4 / One UI 5 Watch
- Wear OS 5 / One UI 6 Watch
- Wear OS 6 / One UI 8 Watch (final)
The Watch4 was Samsung’s first watch built on the unified Wear OS platform it co-developed with Google, and by Gizmochina’s account, it got the full run of updates Samsung committed to at launch. Both watches will keep working normally; they simply won’t receive new features or security patches going forward.
Newer Watches Get a Longer Runway
Samsung’s current watch lineup promises more. The Galaxy Watch9 and Galaxy Watch Ultra 2 now carry a revised policy covering five years of One UI Watch and security updates, a year longer than what the Watch4 series got. Samsung’s own supported-models page also still lists the Galaxy Watch5, Watch6, Watch7, Watch8, and Watch Ultra as current.
If you’re still on a Galaxy Watch4, one small sign of where Samsung’s attention has moved: its own galaxy-watch4 product page on samsung.com now redirects straight to the Galaxy Watch7 buy page.
For anyone shopping for a replacement, the trade-off is straightforward: a newer Galaxy Watch now buys a longer support window than the one the Watch4 series originally had.
