The Samsung Galaxy Watch4 and the Galaxy Watch4 Classic have reached the end of their update journeys. These two launched in August 2021 and were the first Galaxy watches to run Wear OS – previous models like the Watch3 used Tizen.
They came with Wear OS 4 out of the box and were upgraded to version 6.0 – with One UI Watch 8 on top. That is their final Android version, but now they won’t even get security patches.
Here is Samsung’s latest security bulletin – it details which devices are getting security updates and how often (i.e. monthly or quarterly).
As you can see, the Watch4 models are no longer on the list. The closely related Galaxy Watch FE is still there, however. The FE model arrived in 2024 as a re-launch of the 40mm Watch4. There were a few changes, but, crucially, the watch uses the same Exynos W920 chipset that was paired with the same 1.5GB of RAM and 16GB storage configuration. The W920 chip is also used in the Galaxy Watch5 duo, which will continue to receive patches too.
Anyway, the last update that the Galaxy Watch4 saw came in August. This generation had a good run – it was supported for 5 years. Even the latest Galaxy Watch9 and the Watch Ultra2 are set for 5 years of OS and security updates.
