Samsung shares official One UI 8 stable update rollout schedule

Earlier this month, we came across a leaked stable One UI 8 rollout schedule for Samsung’s Galaxy devices, and a couple of days ago, Samsung released the stable One UI 8 update for the Galaxy S25 series while sharing a list of devices eligible for the update. The brand initially said these devices would get the update “later this year,” but a post on Samsung Korea’s community then revealed which devices would receive One UI 8 stable in October and November. You can check the screenshot below for those details.
