Samsung might’ve accidentally given away when One UI 8.5 is landing on older Galaxy phones. However, it’s worth taking this one with a bit of caution.
According to a screenshot shared by tipster @MatthewReiter05 (via @theonecid), a Samsung support agent suggested that the stable One UI 8.5 rollout could begin April 30 in Korea.
There could be a global and US release around May 4. If accurate, that puts the update just a few weeks away for devices like the Samsung Galaxy S25 series.
It lines up, at least loosely, with earlier claims from leaker Tarun Vats, who suggested a similar rollout window. But that’s about as far as the certainty goes.
Support chats aren’t exactly known for breaking reliable launch news, and Samsung hasn’t officially confirmed any dates. These timelines can shift quickly depending on last-minute bugs or regional testing delays, and support agents don’t always have access to final rollout schedules. In other words, this could be informed guesswork rather than a genuine early reveal.
Still, the timing isn’t entirely out of place. Samsung already shipped One UI 8.5 with the newer Galaxy S26 series, and it’s been gradually expanding beta access to older devices, including mid-range phones like the Galaxy A35 and A55, as well as foldables in the Z5 line. That wider testing phase usually signals a stable release isn’t too far off.
For Galaxy S25 users, the update is expected to bring a mix of refinements rather than a full overhaul – building on the existing One UI experience with performance tweaks, UI polish, and incremental feature updates.
So while early May is shaping up as a possible window, it’s not locked in just yet. Until Samsung makes it official, it’s best to treat this as a likely-but-unconfirmed timeline rather than a guaranteed release date.
