Reddit user SuperRam56 and X user Padilla report that their Galaxy S25 series devices have received the One UI 8 update in the US.
Some Reddit comments, specifically for those on Verizon and using the phone unlocked, mention that they don’t have the update yet, but it could just be a gradual rollout. Users in many other regions, like Canada, India, and the UK, report that they have received the update, so it’s definitely a wider, global rollout.
The stable One UI 8 update is 3.9GB in size, has a version number ending in BYI3, and comes with the September 2025 security patch level. The changelog highlights features like automatic call captioning and Now Brief functionality. You can check out all the changes this update brings over One UI 7 in our One UI 8 hands-on.
