Samsung’s Galaxy S25 and S24 phones on One UI 8 are receiving a new update. The latest release appears to bring stability enhancements, potentially addressing minor bugs contained in the original One UI 8 build. The devices remain on the September 2025 security patch, so no new security fixes here.
Galaxy S25 and S24 phones get first updates after One UI 8
Last month, Samsung officially kicked off the One UI 8 rollout for Galaxy devices. The Galaxy S25 series received the update first, with the S24 lineup following a week later. These phones have now picked up the Android 16-based update in most parts of the world. Meanwhile, Samsung is here with another update for these flagships.
Galaxy S25 users in Korea are getting firmware version BYI9, while Galaxy S24 owners are receiving CYI9. The official changelog hints at system stability and optimizations. This likely means the updates are designed to smooth out lingering issues from the One UI 8 upgrade, ensuring a more reliable and polished experience.
One UI 8 is one of Samsung’s most significant upgrades yet, introducing a cleaner UI, enhanced Galaxy AI features, and smarter refinements across system apps. The first maintenance update after such a major rollout is crucial. These updates typically address bugs, stabilize performance, and fine-tune new features for daily use.
For now, the latest software releases for the Galaxy S25 and S24 lineups are only available in South Korea. However, Samsung should soon expand the rollout to cover more markets. With the October security patch expected shortly, we won’t be surprised if the company bundles these optimizations with the latest security fixes in some regions.
Users can manually check for the update by navigating to Settings > Software update > Download and install. The update is relatively lightweight, meaning it can be downloaded even over a cellular network without worry.
