The Samsung Galaxy S24 lineup has started receiving the One UI 8.5 update in China, according to user reports shared today. The rollout appears to cover the domestic Galaxy S24 family first, bringing a major package that weighs in at roughly 4GB.
The reported firmware build numbers are S9280ZCU5DZDP / S9280CHC5DZDP / S9280ZCU5DZDP, and the update carries a security patch level dated February 5, 2026. While Samsung has not listed every change in the source report, the update is described as introducing a refreshed interface design along with deeper integration of Galaxy AI features.
For a sense of what to expect, the source notes that users can look at features already pushed to the Galaxy S25 series. That suggests One UI 8.5 is not just a maintenance release. Instead, it appears to be part of Samsung’s broader software refresh across its recent flagship devices, combining visual polish with AI-focused additions.
Samsung is also expected to prioritize the new software for a wider group of premium devices. The list mentioned in the report includes the Galaxy S25, S25+, S25 Ultra, S25 Edge, and S25 FE; the Galaxy Z Fold 7, Flip 7, and Flip 7 FE; the Galaxy Z TriFold; the Samsung Galaxy S24, S24+, S24 Ultra, and S24 FE; the Galaxy Z Fold 6 and Flip 6; and the Galaxy Tab S11 / S11 Ultra as well as Tab S10+ / Tab S10 Ultra.
According to the same information, the first wave of eligible models is expected to receive the full One UI 8.5 experience, including system performance improvements, visual refinements, and the latest AI feature bundle introduced alongside the Galaxy S26 family. Some older models may miss a few advanced features, but the core software experience is still expected to remain intact.
