Samsung's One UI 8.5 Stable Update Nears Wide Rollout Across S25, Z Series

Samsung’s stable One UI 8.5 update is close to a wider rollout after extensive beta testing on the Galaxy S25 lineup; a stable build surfaced on Samsung servers, suggesting S25/S25+/S25 Ultra could begin receiving the update within days, with older S, Tab S, and Z devices following in the coming weeks. The plan also targets the Galaxy S24 series and foldables like Z Flip 7/Z Fold 7, while mid‑range Galaxy A/F/M models are expected to get 8.5 in Q2 2026 and entry‑level devices later in 2026.
