Samsung Galaxy S25 series of smartphones are expected to be the first devices to get the One UI 8 update, which is based on Android 16. The company is currently testing the Android 16-based One UI 8 beta on many devices, and has yet to roll out the stable version to any of its devices. While Samsung hasn't officially disclosed the release timeline of the new software, a new leak suggests when users can expect the update. The update could also reach select tablets such as the Galaxy Tab S10+, Tab S10 Ultra, and a few Galaxy Watch 6 series models soon. Samsung's latest foldable smartphones, Galaxy S25 FE and Galaxy Tab S11 series, already ship with One UI 8 out of the box.
Tipster Alfatürk on X shared the alleged roadmap for the rollout of One UI 8 based on Android 16. Samsung is said to start the rollout with the Galaxy S25 series, including the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra, on September 18. Meanwhile, the Samsung Galaxy S25 Edge is tipped to get the update starting September 25
