Samsung has initiated the rollout of the final One UI 9.0 update, starting with the Galaxy S26 series in South Korea. The company's Thai division has now confirmed the release schedule for international markets, following the standard practice of prioritizing the domestic region before expanding availability globally.
According to the official schedule, the update for the Galaxy S26 series in Thailand is set for September 21. A second wave of updates is scheduled for September 28, which will include the Galaxy S25, Galaxy S25 Plus, and Galaxy S25 Ultra. This release window also covers the Galaxy Z Fold 7 and Galaxy Z Flip 7 models.
The rollout for the Galaxy S23 FE is slated for a later date. Samsung plans to release the final version of One UI 9.0 for this specific device in October. The company maintains its established pattern of staggered regional updates, ensuring that international users receive the software shortly after the initial launch in South Korea.
