Samsung Tests One UI 9.5 on Galaxy S25 Devices

Samsung is reportedly testing the upcoming One UI 9.5 software on the Galaxy S25 series in addition to the Galaxy S26.

New internal server test builds indicate that Samsung is preparing One UI 9.5 firmware for the Galaxy S25 series alongside the Galaxy S26. While an official beta program has not yet begun, recent sightings of multiple test builds suggest that users may see a beta release following initial testing phases. This early development points to upcoming software enhancements, including potential redesigns for the Samsung Calendar, updates to the Phone app, and additional Bixby features. The stable release of One UI 9.5 is broadly anticipated alongside the launch of the Galaxy S27 line in early 2027.
