Samsung was originally expected to launch the One UI 8.5 beta program in November, but the plan was reportedly delayed due to changes surrounding the Galaxy S26 lineup. With the new test build now live, it appears those delays may finally be behind the company.
One UI 8.5 is set to ship natively with the Galaxy S26 series next year. However, with the beta build, Galaxy S25 owners will be the first to try out the updated software. If Samsung follows its usual pattern, the beta can be expected to launch in South Korea before the end of December, followed by expansion to markets such as the US, Germany, India, and the UK.
