Samsung is expanding the public beta testing program for One UI 9.0, built on the Android 17 operating system, to a significantly wider range of Galaxy smartphones, according to company announcements. Initially launched in May and restricted strictly to the newest flagship line, the testing phase now encompasses older flagship tiers, foldable devices, and a popular mid-range model.
Eligible Galaxy Devices for the One UI 9.0 Beta
Samsung has updated its software roadmap to include various device generations in the One UI 9.0 preview. According to the release details, the beta software is no longer exclusive to the Galaxy S26 lineup. The expanded device roster covers several key hardware families released over recent product cycles.
The verified list of compatible smartphones includes:
- Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra
- Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and Galaxy S25 FE
- Galaxy S24, Galaxy S24+ and Galaxy S24 Ultra
- Galaxy Z Fold 7 and Galaxy Z Flip 7
- Galaxy Z Fold 6 and Galaxy Z Flip 6
- Galaxy A57 5G
How to Register for the Beta Program
Access to the One UI 9.0 testing phase depends heavily on the geographic registration of the user’s device, based on Samsung’s deployment rules. Devices in the Galaxy S26 family have broader availability in regions such as Germany, Poland, the United Kingdom, the United States, India, and South Korea. Other qualified hardware lines face more restricted geographic availability during this initial rollout phase.
Pro Tip: Before initiating any software installation, back up your device data. Beta software frequently includes bugs, unexpected reboots, or stability issues that can disrupt daily tasks, making them unsuitable for primary communication devices.
Eligible users located in a supported region can join the program by opening the Samsung Members application and selecting the dedicated One UI 9.0 beta banner for registration. Once the registration receives validation from the company’s servers, users need to open the device Settings menu, navigate to Software update, and manually download the package.
