To join the Samsung One UI beta program, open the Samsung Members app on an eligible Galaxy phone, tap the One UI Beta Program banner or notice, and register with your Samsung account. Once you’re accepted, go to Settings > Software update > Download and install to get the beta. It’s only open in select countries.
When this post first went up in 2018, the beta was for One UI 1.0 on the Galaxy S9 and S9+. Samsung has run a beta for every big One UI release since then, and the sign-up still happens in Samsung Members, so I’ve rewritten the guide for the current One UI 9 beta.
Key points
- Every One UI beta sign-up happens in the Samsung Members app.
- One UI 9 beta started on the Galaxy S26 series in May 2026.
- In September 2026, it expanded to the Galaxy S25 series, Z Fold7 and Z Flip7.
- Only select countries get the beta, and spots can fill up.
- Going back to stable One UI usually wipes your phone, so back up first.
Which Galaxy phones can join the One UI 9 beta?
The Galaxy S26 series got it first, then the S25 series and the 2025 foldables. Samsung announced the One UI 9 beta for the Galaxy S26 series on May 12, 2026, and expanded it to more devices on September 1, 2026.
| Round | Devices | Countries |
|---|---|---|
| May 2026 | Galaxy S26, S26+, S26 Ultra | Germany, India, Korea, Poland, UK, US |
| September 2026 | Galaxy S25, S25+, S25 Ultra, S25 FE, Z Fold7, Z Flip7 | India, Korea, UK, US |
Samsung says timing can differ by market, so check the Samsung Members app on your own phone. Carrier-locked models in the US are often left out.
How do I sign up for the Samsung One UI beta?
Use the Samsung Members app. It comes preinstalled on most Galaxy phones.
- Update Samsung Members from the Galaxy Store or Play Store.
- Open the app and sign in with your Samsung account.
- Look for the One UI Beta Program banner on the home screen, or check Notices.
- Tap it, read the terms and tap Enroll or Register.
- Wait for the confirmation. It can come right away or take a few hours.
- Go to Settings > Software update > Download and install.
- Download the beta and let the phone restart.
If you don’t see the banner, your phone, country or carrier isn’t part of the current round, or the slots are already full.
What should I do before installing a One UI beta?
Back up your phone. Betas can have bugs, and some banking or work apps may not run on them. Use Samsung Cloud, Google One or Smart Switch to save your data, and keep your phone charged above 50 percent before the download.
How do I leave the One UI beta?
Withdraw in Samsung Members, then flash the stable firmware or wait for the stable update. Leaving the program doesn’t roll your phone back on its own. Going back to an older stable version means flashing it with Odin, which wipes your data. If you stay in the beta until the stable release, you usually get it as a normal update without a wipe.
Frequently asked questions
Is the One UI beta free?
Yes. It costs nothing, and you only need a Samsung account and an eligible phone.
Why is the beta banner missing in Samsung Members?
The beta is limited by country, model and sometimes carrier. If it isn’t on your phone, it hasn’t opened for your device yet, or the slots ran out.
Will the beta void my warranty?
No. It’s official Samsung software sent over the air, so it doesn’t trip Knox or affect your warranty.
Can I join the beta on an older Galaxy phone?
Usually not. Samsung keeps betas to its newest flagships and foldables. Older phones get the stable update later, if they’re on the update list.

That’s it. Keep an eye on Samsung Members, since the banner usually shows up a few days after Samsung announces a new round.
If the beta isn’t showing on your phone, leave a comment with your model number and country, and I’ll tell you if it’s open for you yet.
