Thank you for your interest in participating in the One UI 9 Beta Program on your Galaxy S26 Ultra.

To join, please follow these steps:

1. Open the Samsung Members app and sign in with your Samsung Account.
2. Look for the One UI 9 Beta Program banner or Beta Card on the Home page and select it.
3. Select “Registration for One UI Beta Program” and complete the registration.
4. Once enrolled, go to Settings > Software update > Download and install to check for the Beta update.

The One UI 9 Beta Program is currently available only in selected markets and for eligible Galaxy S26 series devices. If the Beta banner does not appear in Samsung Members, your device or market may not currently be eligible.

We also recommend backing up your important data before installing Beta software, as Beta versions may contain unexpected issues or cause data loss.
