How to Enroll in the Beta Program

If you are eager to test the latest features before the general public, you must manually enroll your device. To begin, ensure you have the Samsung Members app installed on your phone. Log in with the same Samsung Account used for your device setup. Look for the "One UI 8.5 Beta Program" registration banner within the app's home screen or notices section.

Once your registration is confirmed, navigate to Settings > Software update and select Download and install. Once the 4GB file is fully downloaded, tap Install now. Your Galaxy Z Flip 7 will restart and begin the installation process, which typically takes a few minutes to complete.
