Samsung Expands One UI 9 Beta to More Galaxy Phones


Samsung is opening the doors to its One UI 9 beta program for more Galaxy smartphones, giving owners of several 2025 flagship devices a chance to test the Android 17-based software ahead of its wider release.

The beta first became available on the Galaxy S26 series in May, while One UI 9 already ships with Samsung's latest Galaxy Z Fold 8 and Galaxy Z Flip 8 models. The expansion to older flagship devices is a sign that Samsung is gradually moving the software toward a broader release.

Which Galaxy Phones Are Getting the One UI 9 Beta?

Samsung has confirmed that the One UI 9 beta is expanding to several devices from its 2025 flagship lineup. Eligible models include:

  • Galaxy S25

  • Galaxy S25+

  • Galaxy S25 Ultra

  • Galaxy S25 FE

  • Galaxy Z Fold 7

  • Galaxy Z Flip 7

The beta program will initially be available in India, South Korea, the United States, and the United Kingdom. Users in these markets can opt in through the Samsung Members app when the beta becomes available for their device.

Samsung has not provided a specific day for the September expansion, so owners will need to keep an eye on the Samsung Members app for the registration option.

One UI 9 Is Based on Android 17

One UI 9 is Samsung's software layer built on Android 17. While the Galaxy S26 series has already given users an early opportunity to test the update, the September expansion brings the beta to a much larger group of Galaxy owners.

The move is particularly useful for Samsung because feedback from a wider range of devices can help identify issues before the stable version reaches more users. For beta participants, meanwhile, it offers an early look at what Samsung is preparing for its broader Galaxy ecosystem.

Still, beta software is not intended to provide the same level of stability as a finished release. Anyone considering the installation should prepare their phone before opting in.

Back Up Your Galaxy Phone Before Installing the Beta

A software beta can introduce bugs or unexpected problems, so creating a backup should be one of the first steps before installing One UI 9. Important photos, contacts, documents, messages, and other personal information should be protected before making the switch.

If you are also moving to another device, this is a good time to decide how you want to transfer my data. Samsung's own tools can help with device migration, while other transfer solutions can provide additional options depending on the phones involved.

Smart Transfer can also help users prepare their content before making a major device change. A quick copy my data process can be useful when you want to preserve important information before experimenting with new software or moving content to another phone.

Before installing a beta, it also makes sense to clean up unnecessary files. A free phone cleaner for iPhone can help iPhone users manage storage when preparing their own devices, while Galaxy owners should use the storage-management tools available on their phones to remove unnecessary downloads, duplicate files, and apps they no longer use.

When Will One UI 9 Reach More Galaxy Phones?

Samsung has only confirmed that the beta expansion will begin in September, so there is no official date yet for every eligible device or market. However, expanding the beta beyond the Galaxy S26 series suggests that development is progressing toward a broader rollout.

For now, Galaxy S25 and Z Fold 7 and Z Flip 7 owners in supported countries can watch the Samsung Members app for their opportunity to join the beta. Those who prefer stability may want to wait for the final release instead.

Samsung's wider One UI 9 rollout is still ahead, but this latest expansion brings Android 17 testing to a much larger portion of its Galaxy lineup. If the beta phase proceeds smoothly, the stable update should not be too far behind.
