Samsung has barely scratched the surface with One UI 9, yet the pace of development is already picking up.

At the time of writing, the Galaxy S26 series remains the only lineup officially participating in Samsung’s public One UI 9 Beta Program. That will change over the coming weeks as Samsung expands development to more eligible Galaxy devices. Behind the scenes, Samsung has quietly started testing Android 17-based firmware for a growing number of Galaxy phones and tablets.

Samsung’s internal test builds have historically been one of the strongest indicators that a device is next in line for a major software update. So, whenever Samsung starts testing One UI 9 on a new Galaxy device, launches a public beta, or begins rolling out the stable update, you’ll find the latest development here first.

July 1, 2026: Galaxy A25 5G joins Samsung’s growing One UI 9 testing list

Samsung has started internally testing Android 17-based One UI 9 for the Galaxy A25 5G, making it the latest Galaxy smartphone to join the growing list of devices already running early firmware.

The first known test build carries firmware version A256BXXUCFZF1. While this doesn’t necessarily mean the Galaxy A25 will receive a public beta program, it does confirm that Samsung has officially begun development for the device ahead of the stable rollout expected later this year.

Like many other Galaxy A-series phones, the Galaxy A25 is expected to skip the public beta phase altogether and receive the stable One UI 9 update once Samsung completes internal testing.

One UI 9 device tracker

The table below tracks every Samsung Galaxy phone and tablet that has been spotted testing One UI 9 internally, joined the public beta program, or started receiving the stable Android 17 update.

Which Galaxy phones are expected to receive One UI 9?

Samsung hasn’t published the official rollout schedule yet. However, based on Samsung’s update policy and internal testing, these categories are expected to receive One UI 9 later this year:

• Galaxy S Series
• Galaxy Z Fold Series
• Galaxy Z Flip Series
• Galaxy Tab S tablets
• Galaxy A Series (selected models)
• Galaxy M Series (selected models)
• Galaxy F Series (selected markets)
• Galaxy XCover devices

Not every eligible device will receive a beta program. In fact, Samsung traditionally limits beta testing to flagship models and a handful of premium devices. Most Galaxy A-series phones, tablets and entry-level devices will simply receive the stable update when it’s ready.

When will Samsung release the stable One UI 9 update?

Samsung is expected to publicly debut the stable version of One UI 9 alongside the Galaxy Z Fold 8 and Galaxy Z Flip 8 before gradually expanding the rollout to older eligible Galaxy phones and tablets. Once that happens, the rollout will likely follow Samsung’s usual order:

1. Galaxy S26 Series
2. Galaxy S25 Series
3. Galaxy Z Fold 7 & Galaxy Z Flip 7
4. Galaxy S24 Series
5. Older flagship Galaxy S devices
6. Galaxy tablets
7. Galaxy A Series
8. Entry-level Galaxy devices

Samsung usually prioritizes flagship devices before gradually expanding the rollout to mid-range and budget phones over the following months.

What’s new in One UI 9?

Unlike One UI 8.5, which introduced many visible design changes, One UI 9 focuses more on refinement than reinvention. Some of the changes discovered so far include:

• Android 17 under the hood
• Faster animations and smoother performance
• More Quick Panel customization
• Improved Samsung DeX
• New Samsung Notes pen and tape styles
• Enhanced Game Booster
• More colorful media player widget
• Better background blur and glass effects
• Location privacy indicator
• Additional accessibility improvements
• Stronger app protection and network blocking

Google has also introduced several Android 17 improvements aimed at making devices feel faster while improving multitasking and cross-device experiences.

We’ll keep this tracker updated

Samsung adds new One UI test firmware to its servers almost every week during the early stages of development, and we’ll continue updating this page as new information emerges.
