Samsung is now testing One UI 9 for the Galaxy Z Fold7, A56, S23, and S24 series

Samsung Kicks Off One UI 9 Testing for More Galaxy Devices

If you’ve been keeping an eye on the latest software updates, you know Samsung is moving fast with the rollout of its next big interface iteration. While the Galaxy S26 series is currently front and center with its third One UI 9 beta, the company isn’t sitting idle. New reports confirm that the development team is actively working on bringing One UI 9 to a much wider range of hardware.

Beyond the ongoing tests for the Galaxy S25, the A16, A17, and the upcoming S26 FE, Samsung has officially expanded its testing pool to include some of the most popular devices in its current lineup.

The List Grows: Foldables and Flagships Included

Samsung’s latest push covers a mix of high-end foldables and reliable daily drivers. Specifically, the company is now developing builds for the Galaxy Z Fold7, the Galaxy A56, the Galaxy S23, and the entire Galaxy S24 series.

Here’s a quick breakdown of the firmware activity spotted in the wild:

Galaxy Z Fold7: Internal testing is underway with build F966USQUACZF3.
Galaxy S23: The base model is currently testing build S911BXXUAGZF9.
Galaxy A56: Samsung is working with build A566BXXUBDZFB for this mid-ranger.
Galaxy S24 Series: The S24, S24+, S24 Ultra, and the S24 FE have their respective builds (S921BXXUFEZF7, S926BXXUFEZF7, S928BXXUFEZF7, and S721BXXUCEZF7) currently in the works.

What’s Next for One UI 9?

While it’s still early days, the excitement is building around which device might be next in line for a public beta invite. However, we already know that Samsung is holding back the biggest surprise for its upcoming foldable launch. The Galaxy Z Flip8, Galaxy Z Fold8, and the anticipated Galaxy Z Fold8 Ultra are expected to be the first devices to ship with One UI 9 right out of the box.

If the rumors hold steady, keep your calendar marked for July 22, when Samsung is expected to host an event in London to unveil these next-generation foldables. Until then, expect a steady stream of firmware updates as the company refines the One UI 9 experience for its existing user base.
