The new version of Samsung's custom interface, One UI 9 based on Android 17, is experiencing a very active rollout . After debuting on the Galaxy S26 series, the company has decided to accelerate the pace and bring the beta phase to a host of older generation devices. Galaxy S24 and S25 users can already try it, and they're not the only ones.
Samsung's move demonstrates their desire to thoroughly polish the software before the stable release. Meanwhile, those who install the beta will find a host of changes, from improved DeX integration to new security tools. Let's review everything we know so far and how you can get it if you live in Spain or Europe.
The One UI 9 beta arrives on the Galaxy S24 and S25
According to reports, the update is already available for the Galaxy S24, S24+, and S24 Ultra in markets such as the United States, India, and South Korea. Shortly after, the Galaxy S25 series (including the S25 FE) joined the update in the United Kingdom, Korea, and India. The download size is around 3,6 GB , so a good Wi-Fi connection and sufficient free space on your phone are recommended.
What's interesting is that Samsung hasn't stopped there. The beta has also reached other devices like the Galaxy A57 5G in India, and the rollout is expected to expand to more countries, including Spain, in the coming weeks. However, patience is required, as regional availability is limited and not all users will see the update at the same time.
How to sign up for the beta from Samsung Members
The process for trying One UI 9 is quite simple, although it does require keeping an eye on the official app . First, open Samsung Members and look for the banner dedicated to the beta. If your device is compatible and you're in a supported region, the option to enroll in the program will appear.
Once registered, simply go to Settings > Software update > Download and install. Your phone will search for the beta version , and you can install it like any other update. Keep in mind that, as it's a test version, it's normal for some apps to lag or for battery life to be slightly faster than usual.
Key new features in One UI 9
One of the most striking new features is the enhanced integration with Samsung DeX. Now, when you open the recent apps screen, a preview of the home screen will appear at the top, making it easier to switch between apps and tasks. The quick settings panel has also been redesigned, making it more customizable and allowing independent controls for brightness and volume.
Security also receives a significant boost. The Scam Detection feature, already available on Pixel phones, will be coming to more Galaxy devices with One UI 9. This tool uses AI to detect scam call patterns and alerts the user in real time. Additionally, a new app called Warranty & Care has been leaked , which will centralize technical support, repair history, and hardware self-diagnostics, complementing Samsung's photo editing tools and other system utilities.
Which devices will be able to update?
The list of phones compatible with One UI 9 is quite extensive. In addition to the Galaxy S26, S25, and S24, foldable phones like the Galaxy Z Fold 6, Z Flip 6, Z Fold 7, and Z Flip 7 are also included. The mid-range is also supported , with models such as the Galaxy A57, A56, A55, and A36, and even tablets like the Galaxy Tab S10 and S9.
Samsung has confirmed that the stable version will arrive in the coming months , so those who don't want to risk using the beta can wait a little longer. Meanwhile, the company continues to refine details and expand the number of devices that can test the new version of its operating system.
With this expansion, Samsung demonstrates that One UI 9 is a priority . The beta is already available in several international markets and is expected to arrive in Spain soon. If you have a Galaxy S24, S25, or similar device, it's worth keeping an eye on Samsung Members so you don't miss the notification. The improvements to DeX, security, and the new support center make the wait worthwhile.
