Samsung took a new step in the development of its software by starting to distribute the second beta version of One UI 8.5 to owners of the Galaxy S25 line. The update, which arrives with the firmware identification ZYLH, began to be released on December 22, 2025 and is available for the models Galaxy S25, Galaxy S25+ and Galaxy S25 Ultra. Users enrolled in the testing program can check the availability of the new software package directly through the Samsung Members application.
This new phase of the beta program not only moves forward with important fixes, but also expands its geographic reach. The company confirmed that users on Índia and Polônia can now join the program, directly receiving this second build. Para who was already testing the first version, the download is approximately 1.1 GB, while new installations require a larger data package.
The main focus of this update is to improve stability and fix bugs reported by the testing community since the first beta was released. Samsung seeks to refine the user experience before the official release of the stable version, scheduled for early next year, consolidating One UI 8.5 as a robust and reliable operating system.
Improved interface and usability in the quick panel
One of the most noted issues in the first beta was the intermittent launch of quick settings. Usuários reported that, when turning on the device, the quick access panel took a long time to load or displayed visual errors, compromising the agility in using the system’s essential functions.
The second beta addresses this issue directly, ensuring that the dashboard loads consistently and immediately after system startup. Essa correction eliminates a point of frustration and improves the first impression of using the device on a daily basis.
In addition to the functional fix, Samsung made fine adjustments to the quick access menu design. The spacing and positioning of icons have been revised to provide a more cohesive and intuitive visual organization, regardless of the screen resolution used.
These changes aim to create a cleaner and more organized interface, where each element is in its proper place, making it easier to find tools such as Wi-Fi, Bluetooth and airplane mode without the need for additional visual effort.
Smarter media management in the gallery
Organizing photos and videos received special attention in this update. Samsung fixed a critical issue that prevented images organized in group folders from moving correctly to the main page of an album in Galeria. Anteriormente, the photos returned to their original position after reorganization, causing confusion.
With the fix in place, users can now manage their photo libraries with more confidence, knowing that changes made to the album structure will be maintained. Isso is particularly important for those who have large collections of images and rely on organizing them into folders for quick access.
System stability as a top priority
Reliability during everyday use was a central pillar in the development of the Beta 2. The Samsung eliminated a bug that caused a system hang when accessing the “More Views” menu during a phone call. Esse type of unexpected crash compromised one of the smartphone’s most basic functions, and its resolution makes the communication experience more stable and secure.
Additionally, the development team investigated and resolved intermittent issues that led to random device restarts. Esses reboots, reported by several beta testers, could occur in different usage scenarios, from browsing applications to periods of inactivity. The new build promises a more solid system, capable of withstanding long usage sessions without presenting instabilities that interrupt the user’s tasks.
Audio solutions for connectivity and calls
The sound experience has also been improved with specific fixes. One of the most relevant adjustments was the operation of the volume increase button, which in certain conditions did not respond consistently. The update ensures that volume control works predictably in all scenarios.
Another significant improvement is related to audio during calls connected via Bluetooth in vehicles. Usuários reported the generation of unwanted noise or sounds when using the car’s hands-free system, which made communication difficult.
With the new version, the problem has been resolved, providing cleaner calls and more reliable audio. Essa change directly benefits those who use smartphones for work or communication while driving, reducing distractions and improving the quality of conversations.
Camera gets back essential features
The camera application, one of the main attractions of the Galaxy S line, has received significant improvements that go beyond simple corrections. The Beta 2 reintroduced capture modes that were missing from the previous version, such as the popular “Dupla Recording”, which allows you to shoot with both the front and rear cameras simultaneously, and “Única Shooting” (Single Take), which uses artificial intelligence to capture a variety of photos and videos with a single tap. Esses features, now accessible through the Camera Assistant app, offer greater versatility for content creators and casual users. Além of the return of features, professional controls have been refined, providing more precise adjustments to exposure, focus and white balance. The big new feature, however, is the ability to create and share custom camera presets. Isso allows photographers to configure their ideal settings for different scenarios, such as portraits or landscapes, and share these settings with other users, bringing the experience of using dedicated professional cameras closer and creating a community around mobile photography.
Compatibility with third-party applications
To ensure a fluid user experience, Samsung focused on improving the system’s compatibility with third-party applications. The update resolved issues that caused several popular applications to forcefully close during use, a common problem in early phases of software testing.
Stabilization was achieved through adjustments to the operating system and multiple updates to Samsung’s own applications, including the camera, which now interacts better with image editing software and social networks.
The path to stable release
The One UI 8.5 beta program was originally launched on December 8, 2025 in select markets including Coreia, Sul, Alemanha, Reino Unido, and Estados Unidos, and the arrival of
