Samsung is providing Galaxy S26 series users with a new software update based on the One UI 9.0 operating system. The devices have already received the October patches earlier this month, and this update was expected to carry November patches.

The company initially started the update rollout in South Korea on October 26. The company has expanded the firmware to Global users in Europe and India as of October 29, with a US expansion planned this week.

Galaxy S26 family’s new BZJA/BZJB update is aimed at enhancing the One UI 9.0 build. The security patch level is unchanged at October 2026. This release weighs up to 700 megabytes, offering stability and reliability improvements.

Here’s everything new in the Galaxy S26 BZJA/BZJB update

Samsung’s second software update released for the Galaxy S26 series in October 2026 focuses on system stability, security hardening, and potentially resolving a setup-screen freezing bug affecting some Galaxy S26 Ultra users.

Although the changelog does not identify specific bugs, this improvement could include a fix for the One UI 9.0 issue that prevents some Galaxy S26 Ultra units from completing the setup process after a factory reset.

Samsung acknowledged the problem after users reported being stuck on a setup screen displaying a webpage-loading error when attempting to sign in to their Samsung Account. The issue was linked to an unstable system WebView component on certain networks.

Given that commitment, the second October release is expected to address the freezing issue. However, Samsung’s published changelog does not explicitly confirm the fix, so its inclusion remains unverified.

Downgrade restrictions: Samsung warns that users cannot roll back to a previous software version with a lower security patch level after installing this update.

You can update your Galaxy’s software through Settings > Software update > Download and install.

Release notes:

Stabilization code applied: Improves device stability related to general operations.

Security code applied: Applies Google and Samsung security fixes for October 2026.

Important notice: Due to enhanced security policies in this update, you cannot downgrade to previous software versions with lower security patches.

App updates: Samsung system apps may be updated to their latest compatible versions after installation.

Samsung is rolling out another round of October 2026 software updates, with the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and potentially the Galaxy Z Flip 8 receiving their second update of the month. Meanwhile, the Galaxy S24 FE is getting an October security update based on One UI 9, while the Galaxy S23 FE remains on One UI 8.5 for now.

The latest update activity highlights Samsung’s continued software maintenance across its newest foldables and older Fan Edition phones.

Getting a second update within the same month is notable, although it does not automatically mean that the devices are receiving major new features. These releases could include additional security fixes, bug patches, stability improvements, or refinements to the existing software experience.

For the Z8 series, the back-to-back October releases suggest Samsung is continuing to fine-tune its latest foldable experience. Users should still check the firmware details and changelog before expecting specific improvements.

The Galaxy S24 FE’s October update is more interesting from a software-version perspective. It arrives on One UI 9, bringing the device onto Samsung’s newer software platform while continuing routine security maintenance.

Samsung is reportedly pushing Galaxy S23 FE’s October update based on One UI 8.5, with the One UI 9.0 upgrade delayed until November. This means owners may have to wait a little longer for the next major software transition.

Software build versions:

• AZJ8: Galaxy Z Fold 8
• AZJ8: Galaxy Z Fold 8 Ultra
• EZJ1: Galaxy S24 FE
• EZJ2: Galaxy S23 FE (One UI 8.5)

Overall, Samsung’s October rollout shows that security maintenance and major One UI upgrades do not always follow the same schedule.

Firmware availability can also vary by region and carrier, so users should check Settings > Software update > Download and install to see whether the latest release is available for their device.
