Samsung has expanded the October 2026 security update for the Galaxy S26 series in the US and Canada. The new update brings the latest security improvements to Galaxy S26 users and helps keep their phones safe from security problems.

For Galaxy S26 users in Canada, the update comes with firmware version S948WVLS4BZIG. In the US, the update is available with firmware version S948U1UES4BZIG. The update is live for unlocked models of the Galaxy S26 series in the US.

The main change in this update is the new October 2026 security patch level. Samsung regularly releases security updates to fix security issues found in Android and its own software. Installing the latest security patch can help protect your phone from possible security threats.

The October update may also include general bug fixes and improvements to the phone’s performance and stability. However, this is mainly a security-focused update, so users should not expect major new features or big changes to the user interface.

The update is around 531.24 MB in size. Users should make sure their phone has enough battery and is connected to a stable Wi-Fi network before downloading and installing the update.

Galaxy S26 users can check for the update by going to Settings >> Software update >> Download and install. If the update is not available yet, users may need to wait a little longer because Samsung usually releases updates in stages.

Samsung brings fresh One UI 9 Beta updates to the Galaxy A16 and Galaxy A55. The former is getting the second Beta update, while the latter is receiving the third Beta. September 2026 security patch is tagged alongside the updates.

The Korean tech giant has already started the official One UI 9 rollout. Eligible devices are gradually receiving the update in different markets. Initially available in Korea, the builds will soon be released in the global market.

Build versions:

• Galaxy A16 5G: A166PXXU9ZZJ1 [Beta 2 | via Kailash]
• Galaxy A55 5G: A556SKSUBZZI9 [Beta 3 | via Tarun]

Galaxy A55 One UI 9 Beta 3 changelog:

• A  key fix for Wi-Fi stability improvements

Samsung has addressed a key issue affecting Wi-Fi stability. That should make wireless connectivity more consistent for beta testers.

Galaxy A16 One UI 9 Beta 2 changelog:

• Fixed an issue where fast charging was not working.
• Fixed an issue where battery protection failed when powered off.
• Fixed a bug in the camera app where the “Quick setting” icon appeared during image capture with a timer.
• Updated the Photo Editor version.

Samsung has resolved an issue that prevented fast charging from working properly, which is arguably the most important fix in this build for everyday users.

The update also addresses a problem where battery protection could fail to work when the phone was powered off. Samsung has also cleaned up the camera experience.

A bug that caused the Quick setting icon to appear while capturing images with the timer has been fixed. In addition, the Photo Editor has been updated to a newer version.

For Galaxy A16 and A56 owners enrolled in the One UI 9 beta program, these builds should therefore be viewed as refinement updates.

Samsung is more widely rolling out its October 2026 update, bringing 79 security improvements to the Galaxy Z Fold 8 and Z Fold 8 Ultra.

Samsung’s latest foldable phones receive new updates every month. This is the best software support offered by the Galaxy maker to its users. The other frequency is Quarterly, guaranteeing a new update every three months.

Meanwhile, SEAMLESS UPDATES tech ensures uninterrupted software updates. You keep using your phone during the extraction and installation process, and just a quick reboot applies the latest OTA to the software system.

Galaxy AI features

Galaxy Z8 foldables debuted with various new Galaxy AI features. The list includes enhanced Now Nudge, My FanCam, upgraded Interpreter, and AI-powered Call Brief function.

Samsung is bringing these advanced features from the latest foldables to existing flagship models. They were accurate in previously released models, reiterating that the optimization has gone well.

Galaxy’s October 2026 security updates are rolling out gradually, and Samsung has now revealed the release roadmap. Whether you own a Galaxy phone, foldable device, or tablet, this is an important monthly check.

Samsung constantly provides its roadmap in two segments: Monthly and Quarterly. Flagship devices receive monthly updates, while others get them quarterly.

Here’s the comparison between the September 2026 and October 2026 lists.

New devices added (3), all in Quarterly, Galaxy A Series

• Galaxy A07s
• Galaxy A08
• Galaxy A18

Devices removed (2), both from Quarterly, Galaxy A Series

• Galaxy A04s
• Galaxy A23 5G

These two are older models, so they have most likely reached the end of their update lifecycle. The schedule itself doesn’t state a reason.

Here’s the latest update frequency schedule released on October 6, 2026.
