Samsung Resumes One UI 8 Rollout for Galaxy S23 with Critical Security Patch

Samsung has restarted its Android 16-based One UI 8 update for the Galaxy S23 series. The rollout was briefly paused earlier this week. The company has now restored the firmware on its servers. Users are receiving a new package that includes the latest security enhancements.

This swift resumption follows a similar pattern with the Galaxy S24 lineup. The move ensures users get the latest features without a significant delay. According to Reuters, such rapid update corrections are becoming more common in the tech industry.

Update Focuses on Security and Stability

The new update is currently available for the Galaxy S23, S23+, and S23 Ultra. The Galaxy S23 FE is expected to receive the same treatment soon. The package primarily delivers the October 2025 security patch.

This patch addresses approximately two dozen vulnerabilities. These flaws affected both the core Android OS and Samsung’s proprietary One UI software. The update aims to close security gaps and improve system stability for all users.

How to Install and What to Expect

To download the update, users should navigate to their phone’s Settings app. Then, select “Software update” and tap “Download and install.” The rollout began in South Korea but will expand to other regions imminently.

The download size is around 400MB for devices already running One UI 8. For those still on the previous One UI 7, the file will be much larger. This larger package contains the full upgrade to the new operating system and interface.

The restoration of the Samsung One UI 8 update delivers enhanced security and the latest Android features to millions of users. This decisive action underscores the company’s commitment to its software support promises. Galaxy S23 owners can now confidently update their devices.
