Samsung began rolling out the June 2026 security patch to Galaxy S25 owners in South Korea, the usual launch market. The update, identified as firmware vS938NKSUACZF1, weighs roughly 800‑900 MB and arrives a month after One UI 8.5 debuted on the flagship. Early reports show the download size and rollout timing matching Samsung’s typical schedule. The patch also patches known exploits.

Beyond bug fixes, the patch introduces two AI‑driven notification tools that were absent from One UI 8.5: Prioritize and Summarize. Prioritize lifts important alerts to the top of the feed, while Summarize condenses messages into bite‑size snippets. A user also noted a third option, “Show file summaries,” which creates AI summaries of PDFs, text files and voice recordings. These additions align with Samsung’s AI roadmap.

Samsung’s monthly bulletin lists five critical and 28 high‑severity fixes, including a patch for a vulnerability affecting Android 15 and 16 devices. By delivering AI features now, the company keeps the S25 competitive against newer S26 models that launched with similar tools. Users in the U.S., Europe and other regions should see the update within days, completing the rollout. It reinforces the brand’s commitment to timely security.
