Samsung is reportedly rolling out its October 2026 security patch to Galaxy S26 users in the U.S. The patch is approximately 530MB and delivers over 60 security fixes for the flagship series. This update arrives shortly after One UI 9 (Android 17) rolled out in the U.S. for S26 users. Tipster Kailash on X reported the update has started arriving globally on the Galaxy S26 series, reaching devices in the U.S. and Canada with a 531MB download.
Users can download version S948U1UES4BZIG for the S26, S948U1OYM4BZIG for the S26 Plus, and S948U1UES4BZIG for the S26 Ultra. Samsung only details security improvements once the update hits a user's device, noting roughly 50 fixes from Google and 13 from Samsung, pushing the total to 62. Many fixes address Android 14 to Android 17 vulnerabilities, targeting arbitrary code execution and unauthorized system privilege access.
There are expectations the patch could arrive for the Galaxy S25 series next week, potentially involving a global release. This monthly security update follows the full release of One UI 9 (Android 17) for the latest flagship series, which was spotted for the S26 Ultra in the U.S., with T-Mobile users among the first to receive the approximately 4GB update in September 2026. Other users with AT&T and Verizon services should have started downloading in mid-to-late September.
