Samsung Begins July 2026 Security Patch Rollout to Galaxy S26

Overview

• Samsung has started delivering the July 2026 security patch to the Galaxy S26 series in South Korea using firmware S94xNKSS4AZG3 with a 553.54MB package.
• The update addresses 57 security issues, including fixes credited to Google and Samsung and repairs for several critical and high-severity vulnerabilities.
• This month’s rollout followed an unusual order in which Galaxy Watches received the July patch before smartphones, and the phone update will expand to other regions in stages.
• Users can check for the update manually by going to Settings > Software update > Download and install, though staged distribution means availability may appear later in some markets.
• Samsung is expected to release a stable One UI 9 build tied to new Galaxy Z Fold and Flip models later this month, and that release will likely shape the timing of broader OS upgrades for eligible devices including the S26 series.
