Samsung has quietly pushed the November 2025 security patch to its flagship tablet line, the Galaxy Tab S11 series. The rollout starts in South Korea and brings a handful of fixes and stability improvements aimed at closing multiple security gaps.
What’s included in the update
The new release installs firmware X730XXS3AYJ3 for the Galaxy Tab S11 and X930XXS3AYJ3 for the Galaxy Tab S11 Ultra. The download is roughly 300MB and primarily delivers the November 2025 security patch, which resolves more than 25 security vulnerabilities discovered in prior firmware.
How to install the patch right now
If you own a Tab S11 or Tab S11 Ultra in South Korea, you can trigger the update manually. Go to Settings > Software update > Download and install. Once the package finishes downloading, choose Install now to complete the process. A restart will likely be required.
Why this matters — and what delayed the release
Samsung’s monthly security cadence slowed recently as the company prioritized the large One UI 8 rollout. That work appears to be wrapping up, so security updates like this one are back on the schedule. Patching over 25 issues helps keep sensitive components of the tablet — from system services to connectivity layers — more secure against emerging threats.
Will the patch reach other regions soon?
The update is currently available in South Korea. Based on Samsung’s usual distribution pattern, we expect regional rollouts to follow over the next few days or weeks. If you don’t see the update immediately, check for it periodically or watch Samsung’s official update tracker for timing in your country.
Quick notes
- Package size: ~300MB.
- Devices: Galaxy Tab S11 and Tab S11 Ultra.
- Fixes: 25+ security vulnerabilities in the November 2025 patch.
- How to check: Settings > Software update > Download and install.
Samsung is also moving other software pieces around — from One UI 8 updates to regional device rollouts — so keep an eye out if you use multiple Samsung devices. Security patches like this one are a routine but important step to keep your tablet running smoothly and safely.
