The Samsung October 2026 security patch has started reaching the Galaxy S24, S24+ and S24 Ultra. It’s a security-only update with 62 fixes and no new features, so it’s worth installing but won’t change how your phone looks.
Quick Facts
- Reported on October 23, 2026, for the Galaxy S24 family
- Rollout began in South Korea, with other markets to follow over days or weeks
- 62 fixes in total: 45 from Google and 17 from Samsung
- No new features, only security fixes
- Manual check: Settings > Software update > Check for updates
Samsung’s newest phones got the same monthly patch earlier in October, so the S24 is a few weeks behind. That’s normal for older flagships.
What’s inside the Samsung October 2026 security patch?
According to Android Headlines, the patch carries 62 fixes. Google’s share is 45, and the severity split matters more than the total.
| Source | Fixes | Severity breakdown |
|---|---|---|
| Google (Android) | 45 | 9 critical, 33 high, 3 moderate |
| Samsung | 17 | 6 high, 7 moderate (the report doesn’t account for the remaining 4) |
Critical and high-severity bugs are the ones attackers care about. Fixes of that kind usually close holes that could let malicious code run on a phone.
Samsung’s own notes are sparse, and some items can’t be disclosed until later. That’s standard practice, so don’t read it as a red flag.
Who gets it first, and when will your phone see it?
Samsung ships these patches in stages. The newer Galaxy S26 and foldable models received the October release first, as eSecurity Planet reported on October 6.
| Phones | First reported | Where it started |
|---|---|---|
| Galaxy S26 series and newer foldables | Early October 2026 | South Korea, then the U.S. and Canada for the S26 |
| Galaxy S24, S24+, S24 Ultra | October 23, 2026 | South Korea, wider rollout expected |
Expect a wait of a week or two before it reaches your specific phone. Carrier-locked models often arrive later than unlocked ones.
The same patch applies across Android 14 to Android 17, according to eSecurity Planet. That means it’s useful even if you haven’t moved to the latest One UI version.
Which bugs does this Android security update close?
Samsung hasn’t published full details, but eSecurity Planet points to a few examples from the broader October release. They show the kind of risk these updates remove.
One is a high-severity out-of-bounds write in a media extractor library. A local attacker could use it to run arbitrary code. Another is a use-after-free flaw in a Samsung service that could, in theory, lead to system-level code execution.
The release also touches image processing, text-to-speech software, the lock settings component and access controls. None of these is something you’d notice day to day, which is exactly why they’re easy to ignore.
Keep in mind that eSecurity Planet describes the broader October release, not the S24 build specifically. The two lists overlap, but Samsung’s S24 notes may differ slightly.
How to install the update on your Galaxy S24
You don’t have to wait for a notification. Checking by hand takes about a minute.
- Open Settings and tap Software update.
- Tap Download and install (or Check for updates).
- Connect to Wi-Fi and plug in your charger if the battery is low.
- Restart when prompted.
If nothing shows up, that just means your region hasn’t been reached yet. Check again in a few days rather than trying workarounds.
If you’re also thinking about the bigger One UI jump, our guide on One UI 9 battery drain on Galaxy S24 and S25 phones explains what some owners are seeing after updating. It’s worth reading before you upgrade.
Should you worry about not getting it right away?
For most people, no. A bug fixed in the patch is only useful to an attacker if they can reach your phone, and the usual routes are bad apps, malicious links and unknown files.
Until the update lands, stick to Google Play and the Galaxy Store, and don’t open links from strangers. Also keep Google Play system updates current, since they patch some issues separately. We covered the latest one in our Google Play System Update October 2026 post.
Business users with fleets of Galaxy phones should check patch levels on every device. eSecurity Planet recommends this for companies, and it’s easy to do from Settings > About phone > Software information.
