- Wide-Ranging October Patch Rollout: Samsung is rolling out the October 2025 Android security patch to a broad range of Galaxy devices – from its latest Galaxy Z Fold 7 and Z Flip 7 foldables to flagship Galaxy S25/S24 series and even older models [1] [2].
- Dozens of Vulnerabilities Fixed: The update addresses dozens of security flaws. For example, Samsung’s new foldables have 34 vulnerabilities patched (14 high-severity Android OS issues + 20 Samsung-specific fixes) [3]. The Galaxy S24’s update similarly tackles 14 high-severity Android bugs and 12 Samsung-specific issues [4], while the Galaxy S20 FE’s patch fixes 30+ vulnerabilities [5].
- Latest Flagships Got It First: The Galaxy S25 series received the October patch earlier in the month, since those phones already upgraded to Android 16 (One UI 8) back in September [6]. All four S25 models (Standard, Plus, Ultra, and the new Edge) got the update, which “simply bring in security patches” with nothing else new [7].
- Foldables Finally Updated After Delay: Owners of the Galaxy Z Fold 7 and Z Flip 7 are “finally” seeing the crucial October patch a bit later in the month [8]. The foldable update began in South Korea around Oct. 23 and is expected to expand globally in coming days [9]. Samsung advises foldable users to install it as soon as possible given the high-severity fixes [10].
- Older Models Not Forgotten: Even older Galaxy devices that won’t get new OS upgrades are still receiving security patches. The 2020-era Galaxy S20 FE 5G just got the October 2025 patch focused on “improving security and stability” [11], and the budget Galaxy A05 (4G) is getting a belated September patch in some regions [12]. These models aren’t eligible for One UI 8 (the S20 FE is on Android 13, One UI 5; the A05 ended on One UI 7), but Samsung plans a few more security updates for them before support ends [13].
Foldables Get Crucial Patch After Brief Wait
Samsung’s latest foldable phones – the Galaxy Z Fold 7 and Galaxy Z Flip 7 – are now receiving the October 2025 security patch, after a slight delay in the rollout [14]. The update first hit users in South Korea and should reach other regions shortly [15]. This One UI 8-based patch is “behind schedule, but brings a slew of high-level security updates”, addressing 34 vulnerabilities in total [16]. That includes 14 high-severity issues from Google’s Android bulletin and 20 Samsung-specific flaws, some of which are so sensitive that details aren’t being disclosed publicly yet [17]. In other words, this is a crucial update for Fold 7/Flip 7 owners’ security, and experts recommend installing it promptly. Samsung’s Brady Snyder at Android Central even urges foldable users to apply the patch “as soon as possible” given the importance of the fixes [18].
Galaxy S25 Series Got Early October Update
The Galaxy S25 series (Samsung’s 2024 flagship lineup) actually got its October security update earlier in the month, ahead of many other models. Why the head start? The S25 lineup had already been updated to Android 16 (One UI 8) in September, so October didn’t bring any major new OS changes for these devices [19]. As Droid Life’s Kellen wryly noted, the S25 has “basically been chillin’ as its friends catch up” this month after getting One UI 8 early [20]. Now Samsung pushed out a late-October patch for all four Galaxy S25 variants (Standard, Plus, Ultra, and the new S25 Edge), but it’s a pure security update with no extra features. In fact, a Verizon bulletin confirms the S25’s new build simply includes “the most up to date Android security patches” and nothing else [21]. So while there aren’t flashy additions like camera upgrades or apps, S25 owners should still install the patch to get the latest protections. (To check for the update on a Galaxy S25, you can go to Settings > Software update > Download and install [22].)
Galaxy S24 Series Receives First Post-Upgrade Patch
Samsung has also begun rolling out the October 2025 patch to the Galaxy S24 series – including the S24, S24+ and S24 Ultra (and even the S24 FE model) [23]. Notably, this is the first update for the 2024 S24 flagships since they were upgraded to One UI 8.0 (Android 16) [24]. The rollout started in South Korea and should expand globally in the coming days [25] [26]. No new features are part of this release – it’s purely a security maintenance update [27]. But it’s an important one: the October 2025 patch fixes 14 high-severity Android OS vulnerabilities and 12 Samsung-specific security issues on the S24 lineup [28].
It’s worth mentioning that Samsung temporarily paused the One UI 8.0 update for the Galaxy S24 shortly after its release (reportedly pulling the firmware from servers) [29]. That pause was likely due to some early bugs, though most S24 users had already upgraded by then [30]. In any case, Samsung is now moving forward with this routine security patch for the S24 family to keep phones safe. Once the update is available in your region, your Galaxy S24 should notify you automatically. (You can also check manually via Settings > Software update > Download and install.)
Security Updates Extend to Older Galaxy Models
Samsung isn’t just focusing on its newest devices – the October 2025 security patch is also reaching older models in its Galaxy lineup. For instance, the popular Galaxy S20 FE 5G (launched in 2020) has now received the October 2025 update as well [31]. Users in Samsung’s home market of Korea report the new firmware (version G781NKSSDGYJ1) is out, bringing only under-the-hood improvements: it “mainly focuses on improving security and stability rather than adding new features”, with this month’s release containing fixes for 30+ vulnerabilities on the S20 FE [32]. In short, even though the S20 FE is several years old and no longer getting full OS upgrades, Samsung is still delivering vital security patches to it.
Likewise, the entry-level Galaxy A05 (4G) is getting attention – albeit running a bit behind. Samsung has begun pushing the September 2025 security patch to the Galaxy A05 in various Asian markets (including Iraq, Saudi Arabia, Egypt, and Pakistan) [33]. The A05’s new firmware (A055FXXSBDYJ2) doesn’t add anything flashy, but it boosts security for that budget handset. More regions are expected to receive the A05’s update soon [34].
It’s important to note that neither the Galaxy S20 FE nor the A05 will receive Android 16 / One UI 8 – they’ve reached their final major OS versions (the S20 FE is on Android 13-based One UI 5, and the A05’s last big update was One UI 7) [35]. Still, Samsung plans to keep issuing periodic security patches for these devices for a while longer. “They should receive a few more security patches before official support ends,” SammyGuru reports [36]. This continued support helps ensure that even older Galaxy owners aren’t left exposed to new threats.
Why These Updates Matter & How to Update
Samsung’s accelerated rollout of the October 2025 patch across both new and older Galaxy models underscores the company’s commitment to device security. Each monthly patch can include critical fixes that protect phones from malware, breaches, and other vulnerabilities. In this case, the October update addresses a host of high-severity issues – some of which are significant enough that details were withheld until users patch their devices [37]. Staying up to date is therefore crucial: installing these security patches promptly helps keep your personal data and device safe from known exploits.
If you own a Samsung Galaxy device mentioned above (or any recent model), it’s a good practice to check if the October 2025 update is available for you. Your phone will usually notify you automatically once the update hits your region. But you can also manually check by opening the Settings app, navigating to Software update, and tapping “Download and install.” Once the update downloads, follow the prompt to Install now, and your phone will reboot with the latest patch applied [38]. As Samsung continues to push these updates “at full speed across its lineup,” staying on the latest security patch is one of the best ways to ensure your Galaxy device remains protected [39].
