Samsung has kicked off the rollout of its August 2026 security update for the Galaxy A56, A55, and A54, with South Korea getting first dibs as usual. The update was spotted landing on Samsung’s home turf, and other regions should follow within days though Samsung hasn’t published a country-by-country schedule yet.
Don’t expect anything flashy here. This isn’t a One UI feature drop; it’s a straightforward patch. The firmware builds are A566SKSS9CZH9 for the A56, A556SKSSADZH3 for the A55, and A546SKSSJFZH3 for the A54, all tied to the Korean variants in this initial wave.
56 fixes, and a chunk of them are serious
The August 2026 security package Samsung is pushing out addresses 56 vulnerabilities in total 38 tied to Google’s own Android CVEs and 18 specific to Samsung’s software layer. Eight of the Google fixes are rated critical, with another 30 marked high priority. Samsung’s own SVE fixes skew less severe: two high-priority issues and 14 moderate ones, plus two without a disclosed rating.
The patched areas touch a mix of system-level and Samsung-specific components Weaver, Galaxy Themes, Samsung Contacts, clipboard handling, codecs, and cellular radio functions all get mentioned in the bulletin. It’s worth remembering that this list represents Samsung’s full August patch, not a set of bugs unique to these three A-series phones specifically.
One UI 9 is still coming, just not with this update
If you’re expecting Android 17 features to show up alongside this patch, they won’t. One UI 9.0 is a separate rollout that Samsung is still working through it’s currently expanding as a beta to 2025 flagships and foldables, and the A56, A55, and A54 are expected to get their version later. Keep the two updates mentally separate: one is monthly maintenance, the other is a full platform jump.
For owners of these three phones, there’s nothing to do except wait for the notification. Head to Settings → Software update → Check for updates once regional rollout catches up. Given the A56 has been getting monthly patches on a fairly consistent cadence, this is more about routine upkeep than a must-install emergency fix but with eight critical CVEs in the mix, it’s not one to put off once it arrives.
