The January 2026 update has been released for the Galaxy A55 and Galaxy A34. This isn’t a UI overhaul or a feature addition, though. These phones are actually grabbing the new year’s first security patch that has been said to fix up to 55 vulnerabilities in the current firmware.
We’ll start at the usual place, which is the firmware code. This January patch will bring the Galaxy A55’s One UI 8 build to version A556SKSS6CYL2. The Galaxy A34 is supposed to have the firmware code A346NKSSCEYL2. These were both seen on Samsung’s community posts, by the way.
You won’t see this update in the global market yet, because only South Korea has been receiving the patch for Samsung's latest 5G mobile. It will probably take a few days for Samsung to deploy this OTA to other regions, and hopefully, Pakistan will join the cycle in the coming weeks.
Anyway, about the 55 fixes we mentioned. We are told that 23 of them are from Google on the core Android 16 OS within these devices. And there are at least 4 of them that the Samsung Semiconductor division has deployed with this new January patch.
The major portion, or the remaining vulnerabilities, are getting fixed by Samsung itself. Apparently, of all the patches deployed, 28 of them are high risk, so you’d better update your A34 and A55 as soon as you see the January 2025 patch in the Software Update settings.
Well, the update method hasn’t changed, and it’s as easy as always. All you have to do is open the Settings app. Then you scroll down to the Software Update menu and open it. “Check for Update,” so it can link with Samsung servers to find the January patch.
Then you press Download & Install when you see the changelog and the firmware versions we gave you. By the way, both Galaxy A34 and A55 are eligible for the Samsung One UI 8.5 skin and feature overhaul, so you have plenty to look forward to.
