First software update for the Galaxy S23 series is rolling out widely


A couple of days back, Samsung released the first software update for the Galaxy S23 series. The rollout began in Europe. But the company has wasted no time to bring it to other regions. The update is now available for Galaxy S23 users in Asia and Africa as well, including in Samsung‘s homeland South Korea. We expect the company to release the update in the US over the next few days.

Galaxy S23 units sold in Europe, Asia, and Africa bear the same model number (SM-S911B for the base model, SM-S916B for the Plus, and SM-S918B for the Ultra). So the updated firmware version for the phones in these regions is the same — S91*BXXU1AWBD. But the South Korean versions ship with the model number SM-S91*N. The latest update comes with firmware version S91*NKSU1AWBD in the country.

The story is similar for Galaxy S23 phones in Taiwan, Hong Kong, and China as well. The new Samsung flagships bear the model number SM-S91*0 in these markets. Users are getting the new update with the firmware build number S91*0ZHU1AWBD. But regardless of the firmware version, the latest update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra has the same changelog everywhere.

The February update for the Galaxy S23 reaches more markets

Samsung’s changelog for the first firmware release for the Galaxy S23 series doesn’t go into detail. It only states that the package contains some optimizations and the February 2023 Android security patch. The latest SMR (Security Maintenance Release) patches more than 50 vulnerabilities.

Samsung’s security bulletin says seven of those are Galaxy-specific. Those vulnerabilities don’t exist in Android devices from other brands. They patch flaws in Fingerprint TA, Secure Folder, and other systems apps and services.

The remaining 40-odd vulnerabilities patched by this month’s security update are part of Google’s latest ASB (Android Security Bulletin). They patch flaws in Android OS and other partner components. The Android maker labeled five of those as critical vulnerabilities that could potentially allow remote code execution if a threat actor exploited them in the wild. It could pave the way for them to remotely control your phone.

If you are one of the early buyers of Samsung’s latest flagships, you might want to install this update as soon as possible to stay safe from these vulnerabilities. You can go to the Software update menu in the Settings app and tap on Download and install to check for updates manually or wait for a notification prompting you to download the update. For users in the US, we will let you know when Samsung releases the update stateside.
