Samsung has released the October 2023 security update to the global versions of Galaxy S23 series smartphones. The update is currently available in Europe and India, but we expect it to be released all over the world within the next few days. Samsung has already released the new security update for some other high-end phones, including the Galaxy S22.
The new security update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra comes with firmware version S911BXXS3AWIF. It is currently available across Europe, and if it isn't available in a European country where you live, you may need to wait for a couple of days before it hits your device. In India, the new update comes with firmware version S918BXXS3AWIG. The new update is quite small, clocking in at just 350MB (380MB in India), and only includes the October 2023 security patch that fixes dozens of security vulnerabilities found in the previous version of the software.
If you live in Europe or India and have a Galaxy S23 series phone, you can now check for the new update. To do that, navigate to Settings » Software update and tap Download and install. You can also download the new firmware file from our firmware database and flash it manually.
Samsung launched the Galaxy S23 series with Android 13-based One UI 5.1.1 onboard. The company has already released the Android 14-based One UI 6.0 beta update in some countries for testing, and the stable update is expected to go live within the next few weeks.
