[Samsung Galaxy S23 Ultra] Idebutterpiep:
Just received the October security update on my unlocked S23U, SM-S918B EUX. over OTA. The new update comes with firmware version S918BXXS3AWIG. The new update is quite small 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 firmware database and flash it manually.
