Samsung has recently rolled out the July 2023 security update for the carrier-locked versions of the Galaxy Note 20 and Galaxy Note 20 Ultra in the United States. The firmware version N98xUSQS4HWF5 is being released across all major carrier networks gradually over the next few days. This update primarily focuses on enhancing device security by addressing over 90 security vulnerabilities found in the previous software version.
What’s new in this update?
The July 2023 security patch contains a total of 90 fixes, with 52 of them being provided by Google, while the remaining 38 are Samsung’s own fixes (SVEs). Among these, three critical and 56 high-priority security flaws have been addressed. The remaining fixes are considered moderate risks. Notably, Samsung had already included three fixes from the June 2023 patch, which are now also part of the July update released by Google.
The security flaws resolved by Samsung cover various areas, including manual package installation via ADB command, audio system access control, UWB chipset identifier, broadcast SMS configuration, Galaxy Themes Service, Settings access control, and out-of-bounds write issues in internal testing functions. These fixes mitigate the risks of potential unauthorized code execution and bolster overall system security.
If you own a carrier-locked Galaxy Note 20 or Galaxy Note 20 Ultra in the US, you can manually check for the new update by navigating to Settings > Software update and selecting Download and Install.
Galaxy Note 20 series was initially launched with Android 10, the devices received subsequent updates to Android 11, Android 12 in late 2021, and Android 13 in late 2022.
