Samsung Galaxy S10 family receives new updates with August 2020 security patches
Besides Google’s generic Android Security Bulletin (ASB), several major OEMs like Samsung maintain their own version of security bulletins. If you take a look at the Android section of Samsung’s Mobile Security portal, you can get a clear idea about all the disclosed security vulnerabilities affecting closed-source vendor components, the underlying Linux kernel in Android, and various OS frameworks that have been fixed by Samsung till date. At the time of writing this article, the latest monthly security patch level (SPL) is still listed as July 2020 on Samsung’s bulletin, but the OEM has already started rolling out the August 2020 security patches to the Galaxy S10 series in some regions.
The version number of the new build is G97xFXXU8CTG4, and it is currently available for the international variant of the Galaxy S10 (model number SM-G973F) and Galaxy S10+ (model number SM-G975F), both powered by the in-house Exynos 9820 SoC. Interestingly, we can’t find a similar build for the Galaxy S10e (model number SM-G970F) as of now, but it should be made available very soon. The OTA update is available in the DBT region, which is Samsung’s code for Germany. The full changelog for the update is not available yet, but we do know that Samsung ships a new bootloader (v8) with this build. As a result, the end-users can’t perform a downgrade to older builds once they install this update.
Samsung is known for pushing out updates in batches. Even if you are in Germany, you might have to wait a couple of days before the OTA notification pops up on your device. If you’re comfortable with manual flashing, then you can use a community developed tool named Frija to download the updated firmware from Samsung’s repository. The required parameters can be found in the screenshot below:
The decrypted firmware package created by Frija can be flashed using Odin on any regional Exynos Galaxy S10 model, not just the German one. Note that the U.S. and Canadian Snapdragon 855-powered variants of the Galaxy S10 are not compatible with the aforementioned update.
