Samsung has launched the beta in the United States, United Kingdom and South Korea in the first phase. Samsung today released the second firmware update for the Samsung Galaxy S8 and the Galaxy S8 Plus units that are running the beta version of Android 8.0 Oreo.

Included with the software upgrade is the October 2017 Android security patch, which resolves 215 vulnerabilities found in Google’s operating system. The second beta firmware update with version number G950FXXU1ZQK4 is now being rolled out by Samsung, which has a file size of 609MB. It has been rolled out in the United Kingdom already and will also go live in other supported markets soon.

Among the security issues fixed with this update are a number of critical vulnerabilities found in the media framework of the OS and a remote code execution vulnerability. The stability of both the launcher and DeX Mode, a feature that allows the handset to be connected to a monitor and PC peripherals, have been improved.

Interestingly, even though the changelog says that it has the October security patch, the Software Information section mentions the September patch. It just might be a clerical mistake.

There are also new features incorporated into the software upgrade, like the new clock styles for the lock screen and the Always-on Display and options for adjusting the transparency of notifications.

There are also a number of bugs that should be fixed once the software package is installed, including the forced closure of the settings app as well as the freezing and restarting of TouchWiz when icons are moved from the app drawer to the home screen.

The second phase of the rollout will also encompass China, Spain, Germany, India, Poland, and France. Samsung is yet to confirm when the second phase of the beta program will begin.
