With Samsung bumping the Galaxy S8 and S8+ to Android Oreo, it would be natural to assume the company was done with updates for the immediate future. However, the software teams must be working overtime as yet another update is available for the Samsung Galaxy S8 and S8+. This time around we see some security fixes and, more significantly, stability improvements for the camera, Bluetooth, and WiFi.
Don't Miss: Galaxy S8 vs Galaxy S9: is it worth upgrading?
The build began to roll out in Germany initially with users seeing the 570MB update with the version number showing as G950FXXU1CRD7
for the Samsung Galaxy S8 and S8+, respectively. The size is pretty big, and that's just because the devices didn't launch with Android Oreo out of the box so are not Project Treble compatible. Contained in the security fixes for this update is the April 2018 patch, which is a pretty important one. It closes several critical Android vulnerabilities and around eight fixes applied directly to the Samsung software. The most severe exploit that has been fixed is that involving the Media framework, which could enable a remote attacker to execute arbitrary code as a privileged process. The full list of patched vulnerabilities is available here
and continues to highlight the importance of regular security patches for Android.
Samsung doesn't explicitly detail the stability improvements for the camera, Bluetooth, or WiFi, but if you've been experiencing issues with these particular functions, there is a chance this update may have addressed them.
Typically the updates are released in batches for geographical regions so will gradually become available to more countries as time progresses. If you haven't seen the update notification hit your device just yet, then don't panic. You can always manually force a check of available updates by going into the Software Update
menu, then tap Download Updates Manually
