The latest flagship duo Samsung Galaxy S8 and the S8 Plus are now receiving a firmware update with the latest Android Security update. The firmware build number G955FXXU1AQH3 and G950FXXU1AQH3 comes to the stunning Galaxy S8+ and S8 respectively. The latest Baseband versions bring a new August 2017 Security Patch update from Google’s Android open source project.

Is the new update based on Android 7.1.1 Nougat? No! Unfortunately, the update is not based on the highly anticipated Android 7.1.1 Nougat from Samsung. This is because almost all the features are already present in the Samsung Experience 8.1 Android 7.0 Nougat build. We may expect a direct jump to Samsung’s Android O for its premium devices.

We have already seen similar security update to other Samsung Galaxy devices like Galaxy S7/S7 Edge. The first August Security update was released for Galaxy J7 Prime even before Google officially released it for Pixel and Nexus series phones. Other Galaxy phones shall follow the same fate.

The August security update brings optimization to the Auto brightness control and improved PC connectivity. Not much is listed on the change log for that matter. But it may include core Android stability, bug fixes, and OS optimizations.
