If you’re using the Galaxy S8 on AT&T, then you should receive the update very soon. The update carries the build number G950USQU1AQJC, as seen in the screenshot above. It is still Android 7.0 Nougat, and it installs the October Android Security patch. It’s sized about 165-473MB. depending on your current software version.
The Samsung Experience version is 8.1, and that’s about all we know so far. This is a recommended install, and is more of a security update. Samsung and other US carriers have been releasing similar updates for other devices as well.
