The build arrives as G960UOYN3CSAB for the Galaxy S9 and G965UOYN3CSAB for the S9+. It weighs in at around 2GB, so make sure you have plenty of space on your phone for that big of a file and plenty of battery for such a large update.
To check for it, head into Settings>System update.
- UPDATE: AT&T Galaxy S9 phones are receiving the update as well.
