To nobody’s surprise, carrier’s took their own sweet time to release Oreo for the Galaxy S7 and S7 Edge. But, the wait is over now as the update has been rolled out en-masse. AT&T released it first, followed by Verizon (which had its own share of hiccups). Today, Sprint joins that list, leaving only T-Mobile. The update was first spotted two days ago and more users have confirmed that they’ve received since then. The update bumps up the build number to R16NW.G93xPVPU6CRE7 and brings the May security patch with it. Additionally, you get most of the Samsung Experience 9.0 features that the Galaxy S8 and S8+ received with their Android Oreo updates.
