Shortly after Verizon and T-Mobile updated their Samsung Galaxy S8 and S8+ to Android 8 Oreo, Sprint is now doing the same thing. In fact, at least a few Sprint Galaxy S8 owners received the Android Oreo update yesterday, March 17.
Samsung Experience 9.0 interface (which comes pre-installed on the brand new Galaxy S9 series).
If you haven’t received a notification alerting you about the Oreo update, you can always manually check for it on your Galaxy S8 via Settings -> Software update -> Check for updates.
As things stand now, AT&T remains the last major US carrier to update its Samsung Galaxy S8 phones to Android Oreo, but we hope it’ll do it in the near future.
P.S.: In case you're wondering, the Samsung Galaxy S8 Active - available on Sprint, AT&T, and T-Mobile - has not received its Android Oreo update yet.
