You Can Now Install Android Oreo on the AT&T Samsung Galaxy S7 & S7 Edge
The path to Oreo has been a bit rocky for the Galaxy S8 and S8+, with Samsung suspending the rollout days after announcing it. Meanwhile, there is still no word about when last year's Galaxy S7 and S7 Edge will get Oreo. We do know for a fact that they'll get it because a user from Vietnam accidentally received a developer version of Oreo on his Galaxy S7.
With the Oreo update, comes Samsung Experience 9.0 which brings a new keyboard, the App Pair feature from the Samsung Galaxy Note8 and much more. The build also comes with the latest February security patches.
If you're a Galaxy S7 or S7 Edge user (AT&T devices only) and don't wait for Oreo, you can install it yourself, thanks to our friends over at XDA developers. The update was pulled from the ATT servers and perfectly safe. It is a pre-release build so it might be unstable and have a few bugs here and there. The only way to install this is if you have a Galaxy S7 or S7 Edge running the latest version of Nougat.
