After the update was released to Sprint, T-Mobile, and Verizon in the last few days, AT&T has finally begun rolling out Android 8.0 Oreo to the Samsung Galaxy S8 and S8 Plus. The update ships with the February security patch and rounds off the rollout of Oreo for the S8 across all four major US carriers.
With Oreo on the S8 and S8 Plus, you get access to features such as picture-in-picture, autofill, improved speed, better battery life, enhanced security, a new UI called Samsung Experience 9.0, App Shortcuts, and more. You can learn more about the update in our Galaxy S8 re-review.
Be sure to jump on Wi-Fi before installing since the update could eat up your cellular data pretty fast.
