After rolling out Android Oreo to the Galaxy A5 (2017) and A7 (2017), Samsung is distributing the update to the Galaxy S7 and S7 Edge. Weighing in at around 1.3GB, the update includes Android Oreo, Samsung Experience 9.0, and the April 2018 security patch.
As of this writing, the update is rolling out to the UK, so you will need to wait a little longer for this update.
