No Live Focus mode for the Galaxy S8. Not yet anyway
This doesn't come as a surprise, as implementing a portrait mode with a single camera would take some work. Google has done it with the Pixel 2 and Pixel 2 XL by using the Dual Pixel autofocus system and AI trickery, so it's certainly possible, but we don't see Samsung making it available for any device before the Galaxy Note 8. Well, and even to a phone with a single rear camera that launches in the future, as having two cameras at the back of a phone would be somewhat useless if Live Focus wasn't an exclusive highlight.
But hey, Samsung could make Live Focus available in a newer version of the Oreo beta. Even if it doesn't (and we have no solid reason to believe it will), you do get a slew of other new features and functionality on Oreo.
