Samsung UK Support don’t know when we’ll see the final Oreo firmware for the Galaxy S8
Samsung’s UK Help centre has confirmed it doesn’t actually know when the final release of Oreo will hit the Galaxy S8:
My guess is that it either genuinely isn’t privy to that kind of information or Samsung don’t have a final date yet.
Is the software ready for the mainstream? No, probably not. Is it a long way off? No definitely not.
I’m still going to guess at Jan/Feb 2018 but we’ll just have to keep an eye out on the updates and will update on Android Addicts when I know more.
