Right now this is being tested on the DBT server for the S9+.
In the last couple of days there are frequently new Android 10 builds showing up. Same goes for the Korean model and the US unlocked model.
Plans are which I have from an insider source at Samsung that they are planning on releasing the stable version for the S9 in January 2020 which would be really fast for Samsung.
For the S10 and Note 10 series they want to rel EW as it in December.
My guess is we will see the S9 getting the beta around November maybe early November or so.
It's not officially stated if the S9 and S9+ or Note 9 will get a Beta program though. Would make sense as last year the S8 and Note 8 got in and even some A series phones. Maybe Samsung Discovered through last year thanks to good interest and input that with more beta programs for more devices they can fix bugs faster and release the sable version quicker.
Good news Galaxy Note 9 and Galaxy S9 owners: Samsung will soon be starting the Android 10 and One UI 2.0 beta program for its 2018 flagships. The company’s ‘beta operations manager’ on the Samsung Korea community website confirmed to a user that the Galaxy Note 9 beta program will kick off sometime later this week while the Galaxy S9 beta will arrive next week.
Maybe we're getting next?
Of course we are getting it next. Thats why I posted it.
Okay this is epic
Beta is live in India as well
Samsung has released the Android 10 update for the Galaxy S9 and Galaxy S9+. The update is rolling out in Germany at the moment for those who are on Android Pie. Yes, the final build of Android 10 is yet to be released for those who are on the One UI 2.0 beta, though that is probably going to change soon.
