As we already know that the last day for ending the testing period Android Oreo for Samsung Galaxy S8 and S8 + was instantly set as January 15th, then moved to January 17th and finally it is ended today.
So finally we can say no more beta version will be roll out through OTA. Despite the deadline for beta testing of Android Oreo on Samsung Galaxy S8 and S8 + has been postponed twice, today we finally arrived at its conclusion.
This means that Samsung will no longer release any beta builds and that the next OTA update will introduce the first stable version of Android Oreo for the two, at the moment, Galaxy series flagships.
Unfortunately, no date has been made as to when this will happen, but it is reasonable to expect that the rollout will start soon.
