Summary
(AI)
The update started in South Korea on October 14, aimed first at phones already enrolled in the beta program. The stable release ends the beta for these phones. The rollout then widened on October 19 and 20, when coverage reported it reaching regions outside South Korea.
Europe appears to be the first region outside South Korea to get it. SamMobile says Samsung seems to be sending the update to beta users first. Wider availability for everyone else has not been confirmed by coverage, though GSMArena says it should expand to non-beta users. The coverage does not give dates for specific countries or carriers.
