Galaxy S25 Ultra One UI 9 Updates: The Beginning Kellen | usagoldmines.com

In a surprising turn, the Galaxy S26 series is not the only big series of devices from Samsung starting to receive One UI 9 updates today. The Galaxy S25 series in Korea is also seeing stable updates, which is still very limited in scope, but certainly the beginning of things to come for US units.

The Galaxy S25 One UI 9 update has an official changelog and build number in Korea as S938NKSUCDZIF (Galaxy S25 Ultra).

The update, at least so far, might only be hitting One UI 9 Beta Program testers with Galaxy S25 units in Korea, as the first few updates we’ve seen are only 534MB. For those not in the beta, we have seen the update on Galaxy S26 units reach close to 4GB in size.

The wildest part of this timing is the fact that Samsung only allowed the Galaxy S25 series into the One UI 9 Beta Program at the beginning of this month and yet here we are seeing stable builds already. I guess that would suggest that most of the testing was done through the Galaxy S26 series, which first had beta access back in May.

Below, we have Samsung’s official One UI 9 and Android 17 changelog for the Galaxy S25 series (translated):

One UI 9

AI privacy alerts
