Samsung is rolling out the One UI 8 update for its Galaxy S23 and Galaxy S24 series devices ‘again’, following a short pause — first to South Korea, at least. The software is reportedly shipping with the August 2019 monthly security update, so this wider, phased release could be on the cards very soon once those initial tests come back clear.
According to the tip and user reports from XDA, as well as the Samsung Members community forum, both series are now once again eligible for the Android 16 update download. Users in the United States and European markets say they’ve yet to see the package, a standard wait as Samsung wraps prospective staged approvals with carriers and regional teams.

Rollout Resumes In Korea After Temporary Halt
Screenshots shared by popular Samsung trackers depict the update already rolling back to Korean units of the Galaxy S23 and Galaxy S24. That’s consistent with Samsung’s historical modus operandi, where it tests the waters in its own backyard before ramping up elsewhere. The company did not publicly explain why it had paused the push, but such holds are typically enacted to fix edge-case bugs that have been called out in early adoption complaints.
Expect a rolling schedule: unlocked variations of said devices usually get the go-ahead first, and carrier versions follow when the testing process is through. The dates are staggered, with international expansion following in waves over several days (some carriers take longer due to additional testing), based on past major launches.
One UI 8 Features That Come To S23 And S24
Changelogs depend upon the region, but One UI 8 for Galaxy S23 and S24 is based on Android 16, which means a lot of focus has been put on stability, performance enhancements, and working through privacy-related issues. We’ve got smoother animations, better power management in the background through more efficient apps, and revamped system apps coming your way! Camera processing on the latest Galaxy flagships is frequently tweaked when major builds roll around, early impressions suggesting more consistent exposure and sharpening in difficult lighting.
Security hardening is another theme. Android 16 brings more control over runtime permissions and foreground service behavior, and Samsung slots in Knox-based policy updates around secure folders and enterprise features. Like any big-platform leap, the download is large; expect to need several gigabytes of available space and a Wi-Fi connection.
Why There Are Pauses Between Major Updates
Phased rollouts with automatic throttling are often used by Samsung when the rates of anomalies increase, the report added. Should telemetry or user feedback reveal that something is amiss (like battery drain, app crashes, sensor oddities) in the new SW at large scale, they can throttle down distribution or pause it until a hotfix for that specific payload is created. The same thing happened on some devices during certain waves of previous One UI releases, where incremental updates fixed issues before deployment began again across regions.
It minimizes the danger of catastrophic failure throughout an enormous installed base. Samsung sells an estimated hundreds of millions of smartphones each year, and a small bug that affects even 1% of those is a lot of people. That is why staged deployment and rapid feedback loops are standard for all major Android vendors now.

Availability And What Users Should Do Next
Owners of the Galaxy S23, S23 Plus, S23 Ultra, S24, S24 Plus and S24 Ultra in Korea will see the update first, with it then rolling out to Europe, India and North America. Carrier variants may be behind unlocked models since the former require certification. If you haven’t received the update yet, head on over to Settings > Software update and be sure to have enough battery life (and storage) before installing.
As always, back up your data (to Samsung Cloud, Google One or local storage) before following through with this. How many thousands more rays of sunshine can shine down upon the iPhone 11 and iPhone 11 Pro this week? If you depend on specialized accessories or enterprise apps, it’s a good idea to check for compatibility, or wait a few days until early adopter reports start coming in. With respect to small cross-app conflicts, users on company forums generally collaborate in such a way that they come up with workarounds rather quickly.
What This Means For Samsung’s Update Promise
The phased-in release continues to see Samsung comply with its software promises too. The Galaxy S24 lineup comes out the gate with an extended commitment of long-term OS and security support, while the Galaxy S23 family still falls within its guaranteed upgrade window. Releasing Android 16 through One UI 8 reiterates the company’s commitment to bringing major Android updates to many devices and on the earlier side of a device’s life.
There’s also talk that the follow-up, One UI 8.5, has been delayed from previous expectations as focus is shifted onto getting the base release stable and in line with upcoming flagship plans.
That wouldn’t be surprising, based on Samsung’s newfound penchant for reliability over rapid-fire feature drops.
Bottom line: Galaxy S23 and S24 owners should expect to see One UI 8 land outside Korea soon as Samsung opens the floodgates. If you don’t have it yet, keep calm — these are typically “phased rollouts,” and although they can take a while to reach everyone, they’re usually better for overall upgrade quality.
