Although Samsung began rolling out the One UI 8 update for its flagships in September, some issues began to crop up earlier this month. We saw devices like the Galaxy S24 and the Galaxy S22 have their One UI 8 updates pulled from the servers, with the Galaxy S23 also joining the list earlier this week.
Thankfully, it looks like things are going back to normal, albeit gradually, as Samsung has reportedly resumed the Android 16-based One UI 8 update for the Galaxy S23, Galaxy S23+, and the Galaxy S23 Ultra. This resumption of One UI 8 also comes with the October 2025 security patch, according to Tarun Vats on X/Twitter (via SamMobile).
Of course, most users will already have updated their Galaxy S23 models to One UI 8 when the update began rolling out late last month. But for the holdouts who didn’t take that route, this should be welcome news. The update is rolling out in South Korea, according to Vats, though it shouldn’t take long for other markets to follow suit.
This new update featuring the October 2025 security patch will be around 385MB in size, provided your Galaxy S23 is already running One UI 8. Expect a larger update size if you’re updating from One UI 7, as SamMobile notes.
A wide range of bugs and vulnerabilities have been patched with the October 2025 update, with the full details already live on Samsung’s security updates page. However, there are no significant visual or functionality changes on board if you already have One UI 8 on your Galaxy S23.
If you’re one of those users who didn’t update their Galaxy S23 to One UI 8 when it first began rolling out, head over to Settings > Software update > Download and install to pick up the latest software right away. With the update resuming for the Galaxy S23 lineup, one assumes the Galaxy S23 FE’s update should be back on track as well.
While some have complained of subpar battery life after installing One UI 8, other users have reported no particular issue with the battery. We’ve also seen users report a Bluetooth-related glitch. However, we don’t have a large enough sample size of complaints to determine whether this is what led Samsung to pause One UI 8 for some flagships.
What has your experience with One UI 8 been like so far?
