Leaker Ice Universe says the differences between One UI 9 and One UI 9.5 are minor, according to his post on Weibo. The comparison, posted on November 6, uses two screenshots taken on a Galaxy S26 Ultra, one on each version, and its conclusion is that the changes aren’t significant. It comes right after the small Clock app changes spotted in early One UI 9.5 software, and it has led to talk that Samsung is concentrating on One UI 10 instead.
| Detail | Status |
| Ice Universe’s view | One UI 9.5 changes are minor |
| What was compared | One UI 9 and 9.5 screens on a Galaxy S26 Ultra |
| One UI 10 claim (October 17) | “Significant changes, unprecedented in nature,” per an independent source |
| Possible One UI 10 debut | Galaxy Z Fold 9, per his one-word reply |
| Expected timing | Around mid-2027, not confirmed |
| Android base | Android 18, expected |
| Samsung confirmation | None |
The screenshots look at Samsung Health, where the card layout, colors and rounded elements look similar in both versions. That is a limited test: they don’t show the settings, notification panel or home screen, and some Health improvements, such as trend charts and sleep tracking, already arrived with One UI 9. So the comparison says little about the rest of One UI 9.5, which has other changes like the App Lock feature and a new look for some controls. The idea that Samsung is holding its biggest work back for One UI 10 is an interpretation of the leaks, not a confirmed plan.
On One UI 10, Ice Universe said on October 17 that an independent source had confirmed “significant changes, unprecedented in nature.” When a follower asked whether it would debut on the Galaxy Z Fold 9 or the Galaxy S28, he replied “Fold9,” which points to summer 2027, when Samsung usually launches its foldables. He didn’t describe any features, so the nature of the changes is unknown. An earlier rumor claimed Samsung might rebrand the software as Galaxy OS, but nothing confirms that, and Samsung hasn’t said One UI will go away.
One UI 9.5 itself is still in testing, with a beta possibly starting in late November or early December and a stable release expected on the Galaxy S27 series in early 2027. Samsung’s most recent test build is the new firmware for the Galaxy S26 Ultra. Until Samsung publishes a changelog, both updates should be treated as rumor.
