A newly surfaced software complaint suggests One UI 8.5 may be causing an annoying video playback issue for some recent Samsung flagships. According to user reports cited in the source article, owners of the Galaxy S24 and Galaxy S25 series have noticed that video colors can suddenly change whenever a system overlay appears on screen.
The behavior is said to show up during normal playback. Videos may look fine at first, but the moment a volume slider pops up or a notification banner drops in, the image can shift noticeably. Users describe the picture as becoming overly contrasty, washed with gray, or otherwise different from the original calibration.
What makes the issue especially distracting is how abrupt it appears to be. The source report says the change happens as soon as the overlay is visible, then disappears just as quickly once the volume graphic or notification banner goes away. That means the same clip can keep flipping between two looks during a single viewing session.
For people watching movies, short videos, or live streams, that kind of visual jump can be hard to ignore. It may become even more disruptive when multiple alerts arrive in a short period, since every banner or floating interface element can trigger another color change.
Based on the source material, the issue appears tied to devices that have already moved to the stable One UI 8.5 release rather than a preview build. The report doesn’t say Samsung has issued a formal explanation yet, but the pattern described by users points to a software-level display handling problem instead of a panel defect unique to one handset.
For now, affected users are left watching for a fix. If the report holds up more broadly, Samsung may need to address how the system handles brightness, contrast, or display processing when transient interface layers appear over active video content.
