Samsung One UI 8.5 Update: A Mixed Bag of Fixes and Fresh Frustrations

Samsung officially began the stable rollout of One UI 8.5, its Android 16-based software, on May 6, 2026, targeting the Galaxy S25 series first in South Korea before a wider global launch on May 11 . Positioned as a stability and refinement update, the release was intended to squash persistent bugs and polish the user experience after an unusually long beta cycle. However, user reports from forums and tech publications in the weeks following the launch paint a more complicated picture. Early adopters have encountered a mix of genuine improvements and frustrating new issues, particularly in dark mode behavior and camera functionality.

Which Galaxy Devices Get One UI 8.5 First?

The first wave of the stable rollout prioritizes Samsung’s current-generation flagships. According to Samsung’s official announcements, the following devices were in the initial phase :

• Galaxy S25, S25+, S25 Ultra, S25 Edge, S25 FE
• Galaxy S24, S24+, S24 Ultra, S24 FE
• Galaxy Z Fold 7, Z Flip 7
• Galaxy Z Fold 6, Z Flip 6
• Galaxy Tab S11 series
• Galaxy Tab S10 series

Reports indicate that the Galaxy S23 series, Galaxy S23 FE, and some additional foldables like the Z Fold 5 and Z TriFold are also confirmed or already updating in many regions, with mid-range A, M, and F series phones expected to follow later .

The Real-World Benefits: Smoother Performance and Smarter Fixes

Users updating to the stable build should notice several concrete improvements that address long-standing annoyances:

• A Fix for Gamers on DeX: A particularly stubborn bug caused the screen to sleep mid-game when using gaming peripherals or DeX. The previous workaround involved toggling the “Stay awake” developer option. One UI 8.5 resolves this natively, keeping the display active as expected .
• Unified Dark Mode Icons: The update can force dark-themed icons on the home screen for all apps, creating a more cohesive look in system-wide dark mode. This feature had been in development throughout the beta phase .
• Security and Stability Overhaul: The package bundles 55 security patches (dated to the January 2026 cycle) that cover vulnerabilities across Android, One UI, and Samsung Semiconductor components . Alongside this, users generally report smoother UI animations and more reliable multitasking .
• New Galaxy AI Experiences: The update also expands a selection of Galaxy AI tools focused on communication and creative tasks across supported phones and tablets .

Fixed Bugs: What the Beta Cycle Eliminated

Samsung’s multiple beta releases (versions 1 through 7) worked through a long list of functional problems before the stable build arrived. Among the confirmed fixes were :

• A malfunctioning proximity sensor that sometimes switched voice calls to video calls unexpectedly.
• Failure of the system color palette to apply correctly to Google Mobile Services (GMS) apps inside the secure work or security folder.
• Gmail’s dark mode search box, which previously had near-invisible contrast.
• Gallery app stuttering during live effects and crashes when starting new projects.
• Lock screen clock glitches, unreliable widgets, and incorrect toast pop-ups during DeX connections.
• Excessive background battery drain from specific apps.

Fresh Complaints: Dark Mode Clashes with Google Apps

Despite these fixes, the stable release introduced an immediate and visible problem: dark mode breaks inconsistently across several Google applications. The root cause appears to be a software conflict between Samsung’s updated default color palette and Google’s Material You dynamic styling system . Users report incorrect grey backgrounds, failure of the dark theme to apply fully, and overall visual inconsistency in apps like Google Search and Chrome.

As of late May 2026, Samsung has not released an official patch. Two manual workarounds exist:

1. Use the Shizuku tool (specifically a forked version created to revert to the pre-One UI 8.5 color set) .
2. Manually override the conflict by adjusting the Color Palette tool in the device’s Settings menu .

Fresh Complaints: Camera Features Go Missing

Camera and photo-editing functionality is the second major source of user frustration with One UI 8.5. Reports have identified several issues:

• Video Filters Vanish: After installing the stable update, several popular video filters are missing from the native Camera app’s interface when in video mode. It is not yet clear whether this is a targeted design change or an unintentional firmware bug .
• Enhance-X Editing Tools Removed: The Galaxy Enhance-X photo editing app still shows as installed, but its Filter Styles and Glow editing options have disappeared following the update .
• Unpopular Reorganization: During the beta phase, Samsung quietly removed the widely used Single Take and Dual Recording modes from the Camera app’s default “More” tab. After significant user protests, these were restored—but they are now buried inside the “Additional modes” menu within the Camera Assistant app, rather than being directly accessible. Even in the stable release, users and reviewers have criticized this implementation as clunky and half-baked .

Battery Drain and App Stability: Standard Post-Update Gripes

Finally, a consistent subset of users on community forums report aggressive battery drain shortly after installing One UI 8.5. Samsung’s longstanding advice—to wait 7–14 days for background optimization processes to finish after a major Android version update—remains relevant here . However, some general app crashes and intermittent stability hiccups have also been flagged, indicating that the refinement process is not yet fully complete .
