Samsung One UI 8.5 Update Causes Broken Dark Mode & Ugly Grays in Google Apps

Samsung’s One UI 8.5 update has introduced a widespread visual bug affecting Google apps on Android devices, leaving users frustrated with inconsistent dark mode styling and unnatural gray tones. Reports from Galaxy S25 owners—and other affected models—describe a clash between Samsung’s One UI framework and Google’s Material You dynamic theming system, forcing high-contrast grays onto apps like Gmail, Google Messages, and Google Keep. The issue persists even after applying Samsung’s Theme Park adjustments, leaving users without an official fix. ### A Clash of Theme Engines The problem stems from a conflict between Samsung’s One UI 8.5 and Google’s Material Expressive framework, which dynamically adjusts UI elements based on wallpaper colors. While Google’s system is designed to blend seamlessly, Samsung’s implementation appears to override these settings, imposing a rigid gray palette that disrupts the visual harmony of Google’s apps. Users report that search bars, menus, and text elements now appear dull or overly contrasty, making readability uncomfortable. Samsung’s Theme Park tool, which allows users to customize device aesthetics, fails to mitigate the issue. The inconsistency is particularly jarring when comparing Google apps to other native Samsung applications, which retain their expected dark mode styling. ### No Official Fix—Workarounds Exist, But Are Unreliable As of May 25, 2026, Samsung has not issued an official patch or statement addressing the bug. Users are advised to submit feedback through Samsung’s support channels to expedite a resolution. For those unwilling to wait, a Reddit user named MohamedElngar21 has shared a workaround involving ADB and Shizuku—a third-party tool—but this method requires technical familiarity and may not be sustainable long-term. The workaround’s reliance on unofficial tools highlights the lack of a native solution, leaving users vulnerable to further instability if Samsung does not prioritize a fix. Given the widespread impact across multiple device lines, including flagship models like the Galaxy S25, the issue raises questions about Samsung’s quality assurance processes for major software updates. ### Broader Implications for Android Ecosystem This incident underscores the growing complexity of Android’s fragmented software landscape. While Samsung’s One UI and Google’s Material You are designed to coexist, discrepancies in implementation can lead to unintended visual and functional inconsistencies. For users, the bug serves as a reminder that even stable updates can introduce regressions, particularly when multiple theme engines interact. Developers and power users may also face challenges, as the issue could extend to third-party apps relying on Material You for theming. Samsung’s delay in addressing the problem may further erode trust in its update cycle, especially among users who prioritize visual coherence in their devices. ### What Comes Next? Samsung has not confirmed a timeline for resolving the issue, but the company’s history suggests it will eventually release a patch. Until then, affected users must weigh the inconvenience of the bug against the risks of unofficial fixes. For those seeking immediate relief, reverting to an earlier One UI version remains an option, though it may not be ideal for long-term use. The incident also serves as a case study in the challenges of maintaining visual consistency across Android’s diverse hardware and software ecosystem. As both Samsung and Google continue to refine their respective frameworks, collaboration between manufacturers and platform providers will be critical to preventing similar issues in future updates.
