What the New Theme Park Update Brings to One UI 9
Samsung’s updated Theme Park app for One UI 9 is a Good Lock module that lets users design and apply custom themes, colors, icons, and keyboard styles that go beyond stock Samsung device themes and the default wallpaper-based theming options. With the latest version (1.1.02.01), Theme Park adds enhanced customization options tailored for One UI 9 devices, while still supporting earlier One UI releases. The app now focuses on deeper One UI customization features: refined color tuning, better theme quality, and smarter system icon behavior. It is available through the Galaxy Store and integrates with the wider Good Lock ecosystem, so users can pair visual tweaks from Theme Park with layout and behavior modules like Home Up or LockStar. In short, it turns One UI 9 personalization into a granular, design-level toolkit rather than a simple theme picker.
Enhanced Keyboard Customization with New Keycap Designs
One of the standout additions in the new Theme Park app customization update is deeper control over the Samsung Keyboard on One UI 9. Version 1.1.02.01 introduces new keycap designs that allow you to shape how individual keys look, not only the background behind them. This makes it easier to match your keyboard to a custom color palette or icon pack, instead of accepting a generic layout. You can fine-tune visual details so the keyboard feels like part of your overall theme rather than a separate, fixed element. According to SamMobile, the latest Theme Park release “brings enhanced keyboard customization with new keycap designs for Samsung Keyboard on devices running One UI 9.0.” When combined with Good Lock’s other modules, this helps your typing experience line up with the rest of your interface styling.
Smarter Live Icons for Calendar and Clock
Theme Park’s update also improves how live icons behave for Samsung’s stock Calendar and Clock apps, a key win for One UI 9 personalization. Previously, applying a theme pack could cause these icons to stop showing the correct date or time, breaking useful glanceable information. The new version refines icon previews so themed icons stay dynamic and functional while still matching your chosen design. You get consistent iconography across the home screen and app drawer without sacrificing live data. This makes Samsung device themes feel more polished, especially when you use complex icon sets. The change also means fewer compromises: you can safely explore bold icon packs through Theme Park without worrying that essential live icons will lose their real-time updates or become visually out of place.
Improved Color Tuning and Theme Quality Across Devices
Beyond icons and keyboards, the latest Theme Park release focuses on color accuracy and overall theme polish. Samsung notes that it has improved color tuning and overall theme quality for devices on both One UI 9 and earlier versions, so even if you have not updated to One UI 9 yet, you still benefit. The updated engine interprets your chosen palette more reliably, reducing odd contrasts or mismatched accents across system menus, quick settings, and notifications. This makes custom themes feel closer to native skins instead of add-ons layered on top. For users who care about cohesive One UI customization features, the difference shows up in subtle details: more consistent background shades, legible text in dark or light modes, and smoother blending between themed and unthemed elements.
How Theme Park Fits into the Good Lock Personalization Stack
Theme Park’s One UI 9 upgrade underlines its role as the visual anchor of the Good Lock ecosystem. While other Good Lock modules tweak behavior, layouts, and lock screen interactions, Theme Park focuses on color, icons, and UI surfaces, creating a base layer of style for your Samsung device themes. You can design a theme in Theme Park, then refine your home screen grids in Home Up and adjust lock screen details in LockStar, building a cohesive, deeply customized setup. Because the app is designed with One UI 9 in mind but still improves theme quality on earlier versions, it serves as a bridge for users upgrading across devices. For anyone who wants fine-grained One UI 9 personalization that goes further than Samsung’s standard Appearance settings, Theme Park has become an essential starting point.
