What the New Theme Park App for One UI 9 Does
The updated Theme Park app for One UI 9 is a Good Lock add-on that lets Samsung users personalize system visuals such as colors, icons, and keyboard elements far beyond the default customization options available in standard settings. By integrating with One UI 9’s design system, it gives users deeper control over how their Galaxy device looks and feels day to day. Theme Park now focuses on three main upgrades: enhanced keycap designs for Samsung Keyboard, improved live icons and previews for Calendar and Clock, and better color tuning for themes. These improvements arrive with version 1.1.02.01 of the Theme Park app, which is available through the Galaxy Store for devices running One UI 9. The app still supports older One UI versions, but specific new features like the updated keyboard customization are exclusive to One UI 9.
How to Install or Update Theme Park on One UI 9
To use the latest Samsung Theme Park features on One UI 9, start by opening the Galaxy Store on your Galaxy device and searching for “Theme Park.” If you already have it, tap Update; if not, install it as part of the Good Lock family of tools. Once installed, open Good Lock, scroll to Theme Park, and launch it from there. Make sure your device is running One UI 9 to unlock the newest options, especially the enhanced keyboard customization. On older One UI versions, Theme Park still works but certain additions will not appear. According to SamMobile, the June 2026 release of Theme Park (version 1.1.02.01) brings these new customization features along with general bug fixes and usability improvements. After confirming the update, restart Theme Park so that it can reload themes and apply the refreshed design system correctly.
Customizing Samsung Keyboard with New Keycap Designs
The standout One UI 9 customization in this release is deeper control over Samsung Keyboard. Open Theme Park, select the Keyboard module, and choose Create New or edit an existing layout. You can now change keycap shapes, outlines, and colors with more precision, tailoring everything from background tones to pressed-key effects. On One UI 9 devices, the updated Theme Park lets you preview these changes in real time, so you can see how letters, symbols, and spacebar styles will look before saving. To build a cohesive look, pick a base color that matches your current theme, then adjust accent colors for special keys like Shift and Enter. When you are satisfied, tap Save and apply your keyboard theme. The new keycap engine is exclusive to One UI 9, so you need the latest system version to see the full range of keyboard options in Theme Park.
Improving One UI Personalization with Live Icons
Theme Park’s latest update also refines live icons for the stock Calendar and Clock apps, which are essential to One UI personalization. In earlier versions, applying icon packs could interfere with live updates, causing the Calendar icon to stop showing the current date or the Clock icon to lose its live time display. The new Theme Park version improves how these icons update while themed, keeping both style and function. To adjust icons, open Theme Park and choose the Icons section, then build or edit an icon theme. Apply your preferred shapes and colors, then check the preview area: Calendar and Clock should now show accurate live information even when themed. This helps your home screen stay both colorful and informative. If something looks off, tweak the color contrast or switch to a simpler icon style so that dates and clock hands remain clear on your chosen background.
Fine-Tuning Colors and Theme Quality Across One UI
Beyond individual features, the updated Theme Park app improves overall color tuning and theme quality across Galaxy devices. When you create a new theme, Theme Park now reads One UI’s system palette more precisely, producing coordinated shades for quick settings, notifications, and app backgrounds. This means fewer mismatched elements and smoother transitions between light and dark areas. Samsung notes that these color improvements apply to both One UI 9 and earlier versions, though One UI 9 devices benefit most thanks to tighter integration with the latest design system. To build a theme, open Theme Park, select the overall Theme module, choose a wallpaper, then let the app generate a base palette. You can tweak primary and accent colors, preview how they look in key screens, and then save your theme. Apply it from within Theme Park or through the Themes section in system settings for consistent One UI personalization.
