What Theme Park Brings to One UI 9 Customization
Theme Park is Samsung’s theme-creation app that lets you redesign the look of One UI by building custom themes, changing colors, and adjusting interface elements without needing to root your phone or install complex tools. In its latest update for One UI 9, Theme Park adds enhanced customization options that make it a practical alternative or companion to Good Lock for One UI personalization. Instead of hunting through hidden menus, you can shape your Samsung phone themes from a single, focused app. The June 2026 release (version 1.1.02.01) is “designed with One UI 9 in mind” and introduces better keyboard styling, improved live icons, and refined color tuning. This makes Theme Park a central hub for users who want deeper One UI 9 customization with clear previews before they apply changes.
Getting Started: Install and Open Theme Park
To start redesigning your interface, install or update Theme Park from the Galaxy Store, then confirm you are running One UI 9 for access to the newest features. Once the app is up to date, you will see separate panels for themes, icons, and keyboard styles, each guiding you through One UI personalization step by step. Theme Park sits inside the Good Lock family, but you can open it directly, so you do not have to browse every Good Lock module to find relevant options. From the main screen, tap the plus button in the Themes or Keyboard sections to create a new profile. Theme Park then scans your current wallpaper and suggests a color palette, giving you a quick starting point for building custom Samsung phone themes that match your background.
Design Custom Themes: Colors, Icons, and Live Previews
Theme Park’s core strength is letting you design complete Samsung phone themes that suit your taste instead of relying on premade packs. Start a new theme and adjust system colors, quick panel accents, and app backgrounds based on your preferred palette. The latest update improves color tuning and “overall theme quality” across One UI 9 and earlier versions, so gradients and highlights appear more consistent. You can also tweak app icon shapes and apply icon packs while previewing changes in real time. A notable upgrade is the better handling of live icons for the stock Calendar and Clock apps, which previously could lose their live date and time when themed. According to SamMobile, the new version introduces improved live icons and previews for those apps to keep both style and function intact.
Customize Samsung Keyboard With New Keycap Designs
One of the standout Theme Park app features for One UI 9 customization is the enhanced keyboard editor. In version 1.1.02.01, Samsung added new keycap designs for Samsung Keyboard on One UI 9.0, giving you more control over how letters, symbols, and number keys appear. From the Keyboard tab, you can choose different key shapes, outlines, and color combinations, then preview how they will look while typing. You can also sync keyboard colors with your overall theme for a unified appearance across the interface. For power users who previously depended on Good Lock modules to change keyboard styling, this update makes Theme Park a strong alternative. Instead of switching between apps, you can build a cohesive typing and system look in one place and save multiple keyboard styles for different moods.
Using Theme Park Alongside or Instead of Good Lock
Theme Park does not replace Good Lock, but it can reduce how often you need to open other modules when focusing on visual One UI personalization. Use Theme Park as your primary tool for Samsung phone themes, icon styles, keyboard layouts, and color tuning, then turn to Good Lock only when you need deeper behavior changes such as advanced multitasking or lockscreen controls. Because Theme Park groups appearance settings in one app, it is easier for less technical users to discover options that might be hidden elsewhere. You can experiment with multiple theme profiles, test them using the preview screens, and then apply your favorite across the system. If you stay on One UI 9, keep Theme Park updated through the Galaxy Store so you always benefit from the latest quality and usability improvements.
