Theme Park
Theme Park is a Samsung Good Lock module that lets you create custom themes for Samsung devices, including the ability to apply third-party icon packs on OneUI without a separate launcher.
Samsung's OneUI launcher doesn't natively support third-party icon packs the way Nova or Lawnchair do. Theme Park bridges this gap. It's a module inside Samsung's Good Lock app that lets you create custom themes — including fonts, colors, and crucially, icon pack theming.
To use Theme Park: install Good Lock from the Galaxy Store, download the Theme Park module, create a new theme, and under the icon section, choose "Third Party" to select any installed icon pack. Save the theme, apply it, and your Samsung home screen and app drawer will use the icon pack's designs.
This is the recommended way to use One4Studio icon packs (Vera, Lena, Ares) on Samsung devices. It lets you keep Samsung's OneUI features (Edge panels, gesture navigation, etc.) while still getting custom icons across the entire system.
Tip: Good Lock and Theme Park are not available in all regions. If they're not in your Galaxy Store, try "NiceLock" or "Fine Lock" from the Play Store as alternatives that provide access to Good Lock modules.
