One UI 9 home screen setup starts with a compatibility check, not a long list of tweaks. Samsung rolls software and Good Lock modules out by model, region, and software version, so a setting shown on one Galaxy phone may not appear on another.
Home Up is a Good Lock module for customizing Samsung's One UI Home. Samsung documents DIY Home, home and app-screen layouts, folder styles, and a way to restore the Home screen layout. Its support page also warns that options vary by device and software version. Check the module on your own phone before following a tutorial made on a different Galaxy model.
Check whether your Galaxy supports it
Start in Settings and note your model and One UI version. Samsung's One UI 9 rollout is gradual, so the version number alone does not promise that every feature has arrived on your device. Check the software-update screen and the Galaxy Store for Good Lock and Home Up. Use the official store listing for your region; do not install an unofficial module package to make a missing option appear.
If Home Up is listed in Good Lock, open its page and check that the module is installed and enabled. If it is absent, first check Samsung's current availability information for your model and region. You can still simplify the standard Home screen with the controls already present in One UI Home.
Samsung's Good Lock guide says Home Up can make a DIY Home, change supported layouts, adjust folder styles, and restore a Home screen layout. Samsung also says Good Lock features can vary by software version and device model. Its One UI 9 rollout notice describes a gradual expansion to more Galaxy devices.
Save the layout before changing it
Take a screenshot of each Home page and note the current grid, dock, and folder arrangement. If your Home Up version offers a layout backup or restore control, use it before trying a larger change. The exact label may differ between releases.
This small record matters when a layout moves after a software or module update. You can compare the new screen with the old one and rebuild the parts you actually miss, instead of trying to remember every icon position.
Make the first page answer one question
Decide what the first screen should help you do. It might be starting a call, checking a calendar, opening a work app, or finding a short list of daily tools. Keep those actions visible and move occasional apps to the app screen or a folder.
Begin with one Home page and a short favorites row. A clock or calendar widget earns its space only if you read it often. If a widget repeats information already visible in the status bar, remove it and use the room for something else.
Choose labels and spacing that stay readable at your usual font size. A tightly packed grid may fit more icons, but it also makes targets smaller and harder to scan. Test the layout one-handed and in bright light before adding more blocks or decorative elements.
Change one Home Up setting at a time
Open the Home Up area that matches your goal, such as Home screen, DIY Home, or folders. Change one setting, return to the Home screen, and check both the Home page and the app screen. If the result is useful, keep it; if it creates extra steps, restore the previous choice before trying another control.
Avoid changing the grid, dock, folder style, gestures, and recent-app screen in one session. When several controls change together, it becomes difficult to tell which one caused a layout shift or an awkward gesture. A short test after each change keeps the setup understandable.
If Home Up does not show the control a tutorial describes, do not assume your phone is broken. The author may have a different model, region, module build, or One UI version. Search the current Good Lock screen and Samsung support page for your device rather than copying a menu path that is not present.
Decide whether a replacement launcher solves a different problem
Home Up changes supported parts of Samsung's One UI Home. A third-party launcher replaces the default Home app and can use a different navigation model. Those are different choices: Home Up is a sensible first stop if you like One UI and want to adjust its layout; a replacement makes more sense when you want text-first navigation, another app-list style, or a different Home structure.
Minimalistic is one text-led Android launcher option. It can present selected apps as a simpler Home list and offers a separate custom home builder. It does not add Home Up features to One UI Home, and switching launchers does not guarantee that every Samsung gesture or widget will behave the same way.
Keep Samsung's stock Home app available while you test another launcher. If you switch, confirm that the Home gesture, navigation bar, widgets, and the route back to One UI Home still work on your model. Use the default Home-app setting to return if the replacement is not a fit.
Review the result after normal use
Use the new layout for a few ordinary days, not only while editing it. Notice whether you can find the apps you need without searching, whether you open fewer folders, and whether the screen remains readable after installing an app or changing font size.
Keep the changes that make daily actions clearer. Restore the rest. A useful home screen is one you can recognize and maintain after the novelty of customizing it wears off.
