Settings > General > Transfer or Reset iPhone> Reset Home Screen Layout:
Function:
- This feature cleans up your Home screen, restoring it to a more organized state.
Effects:
- Built-in Apps: These are the apps that came pre-installed on your device by the manufacturer (e.g., Phone, Camera, Messages). Resetting the layout will return them to their original positions on the Home screen. This can be helpful if you've moved them around and can't remember where they were.
- Downloaded Apps: Any apps you've downloaded from the app store will be rearranged alphabetically. This provides a quick and easy way to find specific apps you need without having to remember where you placed them.
- Folders: Any folders you created to organize your apps will be removed. The app icons within those folders will be scattered across the Home screen and sorted alphabetically along with the individual apps.
- Widgets: While not explicitly mentioned, resetting the layout typically doesn't affect widgets you've added to the Home screen. They'll likely remain in their current positions.
Important Considerations:
- This is an irreversible action. Once you reset the layout, you'll need to manually rearrange everything again if you want a different setup.
- It's a good idea to back up your Home screen layout (if your device allows it) before resetting, in case you want to restore your previous organization.
Alternatives to Resetting:
- Manual Rearrangement: You can simply drag and drop app icons and widgets to reorganize your Home screen without resetting everything.
- Create Folders: Organize your downloaded apps into folders based on category or usage for a more customized setup.

Create folders
- Touch and hold the Home Screen background until the apps begin to jiggle.
- To create a folder, drag an app onto another app.
- Drag other apps into the folder. ...
- To rename the folder, touch and hold it, tap Rename, then enter a new name.
