Add widgets from the Galaxy home screen editor, adjust supported sizes, and set Gallery photos as home screen or lock screen wallpapers. Understand how cover screen settings differ.

Applies to

Galaxy phones using the default Samsung One UI home screen, based on Samsung's current home screen guides. Foldable cover screens, lock screens, and regional options require separate checks.

Based on official documentation, without hands-on testing of every device. Styling and troubleshooting tips are editorial suggestions.

Add widgets from the home screen editor

Not every widget can be freely resized. Its settings menu may also offer background or transparency options, depending on the widget.

  1. Hold an empty area of the home screen and open Widgets.
  2. Find an app and expand its widget styles. Choose a size and add it to the home screen.
  3. If resize handles appear, drag them to adjust the space used. Hold the widget to move it.

  2. Choose a saved image from Gallery and confirm your selection.
  3. Choose the lock screen, home screen, or both, then open the preview.
  4. Adjust the crop and position, check text placement, and tap Done.

Distinguish the home screen, lock screen, and cover screen

These steps focus on the home screen where app icons live. Galaxy lock screens have their own widget options, and foldable cover screens have separate supported lists. They do not automatically inherit all home screen widgets.

For MuseScreen or another app, first check that the target screen's system list includes the app, then choose a style. This guide explains system menus and does not promise third-party cover screen support.

Make space before choosing colors

Styling tip: place everyday widgets on an easy-to-find page with enough open space. Keep weather numbers and calendar text away from the brightest, most detailed wallpaper areas. Also check dark appearance after setup.

Frequently asked questions

Why can I not make the widget larger?

Resizable Samsung widgets show border handles. If none appear, the style may not support resizing. Return to the widget list and choose another size instead of repeatedly dragging it.

Why is a saved picture missing from the wallpaper list?

Troubleshooting tip: open the picture in Gallery to confirm it is on the device, then select it through the Gallery option in wallpaper settings. Check the file location, photo permissions, and whether saving finished.

Find your setup method, then your style

Explore wallpaper previews and styling ideas, then save a suitable image to your device. App features depend on the version you have installed.
