Add a New Home Screen Page auf Samsung
Samsung One UI normally creates a new Home screen page by itself once you drag an app or widget onto a page that is already full. This automatic behavior depends on free space detection, and it occasionally fails to trigger, especially after a system update or when the launcher cache gets confused about existing page layouts.
When that happens, apps and widgets you try to place get squeezed onto existing pages instead of moving to a fresh one. Adding a page manually solves this without waiting for the system to catch up.
How to add a page manually
Tap and hold a free area on your Home screen until the edit menu appears, then swipe to the last Home screen. From there, tap on Add to create a new empty page.
Tap and hold a free area on Home screen ➔ Swipe to the last Home screen ➔ Tap on Add
The new page appears immediately and is ready for apps or widgets. If you do not see an Add option, you have likely reached the maximum number of pages allowed on your device, and you will need to remove an unused page first.
