Change Home Screen Layout auf Realme
Realme UI stores the home screen grid size separately from the icon arrangement itself. If you add more apps than the current grid supports, icons get pushed onto extra pages instead of shrinking to fit. Switching to a denser grid keeps more apps visible per page, while a looser grid gives icons and labels more room.
To change it, open Settings ➔ Home screen & Lock screen ➔ Home screen layout. Pick the number of columns and rows you want, then tap on a free area to exit and apply the change.
The new grid size applies to every home screen page at once, not just the one you are viewing. Existing icons rearrange automatically to fill the updated layout, so some apps may end up on a different page than before. Widgets keep their own size settings and are not affected by the column and row count you set for app icons.
If icons look uneven right after changing the grid, a manual reorder usually fixes it faster than switching the layout again.
