Icon Autofill Setting auf Realme
On Realme phones running Realme UI, the home screen keeps itself tidy by default. When an app gets removed, the icons that come after it shift left to fill the gap automatically. This behavior is controlled by a single setting called Icon autofill.
With Icon autofill turned on, every uninstall or shortcut removal triggers an automatic reflow of the remaining icons across your home screen pages. That is convenient if you do not care about exact icon placement, but frustrating if you organize apps into specific spots or leave gaps on purpose for visual grouping.
Turning the setting off stops this automatic rearranging. Removed apps simply leave an empty space where they used to sit, and nothing else moves until you drag icons yourself.
To change it, go to Tap on Settings ➔ Tap on Home screen & Lock screen ➔ Enable or disable Icon autofill. The toggle applies immediately, so you can test both states before deciding which layout behavior fits how you use your home screen.
