Lock or Unlock Home Screen Layout auf Oppo
The message Home screen locked appears when Oppo's layout protection is switched on. This function stops any change to app shortcuts, widgets, or folders on the home screen, whether that change is accidental or intentional.
Once enabled, you can still open apps normally, but long-pressing an icon to move it, deleting a widget, or dragging a new shortcut onto the home screen simply does nothing. The system treats the entire layout as fixed.
Where the setting lives
The option sits inside the display settings, together with lock screen and Always-On Display controls, since all three deal with how content is shown on screen.
To check or change it, go to Tap on Settings ➔ Tap on Home screen, Lock screen & Always-On-Display ➔ Enable or disable Home screen locked.
Turning the toggle off restores full control over icons and widgets immediately, no restart needed. Turning it on protects a layout you already like, which is useful if children or other family members use the same device.
