Select Quick Ball Shortcuts auf Xiaomi
The Quick Ball, also called Access Tool, is a floating button that MIUI places over every screen. It gives fast access to a small, fixed set of actions instead of forcing you to open the notification shade or an app drawer.
That convenience comes with a limit: the panel behind the ball only shows five fields at once. There is no way to add a sixth shortcut without first removing one of the existing five, which is why picking a replacement always overwrites a previous choice.
To change what the ball offers, open Settings ➔ Additional settings ➔ Quick ball ➔ Select shortcuts. From there, tap the shortcut you want to remove, then choose the new function you want in its place.
This setting only rearranges the five available slots. It does not create new shortcuts or extend the panel, and it does not affect other floating tools like screen recording controls or the notification shade.
If the Quick Ball keeps resetting to default shortcuts, check whether a system update reset app permissions tied to Additional settings, since that can silently restore the original five entries.
