Hide and Show Apps on the Home Screen auf Xiaomi
On Xiaomi phones, hiding an app from the home screen only works once App lock is active. Without it, MIUI has no way to link a hidden app to a password or pattern, so the hide option stays greyed out or missing entirely.
App lock adds a security layer on top of individual apps. Once it runs, MIUI can move an app icon out of the launcher while keeping the app installed and functional in the background.
To hide an app, go to Settings ➔ Apps ➔ App lock ➔ Hidden apps and enable the app you want to remove from view.
To bring a hidden app back, place two fingers on an empty spot of the home screen and pull them apart. MIUI then asks for the App lock password or unlock pattern before it shows the hidden apps again.
This method only hides the icon. It does not stop notifications, background data usage, or the app appearing in storage and battery statistics. If you need to fully remove an app instead of hiding it, uninstalling is the better option.
