Uninstall Secure Folder auf Samsung
Secure Folder isn't a normal app you can long-press and remove from the home screen. It runs as an isolated Knox container, so Samsung only lets you remove it from inside its own settings menu, not from the app drawer.
To uninstall it, open Secure Folder, then tap Open the Menu ➔ Tap on Settings ➔ Tap on More settings ➔ Tap on Uninstall ➔ Tap on Uninstall again to confirm.
Confirming the uninstall deletes every app, photo, contact, document and file stored inside Secure Folder. There's no partial removal - it's the whole container or nothing.
Back up anything you want to keep before confirming, since the action can't be undone once it finishes running.
After the uninstall completes, Secure Folder disappears from your app list. You can set it up again later from your device settings, starting with an empty, freshly created container.
