Thanks for being with Samsung and sharing your concern. We would like to inform you that Secure Folder protects your private content and apps, such as photos and contacts, from being accessed by others. You can keep your private content and apps secure even when the device is unlocked. The following actions are an example of moving an image from the default storage to Secure Folder.
1 Launch the Secure Folder app and tap Add files.
2 Tap Images, tick images to move, and then tap DONE.
3 Tap MOVE.
