If you move photos and pictures to your memory card on your Samsung Galaxy S8, you may notice that the pictures are no longer visible in your gallery app. This often happens when moving large numbers of files at once.
Don’t worry – these pictures aren’t gone forever. Although they don’t display in your gallery app, they are still on your device. The gallery uses a media scanner to determine what images to show, but sometimes it has trouble scanning large numbers of images at once.
To scan all of your new images again, simply restart your Samsung Galaxy S8. By doing this, all of your recently moved images will appear in the gallery app again. We hope we have helped to solve this problem on your Samsung Galaxy S8.
