@jt7783: To assign an SD card as the default storage location for your photos and videos, please open the Camera app > Tap the cog symbol in the top left > Storage Location > SD card. This is the only default storage option for SD cards, however you can manually move any items across via Apps > Samsung (folder) > My Files > Documents (as an example) > Tap the 3 dots in the top right > Edit > Select a document > Move (at the bottom of the screen) > SD Card. I hope this helps.
