The Tab S should have a SD card slot. Don't know if you have one installed, but if you don't, you should get one and move all photos and videos to it. You should also back them up somewhere else too (in case the SD fails), like cloud storage, or to your pc. Also, if you have too many 3rd party apps installed, consider uninstalling ones you don't use anymore.
