Check your device storage you might have some apps that take to much storage
If your device storage is many delete some of the apps to get more storage
I've only used 37.1 GB of the 256 GB available(๑ゝڡ◕๑) AnimeMaker is probably the app I use the most to be honest >< I'm just guessing it's due the the animes having too much color and too many frames.
