My s7 has 32gig out of storage but only count 8gig of usage?

I'm not sure when I calculate my storage it not even near to 10gig yet still my storage is saying 27gig/32gig used.

Android system takes about 12 if that helps and cached data takes up another 2 on my phone as well. Samsung may use more with all their optimizations & addons. But you should see that listed too.
If you scroll down there should be an Explore option so you can go thru the various folders. I didnt realize that i have photo on my internal memory. I need to move those to my SD card so they get backed up with the rest.
