Clear cache of apps
.
Add more storage in Memory Card and move apps/data there

Try to clear data of the used apps and
Uninstall unsed data clear apk files which fills the storage
Restart the device
Sometimes it automatically cache memory
And at last ,try to expand memory card to 128 gb becoz u got 64 gb device

Take backup to memory card by samsung smart switch app.its easy process.go to settings then account and backup and then External storage transfer.
After backup format your phone n then reinstall backup data from memory card.
its very convenient process.
You don't have to do anything after reinstalling backup data.
After completing all process move all your media files i e music videos images to memory card
