Step by step

Open Device care
Open Settings and tap Device care. The Storage bar shows how much of the phone is used.
Done
See what takes the space
Tap Storage. The Manage storage page lists audio files, images, videos and documents with their sizes. Tap a category to see and delete its files.
Done
Remove duplicates and large files
Duplicate files and Large files collect the easiest wins. Tap one, select what you do not need and delete it. On our phone Large files, Duplicate files and Trash all showed 0 B, so there was nothing to remove there.
Done
Follow the suggestions
Under Suggestions, One UI offers quick clean-ups, such as archiving apps you do not use (your data is kept) or deleting old images. Ours offered to free up 280 MB by archiving 1 unused app.
Done
Uninstall apps you do not use
Open Settings, Apps. The list shows each app with its size. Tap an app you no longer need and tap Uninstall.
On ours, Spotify's App info had Open, Archive, Uninstall and Force stop at the bottom.
Done
Clear an app's cache
In Settings, Apps, tap an app, then Storage and Clear cache. This removes temporary files only. Clear cache is greyed out when an app has no cache, as Samsung Notes had on our phone. Clear data instead resets the app and deletes its data, so use it with care.
Done

Your phone has a microSD card Samsung says many apps can be moved to the card under Settings, Apps, the app, Storage, Change. If Change does not appear, that app cannot be moved. Files can be moved in My Files. Source: Free up storage space on your Samsung phone or tablet

If this does not work

The space did not come back Samsung says deleted files go to the Trash first (Move to Trash). Empty the Trash in Gallery and My Files to free the space. Source: Free up storage space on your Samsung phone or tablet
The phone is slow rather than full Samsung says Device care, Memory, Clean now stops background apps and frees memory. Excluded apps keeps the apps you want running. Source: Free up storage space on your Samsung phone or tablet
