A Galaxy Tab S9, Tab S10 Ultra or Tab A9+ with a low-storage error can be fixed without deleting family photos. Samsung's article says low space causes crashes, errors and sluggishness, and lists its tools: sync to a cloud service such as Google Drive, OneDrive or Dropbox, use Device care to clean unnecessary files, and use My Files to move or delete items to internal storage, an SD card, Google Drive, OneDrive or network storage. Unlike the iPad, these Samsung tablets have a slot: Wikipedia lists microSDXC up to 1 TB for the Tab S9, a dedicated microSDXC slot on the S10 Ultra and microSD expansion on the A9+ per iFixit.
The Tab A9+ comes in 64, 128 or 256 GB, the S9 in 128 or 256 GB and the S10 Ultra in 256 GB to 1 TB.

What causes a low-storage error while free space shows?+

Storage holds files and apps; RAM is separate. Wikipedia lists 8 to 16 GB of RAM on the S9 and S10 Ultra, and freeing storage does not add RAM.
