Device memory dropped instantly

There was an app that scanned the files system to display the usage by several factors. I have it on my daughter's tablet so I can't remember what it was exactly.

Try looking for file system scanners incase life gets in my way.

 

nobody offering any help to you, just a response to say find a file system scanner which you have already done.

the storage space issues are weird. mine is actively dropping then resetting and going over again.

have you tried plugging your phone into a computer and seeing what the computer reports as the phone memory space available?

 

Is that possible the temp files of your apps take the space?
