I've been having some issues with the storage on my Fire. It's a Fifth Generation, and despite the addition of an SD card and deleting virtually everything, it still remains in critical storage; in fact, whenever I do delete something to clear up space, it seems to add. Not to mention that there are some things that I'll delete and they simply don't go away; some will even return after a couple days.
At that, it generally just seems to fluctuate at will. I've managed to download an app that would clear out files and another to search for viruses. No viruses turned up, and the app for deleting things did so to virtually everything. There's more or less nothing left on here, except for those few that just won't delete.
Does anyone have any help?
