Update: uninstalling and reinstalling it worked, for brave taking up 16 GB. Unfortunately, now there’s a bunch of garbage system data that I can’t access.
The record in the file system structure, of the existance of the file, is removed, but the space that the file occupied, for some reason , continues to exist. Over time, that occupied space accumulates.
That occupied space grows quickly, when the user is in the habit of downloading files, storing them on their Android or iOS device, and then deleting the files.
I tested that, by using an iPhone to download large installers of Internet browsers (such as Firefox for desktop computers), and then deleting the installer files.
Uh . . . no. Best I can do, is the Apple recommended restart. iOS > Settings > General > Shut Down . . . provides the slider switch, that I think is easier on things -vs- the button pressing:
Well, that didn’t work. I did ask someone else, and they said backup and restore. I believe that would be the best solution. My only issue is my cord. It’s not very reliable.
Myself, I would not try a restore, except in some kind of an emergency. That is a lot more work, because not everything is backed up via the Apple way.
I know, which is why I want to find an alternative way. Something like this did happen before (but not for brave), and I think I fixed it by transfering a few videos to my computer, then deleting them while it was still plugged into my computer. I’m not 100% sure though.
