Used storage = very wrong maths

[sgotttttt]

my phone doesn't seem to know where any of the data taking up all of it's space is...

Last week i deleted a lot of videos and that freed up a small amount which has re-filled since, all by itself. Its as if something just fills it with nothing data that is secret

That does look odd indeed. Are we seeing the whole picture in that screenshot or can you scroll to see more items?

Also, can you install this app (developed by @scary alien) and copy/paste the results into a post here?

Also, here is a really good thread about this issue on our forum directly related to this app that might help answer some questions you have:

One of the best tools for looking at what you have used is DiskUsage:
