Hey guys, just wanted to know if anyone else has this issue/has fixed it: I've got a 16gb 6s and the thing has 6 GIGS of "other" storage!!!! The only thing that wipes it is a system restore, but that only lasts a week or two. How the hell do I get that storage back? This is a HUGE flaw in iOS!
I think it's mostly just temporary files and the like left by the various apps you have installed. They should show under the storage for that apps, but for whatever reason, that doesn't always happen.
This has been present for years. Only way I have got rid of it is to system restore that I have found. I agree it is a total pain.
