What exactly is "other"

[CoriG]

I backed up my iPhone 6 to iTunes today (I am running PB1) to try to restore it (hoping to work out a few bugs) and iTunes says that "other" is using approximately 21.5 gigs (out of 128 gigs) of space. What exactly is "other"? Does that seem a bit too high? I do not remember it being that high when I was on 8.4. Anyone have any suggestion?

Thanks!

Crap, leftovers of a not so good OS.

System leftovers (because its a beta), app caches, etc.

As far as app caches, iOS will clean those automatically as system storage runs low (a feature I'd rather have control over). The other space will be alleviated as the beta begins to exit "beta".
