Ok so I have a 128gb iPhone 6s; yesterday I was using 32 gb of storage and now I'm using 111 gb. I haven't downloaded anything large recently. I've tried restarting the phone, syncing through iTunes, and restoring from a backup. In iTunes its showing that new space as being used up by Documents and Data. I don't watch movies on my phone and don't do many things with documents that would be that large. How can I figure what is in my documents and data section that could be so large? Or how can I get that free space back?
