Greetings, I have recently come across an issue that is driving me up the wall. Firstly, I will mention I have an iPhone 4s, 64GB and iTunes Match so there is no music, videos, or anything of significant size on my iPhone. What has been giving me issues is that for some reason all of the space on my device is taken up. At first I thought maybe I had downloaded music from iTunes Match and that I just needed to clear it. But that wasn't the case. I then plugged my device into the computer and opened iTunes to discover that 51.72 GB worth of space is taken up by "Other". I have attached an image of iTunes displaying this. I tried to find out what "other" space really is and I am certain there is no way that much space is taken up by data files by apps I don't even use such as Mail, etc. Does anyone have any advice to fix this without restoring my iPhone? I don't want to upgrade (in this case downgrade) to iOS 8 on my device because I know how much it will slow the phone down. I have also tried going into settings and clearing all content and settings, etc. No luck.
