Am I going mental, or does the number in the following image make no sense at all? my top 10 apps seem to account for barely ~15GB, so why is my used space so high?
So, I'm calling this a bug. The "other" section of my phone is taking up 40GB of space. I figured I'd just take a backup and restore my phone but due to there being no available space, I couldn't take a backup through iTunes. So I deleted my Spotify music, and the 40GB "other" grew almost instantly to take up the remainder of the space. I tried putting my phone into airplane more, but the button didn't put it into airplane mode - I had to restart and do it (I also temporarily lost use of my lock button and home button). I used a 3rd party tool to take a backup and deleted all my photos, and the storage has stopped growing at 42GB. Here's my iTunes screenshot for giggles:
I tried updating my iOS, nothing. I checked using iMazing at my phones directory structure (it allows you to view folder sizes) and none of my folders had 40GB, the total amounted to what my phone was reporting (~15GB).
I have no idea why it's doing it, so I'm going to go for a full restore from my newly created backup.
