Ive realised that my apps and system is taking up almost 90GB on my phone. When I click onto to see what taking up so much space only a few apps and system things seems to add up to a few GB. Both the app and storage have the (!) next to them. Any help would be great as I'm at a lose!
@LostinTech: If you tap the 'i' symbol to the right of Apps and System, then a pop-up will appear at the bottom of the screen which reads "To see how much space this item is using, turn on Usage data access for My Files in Settings." Tap on 'Settings', then toggle on 'My Files' from the Usage data access menu.
Now, head back to the Storage screen, and this will allow you to view a comprehensive breakdown of your app and system storage by tapping on each category. I hope this helps.
