-1 missed calls, and disappearing apps
So today my iPhone 7 has started acting really strange.
At one point, I turned it on after it charged, and 4/5 home screen pages with apps on them were completely blank, and the app bar at the bottom of the screen was also blank. The apps were actually still there, I was able to tap on them despite them being "invisible" and showed the red notification bubbles from some apps. I attempted to restart and that seemed to fix the issue for now, however now, many apps are freezing heavily or completely crashing on startup.
I then got a call and went to pick it up, but the phone buzzed for a slit second and stopped, and nothing came up on the screen. When I unlocked it to check who called me and so I could call the person back, the contacts app had a -1 icon for missed calls, and freezes on startup.
I also am unable to delete any photos or videos, they "delete" and then pop right back up in the camera roll. I also cant connect the phone to my PC to download my photos from it in case I can't fix it, keeps giving me an error.
Bizarre, never had an iPhone behave on me this way.
