Its fixed. Called Apple Support, and they were able to give me tips about how I could possibly do it. After about half an hour of stressful wiping, I managed to restore from a backup from yesterday at midnight, I wish I could've done the one before wiping, but iCloud was being, well, iCloud. Magically the camera started saving pictures again.
Uh, could you tip us too, so we can be spared the call to Apple support - not that it's in general bad, the support. Just easier to DIY.
Its all the apps connected to the camera for me. Hipstamatic, Camera+ and Camera. If I make a reset and star the phone again I can use these apps. But after some use - impossible. It's like ... when the get the photo back from iOS7, it happens. That's my feeling, anyway.
well I agree with jakob.joergensen but since the other guy did not tell you how to fix the issue I am going to tell you how first of all you have to hold the home button and power button untill a apple sign shows up on the screen. after that once the apple sign has disaperd you press the home button . finally your camera should be working.
