I have an iPhone 6. I updated to iOS10 when it came out and had no problems. I applied the iOS 10.2 update - for a minute there I thought it had bricked my phone, but was able to get it working - and now have the strangest camera problem:

If I open the camera app, the screen is black and it won't let me take a picture (tried normal, square). I tried both forward and rear facing cameras, neither works.

If I try using a 3rd party like Instagram, the app crashes.

What works:

Panoramic WORKS.

Video or slo-mo option front and rear cameras work

If I open iMessage and use the photo icon from there it lets me take a picture (front or back camera).

What I have tried:

1) Kill and restart the Camera app.

2) Hard restart (Hold down home and power button for long time)

3) Restart, then open the camera app from the lock screen. (tried various ways - with and without the flash on)

4) Toggle camera setting in restrictions. (also disable restrictions)

5) reset to factory settings (Settings -> General -> Reset -> Reset All Settings)

Any other suggestions? I'm ready to just wipe and restore at this point.
