Well i sort of have a solution for this.
Just download the app Snapchat, for some reason this app doesn't make the camera force close since it uses it's own.
It's not the best but in order to do this:
1.Go to the camera on there
2.Just screenshot the screen.
Until there is an OTA update or you plan on getting a replacement, this is the only solution i have figured out so far.
If i helped any please press thanks. 👍
