Nah, it shouldn't be possible in the first place to develop an app that physically breaks the camera. Something is wrong at the hardware, software, API, firmware, or driver level causing this. Third party app devs are not to blame here.
Since it's social media apps that seem to be doing it, they're probably all using a certain API call that is triggering the camera to spaz out - an API that is developed and provided by Apple.
The real questions are:
1. Can this be fixed by an iOS update? And if not, oh boy do we have a big replacement program on our hands.
2. Are they going to replace each phone that exhibits this issue? It seems from early reports that once the camera has jiggled around, it has likely suffered permanent damage.
3. How widespread the issue is.
4. What caused it?
