Hey there, emma_young1x.

We see that you joined us through the If the camera or flash on your iPhone, iPad, or iPod touch isn't working page, which is a great one to use if you're seeing the issue that you've described. If the steps on that page didn't help, you may be experiencing an issue of a hardware nature, which means that the next step would be either an inspection from a service technician or service.
