Hello ShannonBSN,
Thanks for posting in the Apple Support Communities. We're happy to look into this with you.
We appreciate you providing us with details about the issue with your camera and the steps you've tried up to this point. We recommend trying the suggestions provided in article, If the camera or flash on your iPhone, iPad, or iPod touch isn't working - Apple Support.
If your photos are blurry or the camera screen is black, here's what to do.
Remove case, accessory, or film and test
1. Remove any case, accessory, or film that might block the camera or flash or that places a magnet near the camera.
2. Test the camera by trying to take a photo.
3. Test the LED flash:
4. Try the flashlight in Control Center on your iPhone or Control Center on your iPad. On an iPhone X or later or an iPad, swipe down from the upper-right corner of the screen. On an iPhone 8 or earlier, swipe up from the bottom edge of any screen.
5. Tap the Flashlight button
.
If the flash works only sometimes, open the Camera app and tap the flash button
to choose a different setting.
It's also a good idea to test and see if the issue persists in 3rd party camera apps as well. This can help determine if the issue is the camera itself or the software. Should you find the issue persists after the actions above and in 3rd party apps, contacting Apple Support at Get Support or having the iPhone inspected would be your best option.
