16.4 update

Hello PureChlorine,

We understand your iPhone has some issues after the latest iOS update. Let's work through some steps that could help. We'll be referencing this article: If the camera or flash on your iPhone, iPad, or iPod touch isn't working - Apple Support

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.
