Hello Just1nLu3as,
Thank you for using Apple Support Communities and thank you for sharing this photo with us. We can clearly see that there is some sort of image quality issues going on here. It's good to know that you're also fully updated on your iOS version. We'd like to recommend a couple of helpful steps to see if we can get this issue sorted out or to possibly further isolate this issue. Let's start by following the steps below:
1.) Close the Camera app to help refresh things.
2.) Follow the steps listed here: 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 you want to try more steps on your own
If you prefer, here are some more steps you can try on your own if the camera isn't working. You might still need to contact Apple Support after following these steps.
1. If the photo is blurry, clean the front and back camera lenses with a microfiber cloth. If you see dirt or debris inside the lens or if the camera lens appears to be misaligned or blocked, contact Apple Support to discuss service options.
2. Restart your iPhone, iPad, or iPod touch.
3. Test the camera again by taking a photo. If your device has a front and rear camera, check if one or both isn’t working. To switch cameras, tap the rotate button .
If these steps don't help out, follow the guidance listed in the resource we shared and contact Apple Support for help. They might need to investigate this issue further with you. Use this link to contact them: Get Support
