iPhone 12 Pro Max .5 only works in videos

Hi augusta113,

Thanks for reaching out to Apple Support Communities.

It sounds like you’re having an issue with the camera on your iPhone.

We’re happy to assist.

We recommend checking out the steps in the link here: If the camera or flash on your iPhone, iPad, or iPod touch isn't working

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:

1. 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.

2.Tap the Flashlight button .

If the flash works only sometimes, open the Camera app and tap the flash button  to choose a different setting.

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 .

The reason why we’re recommending the steps above is because they directly address the issue you initially posted about: the camera on your iPhone isn't working as expected.

Should the issue continue, check to see if your device needs to be updated: Update your iPhone or iPad

Please do not hesitate to reach back out to us if you have more questions.

Cheers!
