I didn't even use the iphone 12 pro max which just bought from the Apple store, and after updating iOS to 14.7.1 this **** “important camera message” appeared. After that:
flash is not working, neither in the camera app nor from the control center,
sometimes the camera app is black, sometimes there is video, but you can't zoom out to ultra-wide or tele zoom in
Buttons often get stuck in the camera app.
So, I paid to Apple for an expensive phone because of a good camera and only got a charging cable and a cell phone without a camera, and support only advises replacing the camera which was sold broken to me. Not fair. Very disappointed.
