My daughter has a 14 Pro and she says so many of her photos appear to initially be focused and fine but then the processing does its thing (the image goes very blurred for a moment) and then the end result is a blurry useless photo. It's gotten so bad she's now taking screenshots of the clear focuses preview image to save before processing messes it up. Have you seen any discussion about this specific issue?I called about a replacement, but it was going to take weeks and I wasn't going without a phone. They logged it as a "cosmetic imperfection" and only offered to repair it.
Supposedly, once I get some time, I can walk into an Apple Store and they'll replace it. As for the camera, there's some discussion on the Apple support boards that Apple is aware of the autofocusing issues and is working on a software fix.
I have a 14 Pro max and occasionally have this happen to me, but not to the extent my daughter is seeing it. I've seen it happen on my 13 Pro, too. I think it's a software issue but I'm not sure. This is not my area of expertise.
