Hello confused_2020,
Thank you for reaching out in Apple Support Communities. I understand you're unable to automatically focus in on images with the camera feature on your iPhone.
Capturing your most memorable moments is important and I'd like to help.
Excellent job with the troubleshooting steps that were performed. Are you experiencing this behavior with a third party app or through the Camera app on your iPhone? If it's with a third party app on your iPhone, I suggest following the steps outlined here: If an app unexpectedly quits, stops responding, or won’t open
In addition, I recommend having the latest iOS version on your iPhone. This helps provide software improvements on your device: Update your iPhone, iPad, or iPod touch
Please keep us posted with the results.
Cheers.
