Horrendous Apple iPhone Pro 16 camera hardware or software problem. I picked up the iPhone on Sunday, 21 September. Within two days, the camera app was crashing intermittently. And once it started crashing (push button on screen or frame, the screen goes black momentarily then dumps me back onto home screen) it will continue to crash until you do a reset on the phone. I got Apple support on the phone and, after trying to help me, the agent said 'here's a genius bar reservation' (for Monday, 30 September.)
At the genius bar, they said yup, we'll take in your new, defective 512gig mem iPhone Pro and give you a new phone (as I had originally ordered.)
It took me until last night (1 October, to pretty much have everything up and running on my NEW phone) then the d**n camera problem started crashing again!!! This suggests this is not a rare defect! There are currently 55 replies re this problem.
