10.3.2 beta iPhone 7+ Since the most recent update I have noticed terrible auto-focus performance under low light conditions. Often I notice the focus lock, and before I can release the shutter, the camera begins wildly searching the far ends of the focus range before settling on a very out of focus photo. Daylight photos have been fine. Photos from 2 recent concerts and a party have been 75% garbage. Anyone else noticing this?
