I’ve been experiencing this issue since the iPhone 12 or earlier. When I open the Photos or Camera app, the live camera preview appears but then freezes, and the controls become unresponsive. I have to force-close the app and reopen it. It happens about once every 10 times, but it’s been a persistent problem over the years. I’ve had the iPhone X, 12, 14, 15, and now 16, and it’s especially frustrating when I need to take a quick photo. Does anyone know what’s causing this? Would a clean iOS install help? I had this happen today and noticed i was on low power mode maybe that might be a clue even though it happens even when I have low power mode off.
