GUYS GUYS GUYS, I have 100% figured out the issue. This is a sad TRUTH to the issue. This is a hardware issue, which I don’t know for sure if can be fixed with software updates! Everyone that has this problem. The flashlight is the perfect test. It either works with your thumb perfectly on and off flawlessly or doesn’t. The reason it works with the case off is because for whatever reason, every single Case that goes on the iPhone 12 mini or the iPhone 12 mini power button doesn’t have the proper support to stay UN-PRESSED, while the cases’ push button sits next to power button. The side power button on right hand side is being pressed a small amount with every single case!
WATCH, put your finger and push against case only where side power button is and push case away from power side button and watch how easy the flashlight works with your thicker thumb, thinner thumb whatever. It’s the POWER button that’s being pressed lightly by all cases causing this issue!!!
APPLE THIS IS 100% confirmed. TIME FOR RECALL!!!!!
