My IPhone 12 screen often goes black when trying to open active call
Often when I am in an active call, or meeting, but my phone is on the home screen, when I press the small green button for the call at the upper-left, my screen will go black, and then back to the home screen. I haven't figured out the circumstances where the call will eventually open, but sometimes it takes numerous clicks to get the call open. Its quite frustrating
