Is anyone experiencing times where Face ID just simply fail to detect your face? As in it doesn't detect a face in front of the camera at all, rather than failing to authenticate your face with its face data. I could swipe up to unlock my phone, and the locked paddock does nothing at all before defaulting to the number pad. It's not like it's failing to match my face, because the paddock would have at least jiggled then. When attempting to set up Face ID after I've reset it, the camera doesn't detect my face at all. It'll tell me to position my face in the frame, which I was already doing. I don't have bright light shining behind me, and my surroundings are not reflective at all. Do you think it's a problem with the TrueDepth camera/dot projector/IR sensor?
