Constant Infrared flashing
I’ve seen this question come and go a few times- but recently noticed while reviewing security footage that all recent iPhones do emit bright IR flashes, roughly every 10-15 seconds, directly at the users face. I’ve started to pay more attention to this and tried disabling face-ID, which does not stop it. Why are all iPhones flashing bright (but invisible to most humans) infrared light at us thousands of times every day. Is it required for Face ID (but impossible to disable)?
Bottom line, whether you realize it or not (or want to admit it), this IS happening to you too- right now. All day, every day. What exactly is the purpose and why can I not disable it, if I so desire?
