Internet, with this forum no exception, is awash with praise for the phenomenal Face ID, and I have no doubt that it is for good reason. But I stand with quivering lower lip, struggling to make it work on my own shiny new X. What I don’t find anywhere is: why the fails? What makes Face ID fail some users? Should one give up and take the unit back, is there something wrong with my TrueDepth system? I’ve set, reset and set up Face ID many, many times, reboots aplenty, unit resets, a wide variety of approaches to the face scanning process, low light, bright light, slowly turning my head, even more slowly turning my head, clockwise, counter, at a distance, at short range, in between … it is still slow at best, failing miserably at worst. What am I and the other few misfortunates doing wrong? Is it a device fault or a face fault? There have been a few threads on this, but they are usually quickly paved with happy posts from satisfied X owners. Suggestions?
