a bit of background: I got an iPhone X in December last year, and it had a bug where after an interval of between perhaps a couple of hours up to a day or two, Face ID would stop working. Turning the phone off and on again would make it work again until at random it would stop. I had figured that as a reboot made it work it was a software rather than hardware problem that at some point would get fixed. I stuck with it right through until iOS 12 came along and still no fix. I got annoyed and started searching, and found people suggesting it might be a hardware problem after all, so I was trying to find a gap in my schedule to make an appointment at my nearest Apple store. A little over a week ago overnight my phone did its thing and quietly updated to 12.1. Since then then Face ID has worked flawlessly for me. It’s now long enough that I’m beginning to think this might be the software fix I had finally given up hope of ever getting. Am I just having a lucky spell and the old problem will return, or is this a genuine fix? Does anyone else have any related experience?
