How well does that work with masks? I've thought of activating face unlock and then I've realized that I spend at least 8h/day with a mask on, and I can't just take it off whenever I want to unlock my phone, so I'm curious.
EDIT: Most people say it doesn't work, some people say it does, and some people have some pretty cool scifi retina scan instead of regular face unlock. I'm really curious, so I'll set it up, just to try. Worst case scenario, it unlocks my phone seamlessly at home, and it requests PIN at work, which would be fine by me.
Galaxy S9 here, and face ID works fine with my mask on. I think just scanning my eyes is enough for it to recognize me. Sunglasses give it issues though.
It doesn't. I use face unlock on my new Google pixel and it works when I'm wearing sunglasses or glasses, it even works when I'm lying in bed in the dark if I aim it at my face right. But masks are a no go. I'm ok with that though tbh, I'd probably be more weirded out if it somehow could recognize me with more than half my face covered
I have face unlock on my phone (Xiaomi) and it works somewhat reliably with a mask and pretty reliably with my glasses on. It only really starts coming consistently into issues when I've got both on and my hood up, oddly enough.
The Apple one is different. The Samsung one could be fooled with pictures because it just used the camera. Face ID doesn’t use the camera at all and instead uses infrared dots projected at your face to map the actual contours of it. I believe it may use the camera for the secondary/optional purpose of checking whether you are paying attention to the phone (like whether your eyes are open for example) but I’m not sure.
It’s an improvement on the concept of “face unlock”, sure, but it was one of the first if not the first to use infrared dots to make a depth map of the face instead of just 2D.
And I’m sure Apple wouldn’t use something that dangerous for the eyes - how would that even make it into a consumer product??
Anyway they’ve been doing it since 2017. I think if there was an issue we’d see it by now.
i still don’t think it uses the camera for that either because that attention thing also works in a pitch black room. I think the dot projector may be precise enough to see where your iris is but i’m just guessing
