    Hey all,

    Just curious - do the lighting conditions matter? Couldn't find any information on that.

    Does it make any difference if I set it up when it's dark using artificial lighting, or throughout the day using daylight? Can anyone chime in and share what's the optimal scenario?

    Thanks in advance!

    Follow the advice of Nike. Just Do It.

    Lighting conditions don’t matter, since it doesn’t rely on ambient light.

    The only time light matters is if you’re standing with your phone in direct sunlight shining over your shoulder into the sensor. Then, it sometimes takes me repositioning slightly to unlock.

    As for advice setting it up, I recommend you turn your head as far up, down, and to the side as possible. That helps me get all the possible positions I’ll be in for an unlock. Like, with a double chin, looking down, slightly slanted, etc.

    My Face ID works incredibly well; I almost never have to reposition or have it rejected.

    ^^ What was said above. Regular room lighting will do just fine. Just follow the instructions and it will work flawlessly.

    Add an alternative face ID profile for when you wake up in the morning and still in bed :)

    My other piece of advice would be: actually use your face. Setting up ButtID is a pain in the... heh, a pain in the rear.

    Trying to get the mirror placement to figure out how to wiggle your posterior for its detection to work is a pain in the... wait, I already did that one.

    My advice would be to turn off face attention setting.
    FaceID works much better and faster.

    Yes you can have two face ID profiles. I bought my girlfriend an XR and she set it up initially in bed, didnt work well for face ID while not in bed and at the same time I was having perfect face ID experience on my XS max while not in bed but would not work while I was in bed. So advised her to set up a 2nd one while not in bed and I set one up while in bed... fixed both of our problems :)
