Face ID has issues in the dark

[cheekyjeremy]

any less than 50% brightness and neither my wife of myself can get Face ID to work in the dark. This is on two different phones. The downside is that when scrolling in bed, the brightness needs to be more or less all the way up to unlock. Not conducive to a relaxing experience. Seems to be slightly less of an issue when standing than laying down, but only slightly.

Otherwise, love the phone

That's odd. It's supposed to work in the dark. Even in pitch black...

What does screen brightness have to do with Face ID? Mine works better in the dark, hasn't failed once yet.

He means that the brightness on the phone makes it so that light is shining on his face.

Mine hasn't failed either. Works at lowest brightness in pitch black. I'm actually amazed.

I was assuming that seeing as Face ID worked at full screen brightness and stopped working at about 70% brightness, that maybe it’s being helped by the fact that the screen is illuminating our faces when we look at it. Whatever the case, this is the scenario we have at the moment.

Face ID works via infrared, if anything it should work better in the dark.

that happened to me. I decided to try redoing my FaceID with all the lights off. Now it works perfectly in a bright or dark room.

 

[cheekyjeremy]

Definitely doesn’t work (for us) at the lower brightness levels. I’ll rescan my face again tomorrow during day and see if it makes a difference.

It didn't for me either.

 

[allthingsapple!]

i stood in my bathroom and turned the lights off so it was pitch black and my phone worked perfectly fine every time.

 

[Aussi3]

Works perfectly fine for me I did it pitch black last night worked perfectly fine

 

[cheekyjeremy]

Certainly seems to work much better when standing than when laying down.

 

[Bagio]

not had any problems here

 

[cheekyjeremy]

and now it seems to work fine. Maybe I picked the wrong day to quit sniffing glue

i don't think the screen brightness has anything to do with it.

for example.. just turned my brightness all the way down.. then additionally covered the display except for the cameras..
made the room completely dark..

faceID worked fine

?

[edit] just saw your post right above mine so...
nevermind

I may have had the issue because when I did FaceID the phone was a bit too close to my face and probably did not get all of my head. So I held my arm further out, did the scan where my entire head was in the image finder. Works much better now in both light and dark.

thats odd it works for me in a completely lightless room

also you might want to do the 2 Profile Trick

I also heard that iOS 11.1 was supposed to fix faceID issues. If you haven't updated, give that a try.

Whats the 2 profile trick?

 

[hasanahmad]

Whats the 2 profile trick?

when setting up face ID it asks you to scan your face twice. first time do it with camera in front, second time do it with camera below your face as if you are looking down on it.

Im gonna take a wild guess here and say that you can try registering two faces when FaceID asks for two scans of your face. I have not tried this but would be interesting.
