FaceID missing 80% of the time

[macsrcool1234]

Can someone give tips on optimal setup for faceid? It's extremely frustrating how often faceid is failing to recognize me. i've redone setup like 10 times already.

the biggest problem seems to be it only works in the conditions i did the original setup. These are some of the things that make it start missing nearly all of the time:

1. Putting on glasses
2. Laying down
3. Different lighting conditions (it has yet to work in any kind of dim light darkness at all)

im really starting to wonder how many real world scenarios Apple tested in

i am not seeing similar experience on the internet.....what am i doing wrong?

Mine had issues with my glasses on as well. Works seamlessly with out glasses on and even with dim lighting.

Mine is flaky. I assume it’ll improve. Touch ID was flaky on the 5s.

Mine works in all the scenarios you listed, including pitch black.

I think you have a lemon, or you may need to figure out a different distance. How close/far away are you holding it? 10-20 inches is what Apple says is optimal.

Also, did you turn off the attention requirement?

Mine has been absolutely flawless. With and without glasses and with and without a hat. So perfect in fact that I don't even think about it. It has already just become this automatic thing that happens when I pick up my phone.

Bring it back. It’s a lemon. Sh*t is Flawless. I haven’t had any problems. Outside,in dark room,laying down,glasses off and on. Works so fast I just swipe up and it is unlocked. Do a hard reset. Press volume up. Then volume down. Then hold down the power button for 10 seconds. If that don’t work. Bring it back.

Mine is working flawlessly as well in a variety of lights and even angles. I know you said you re-did the setup about 10 times but, I want to ask if you rotated your head quickly or slowly during the setup process. I also held my phone on a table in front of me so it scanned my face more from the bottom.

Mine has been flawless except when it's on my desk because it can't see me. Also keeping 1 eye closed it still opens.

When doing FaceID, I set mine up with my glasses off. Then get all of your head in the viewfinder and rotate 3 dimensionally. IOW, just dont rotate your head in a circle, also move it up/down left and right as you are rotating your head in a circle.

Mine works perfect with glasses. It works in all situations

 

[mazdamiata210]

Redo your face, and go slow... I went really slow in low light

 

[Hoosier317]

Redo your face

Wow...now that's harsh....

 

[mazdamiata210]

Wow...now that's harsh....

Whoops lol

Dunno what’s wrong with your phone, but mine’s been flawless as well, even under conditions people were afraid of previously. See my post from this morning after I got my X:

My wife’s was way slower than mine and way less consistent. She was holding phone closer to her face and rotating her head super quick when she set it up. She redid setup further back (arm almost fully extended) and moved her head slower. Now it works super fast and at all angles for her.

Mine works good all the time I thought it might have troubles with polarized sunglasses but nope it’s been awesome!

That's the key. People think it's taking a "picture" of their face, when it's actually trying to create a 3D rendering, so it needs the head to be moving in all directions.

Does Face ID use ambient light, or IR projected dots?

 

[bkrbyndr]

Mine works great!

 

[Packers1958]

IR. You could do it in a totally dark room, and it will still create a 3D image of your face.

You have great luck. Never any issues.

IR dots, but I would imagine if you set it up in a super bright area it would be less accurate than doing it in a dark room

Mine is working mind blowingly well.

 

[irobots]

No issues. Even unlocks in the dark. Was watching previews in the movie theatre and I took my phone out of my pocket and unlocks like a charm.

what am i doing wrong?

hard to say tbh because it really does work incredibly well.. i mean, i know (most) everybody else is saying similar but i think that's because it's true and not some sort of denial phase.

two things i suppose i'd recommend..

• update to iOS 11.1 (not actually sure if this will help but i'll recommend regardless)

• when it fails to unlock, enter your passcode instead of sleeping the phone and trying again.. my understanding is that it will learn as you go along and the passcode is what's telling it that you're there and to remember the failed ID as being one that should be correct..
