I tried to update my face id hoping that it will become faster... but didn't work.

I'm pretty new to iPhones so is there an option to downgrade from 12.1 to 12.0.1?
I found some articles on google but is it safe to do it? Any feedback would be much appreciated
 
What impressed me was that face ID used to work when lying down in bed. Face on the pillow. Since 12.1 it will now only work when full face is in view.

Seems to be a touch more sensitive. Maybe they messed up before and it was less secure.

I urge all those with issues to submit a bug report. Without this APPLE WILL DO NOTHING!

Do so here: https://developer.apple.com/bug-reporting/

Paste the following as your problem;

Summary:
Since updating to 12.1 my iPhone XS has been noticible slower to authenticate via face ID than it was with 12.0.1

Steps to Reproduce:
Attempt to unlock screen by swiping up.

Expected Results:
When swiping up unlocking used to occur on 12.0.1 before the unlock animation completed.

Actual Results:
Now unlocking will only occur after the unlock animation has completed.

Version/Build:
12.1 (16B92)

Configuration:
Happens with a freshly resorted device setup as new or restored from a backup. Also same result if settings reset or face ID reconfigured.

Just did this. I've also just downgraded back to 12.0.1 and I'm really happy I did so! Face ID works like a charm again! =)
 
It now also struggles to recognise me in my sunglasses. I have mirrored ray bans which don't work with attention awareness so that's off. No alternate appearance. I may have to set that up.
 
It is most likely a bug, since they probably merged code for FaceID on iPad as they released 12.1, and could get resolved in next iteration. Or maybe a more secure recognition in form of a more sure recognition and that takes time. At worst, it was a case of animation delay being introduced. I'm always surprised how for the smallest of software issues we think to go get an entire device replaced.

Update: I updated back to 12.1 using iTunes and it seems the issue has gone away for me. Face ID works the exact same way as it did on 12.0.1 now. Didn’t really do anything differently other than using iTunes instead of OTA to update. =)

Is this still working for you?

Might try an iTunes restore and see if that fixes it.

Just did a DFU restore and the results are the same. Starts off fast but after an hour its back to being hit and miss.

Can anyone else confirm that this has been fixed? I downgraded back to 12.0.1 because of the face id issues, but I've been having super annoying connection issues recently that will probably be resolved with an update.

Well, if anyone else is wondering, I'm on 12.1.2 now and it appears to be just as fast as 12.0.1.
