I often find that FaceID won’t unlock the first time it scand my face and the padlock stays closed, however, it doesn’t immediately try again and instead I have to press the sleep wake button to trigger FaceID to attempt a second scan.

Anybody elese notice this?
 
If it didn't recognize you (angle, lighting, etc) you are better off putting in the code and having it learn from the scan than forcing another scan with the button. It will help with recognition in the long run.

Ah really. Any reference to this? I’m tempted to force it to fail so I can improve it.

"To improve unlock performance and keep pace with the natural changes of your face and look, Face ID augments its stored mathematical representation over time. Upon successful unlock, Face ID may use the newly calculated mathematical representation—if its quality is sufficient—for a finite number of additional unlocks before that data is discarded. Conversely, if Face ID fails to recognize you, but the match quality is higher than a certain threshold and you immediately follow the failure by entering your passcode, Face ID takes another capture and augments its enrolled Face ID data with the newly calculated mathematical representation."

Initiate the second try by lowering the phone and raise again without sleep/reawake.

That sounds impressive and unbelievably sophisticated and makes me long for the days of Touch ID.

Rescan your face slowly and completely. Full circles. It doesn't sound like it is working correctly for you. Mine works 99% of the time. As good or better than Touch ID. Much better than Touch ID when logging into PW protected sites.

I’d say it’s on par with TouchID v1

If you enter your passcode after it fails it adjusts to recognize your face better.

The thing that doesn't work with AI is when humans think they know better and try to circumvent. Unless you are specifically hacking with an objective I really wouldn't do that. Just use your phone normally, and simply enter the PIN when requested and move on.

Mine works just fine in 40 Degrees Australian bright sunshine (wearing SPF hats and sunnies) as it does in -16 Polish cold nights (wearing very warm head gear) as it does in UK grey and wet January (wearing rain hats).

Eh?! What are you even talking about? Who’s hacking what?

No I did not at all. Perhaps you have missed the word Unless that was at the beginning of the sentence, or perhaps you don’t understand it’s meaning, or perhaps you are just looking for a stupid argument. You tell me what it is, I did not say any such thing.

Look, I have better things to do in life than going on a unfounded argument on forum. I’d rather not comment anymore.

Roflmao welcome to the 21st, rather than bowing out gracefully and admitting one got the wrong end of the stick it’s a case of I don’t talk to you anymore. Hilarious if it wasn’t so sad.

They were saying it’s not a good idea to make Face ID fail on purpose to try and get it to learn your face better. Which makes sense since the scenarios where it fails will be different and trying to recreate that wouldn’t be as accurate.

Though you’d have a hard time doing it anyway since Face ID has to recognize your face by a specific amount for it to save the data.

Yes my phone does it about 100 times a day. I hate Face ID with a passion. Should’ve been on the first iPhone. This is 2007 technology not 2018... Touch ID is definitely a upgrade to Face ID

Did you ever have your phone checked at the genius bar? I still think it has a problem. FaceID on my X is darn near perfect. The TouchID on my 6s and IPA2 are not nearly as accurate. Using RTW with FID on my X is like having a phone that doesn't lock.

Get it checked, that is not normal at all. I can count the number of retries during a week on one hand and then the pin entry is instant.

Failing that perhaps get a facelift :)

Yeah but Apple recommends that method anyway to help the algorithm learn changes. So trying it doesn’t harm because as you said, it has to match upto a certain percentage to begin with for it to adjust.

They never recommended to attempt to fail on purpose, at least I’ve never seen that mentioned anywhere. They simply mentioned that when it fails ended the pin. That is the process to let it learn from that fail.

We will put you down as a maybe for FaceID.

It should not be doing it 100 times a day as you said you no longer use it.

Well in another thread a guy said give it another shot. That maybe I didn’t set it up correctly so I tried it again. The main thing I hate about it is at angles.
