> Let’s say I get a text, my phone is on the night stand. I just look at it and it already unlocks, no reaching.
My phone is on the table while I'm working. In order for it to see my face I have to pick it up and aim it at my face. With touch id I could just put my finger on top without having to pick it up. So much faster and more convenient.
I find that quite often face id is slow or fails, even if it only fails one out of 30 times that's still one a day and when it does it's frustrating as hell. Something that should take 0.5 seconds ends up taking 10-15. I know that sounds trivial but by the time the phone has unlocked, whatever I was planning to do is often forgotten because of the distraction of trying to get face id to work and then having to manually unlock.
And of course now with mask wearing it basically might as well not exist.
With a fingerprint sensor, the only time my phone would have any trouble unlocking would be if my finger was wet (trivial to fix and re-swipe). Face unlock fails all the time for all sorts of reasons, and is especially useless when I have a mask on (it's nice of Apple to detect masks and bring up the PIN pad without needing an extra swipe, but that's still a weak workaround). Even without a mask, I feel like the failure rate approaches 1% to 2%, which is way too much. For me to feel comfortable using it, I expect something on the order of 0.01%.
Actually I'm not even sure it's the failure rate that gets me. Even after using face unlock for the better part of a year, I still catch myself looking at the phone thinking it's waiting for my face when it isn't, and then I have to swipe up or hit the power button or something. Yes, maybe you can call these UX problems that can be fixed with software, but with a fingerprint sensor I know that when I touch it, my phone will vibrate, and I know immediately if it succeeded or failed.
I think also part of the difference is that Pixel phones have had their fingerprint sensor on the back instead of the front, like iPhones used to have. If the phone is just lying face-up on a table (and I don't want to pick it up), then having it on the front is much easier. But, in reality, I found that was rarely the case for me; usually it'd be in my pocket, or even if it was on a table, I'd want to pick it up anyway. The act of wrapping my hand around the phone would put a finger in roughly the right position to hit the sensor anyway, so it'd be unlocked and ready to use well before I was in a position to read anything off the screen anyway.
Frankly I just really don't like face unlock when compared to a fingerprint sensor.
1. Phone standby to phone on (as you describe)
2. In-phone software actions, typically, password manager or locked/private apps (banking, etc)
For case #2, I greatly prefer FaceID. For case #1, it’s a toss up for me.
Why did I miss it? Because FaceID will unlock the notification area and its associated actions before I perform any action or even touch the phone.
Let’s say I get a text, my phone is on the night stand. I just look at it and it already unlocks, no reaching.
It lets you skip a step and start interacting with the screen before the phone has unlocked. Perhaps less of a big deal with the back-mounted fingerprint sensor, in that case I could interact with the thumb simultaneous to unlocking the back.
Using password managers was another big one. Instead of tapping the auto fill button, then tapping the fingerprint sensor, it was all one click. Opening bank apps, same thing. FaceID is always one less finger motion.
Mask wearing has thrown a wrench into it but Apple has added logic to quickly bring up the pin pad when it detects a face mask. Also, sometimes it seems to learn my masked face, but that’s less reliable.
I don’t know how this compares to Pixel face unlocking at all, admittedly.
And I never understood why Apple didn’t use the rear mounted fingerprint sensor. But I do understand why they think the benefits of face unlocking outweigh the drawbacks.
Some examples not related to the action of unlocking: when your alarm goes off, the noise gets quiet when you look at the phone. Also, the screen won’t time out and turn off while your eyes are looking at it.
