That's a good point, I don't see it as much of a sticking point. And why revert back to Touch ID if Face ID works well? Just improve upon Face ID.
Exactly. Also FaceID is now a marketing tool. It's a name people associate with iPhone now and will continue into the future. If apple did implement touch id again it is taking a step back and inhabiting internal real estate in the phone.

I'd love to know how many people here complaining about the problems with FaceID (and how in-display TouchID would be better) actually own the iPhone X.

My guess is none.

My experience with Touch ID was so different from many people, it seems. It was so inconsistent for me, along with the "forgetting" effect, that I disabled it. I would turn it back on with each OS update to try, but it was no good.

Face ID has been a completely different story. It has worked quickly and perfectly for me. It has worked 100% of the time whenever it was supposed to work. It would fail only in cases where I knew it was not supposed to work, as in when I was looking away.

I believe those who say that they have issues with Face ID, although I do not understand why, like how it is inconceivable to some people that I had so much trouble with Touch ID. However, I also think that many of these people simply do not know how it works. They are biased against it to begin with, and then get super frustrated at the first sign of trouble.

If Apple was lying to us about not investing in fingerprint tech and we find it in next year's iPhone X successor, I will be sorely disappointed in Apple...

Unfortunately, Apple says what it needs to at the time in order to sell its wares. It should come as no surprise when/if Apple changes its mind - on anything it says. It's part of living in the Apple universe.

I bet you're 99% correct.

I had my doubt at first, but after using the X, I really don't want to go back to using TouchID anymore. Unlocking my phone with FaceID is so much more seamless and intuitive now.

With all this talk about under-the-display fingerprint sensors, I wonder if it'd still work with a cracked display.

Since upcoming phones will most likely have edge-to-edge displays, a cracked display might just render the fingerprint module useless.
This could also cause face ID to stop working.
 
Back when people thought Apple was doing an in-display fingerprint sensor, it was thought from their patents that it might be image based as well.



An RF signal from the sensor ring passes through your fingertip and is measured by a tiny antenna array in the center part. This gives a 3D image of the fingerprint's ridges, valleys and pores.

Which is why a 3D copy works as well. It's also why a wet finger fails, as that provides a short cicuit signal path across the finger surface instead of having to pass internally.



Synaptics' device includes its own encryption and secure processor.



No, that was a fan myth.



Their security white papers talk generically about looking for temperature, pulse, flexing, etc, but do not give info about the actual methods used in this sensor, other than claiming that they use an AI based scheme which rejects 99% of spoof attempts.

This claim will be tested quickly, no doubt!

I was an early supporter of FaceId, and it's still a good method. However, its sensors takes up frontal space.

So I can easily see under-screen print sensors being popular on phones where the front is used for a notchless display.
Thanks for the in depth reply! Very informative!
 
And I had started to believe the Android phone makers that fingerprint sensor on the back is a great ergonomic solution, if one believed them then there would be no development for fingerprint sensors under the screen.

Makes the job easy for the ones disappointed with Apple to switch.

Don’t see the point. If you have to look for and place your finger in a specific spot, by then your phone would already be unlocked with Face ID. Without some sort of indentation to feel for, you’d have to pay attention each time.
No you won't. It becomes muscle memory. Just like how holding your phone the correct way to get face ID working at its most optimal distance and angle.

My current Android phone has capacitive buttons that I turned the lights off so I can't see them. However I definitely know where to place my finger.

Just like rear finger print sensors. Yes, they have indentations, but I don't go feeling for them, I know exactly where it is without looking.

Have you had a chance to use Face ID for a few days?
[doublepost=1513170867][/doublepost]

How so?
Correct me if I'm wrong, but isn't all the sensors for face ID under the front glass? I would think there is a possibility if the glass is cracked around the sensors it would cause issues for them scanning your face.

I don't know, I would still imagine you needing you to look at your phone to do this. At that point, your phone would already be unlocked. Either way, Apple will just continue to improve upon Face ID which already works really well. No reason to revert back to Touch ID.
 
And I had started to believe the Android phone makers that fingerprint sensor on the back is a great ergonomic solution, if one believed them then there would be no development for fingerprint sensors under the screen.

If one believed Apple about TouchId and Home buttons, then there'd have been no FaceId and full screen development.

Technology progresses. More choices appear. Doesn't make previous choices bad. They were just subject to the limits of the time.

Well if I can use this under the screen finger print sensors like my pass 2 phones...my phone is unlocked before I even finish taking it out of my pocket. When I reach for my phone in my pocket, my finger automatically goes to the FP sensor without thinking. By time I have it in front of me it'd already unlocked. Compared to face ID I have to pull it out of my pocket and look at it then wait the 1 second for it to unlock.

Question, when you're using your X, do you have to look at the white bar at the bottom to use it? (whatever apple calls it).
 
Neither TouchID or FaceID is perfect. However, I find FaceID the better all-round solution and is faster overall than TouchID.

Putting a fingerprint sensor under the screen doesn’t change any of that. It also doesn’t get rid of the notch (unless you don’t want a front camera, proximity sensor or speaker). So you still have to choose between a bezel or a notch.
 
Rumours say this is the Galaxy S9. They have been working closely with Samsung for a few years apparently. Now wouldn’t that be an interesting battle? iPhone X with Face ID and Galaxy S9 with under screen finger print scanner.
 
Surprised no one has asked if it will come with a key logger driver. ;) To stay on topic though I am really enjoying FaceID, especially for app authentication. As soon as it loads I'm authenticated and using the application I launched.

I guess if you can know exactly where your finger is on your screen with it in your pocket, sure. No, I don't look at the bottom bar because you don't have to press it. This, presumably, you would. Either way, really no reason to go back and forth about it. Apple has been clear that Face ID is the future. History and common sense would say Touch ID isn't coming back.
 
Can't wait for both FaceID and TouchID on the same device. Don't tell the iPhone X users; they will tell you TouchID is no longer wanted.
 
Synaptics' device includes its own encryption and secure processor.

“Includes its own encryption and secure processor.” Meaning it’s going to be a more expensive component. Apple has the advantage of designing their silicon to work with their sensors, allowing their A Series to do the heavy lifting. The way I see it Synaptics has three choices: expensive sensor with high-performance processing, cheap sensor with basic processing, or a compromise of the two.

Sensor size is another issue. If the sensor is small (like the Home button), then you have a very small target area on the screen that will work. This makes the chance of hitting it by “muscle memory” much lower. A large sensor would significantly reduce this problem, but then increase the costs. So again there will be a compromise between cost and ease of use.

Finally, what does “99% of spoof attempts” even mean? Sound like marketing mumbo-jumbo to me.

So I can easily see under-screen print sensors being popular on phones where the front is used for a notchless display.

Front facing cameras, proximity sensors and speakers also take up front space. An under the screen fingerprint sensor doesn’t eliminate this. It only eliminates the bottom bezel (for a front sensor).

Don't worry they'll still incorporate two fingerprint scanners on the back of the phone and one on the side button

Synaptic's PR documents claim the difference is about 25 cents between what they call a cheap mobile sensor, and their encrypted sensor.

True, but see previous response about haptics.

lol I know. It's like Apple saying they worked with Hollywood mask makers to try to make FaceId less subject to spoofs. It doesn't mean they actually prevented such spoofs.

Front facing cameras, proximity sensors and speakers also take up front space. An under the screen fingerprint sensor doesn’t eliminate this. It only eliminates the bottom bezel (for a front sensor).

Valid point. Although some of that has already been embedded in or under displays.

So what's the big difference between pressing and swiping? Your finger has to be on the right spot of the screen to do either correct?

So if you don't have to look on the bottom bar to use your X, why do you think you have to look on the bottom of the screen to use the finger print sensor? Your logic is flawed and that makes no sense. Is either you agree to both that you don't have to look or you agree to both that you have to look.

I wasn't debating if Apple is bringing back touch ID.

However just like when Face ID was announced before the X was released, many was defending Apple that people should wait to use it before making judgement. Now the tables are flipped and you're already assuming and saying FaceID will be better without even using touch ID under the glass. Why not wait to use it before making judgement.

(general statement below not aimed at you)
The hypocrisy is strong in this thread. Many defenders of Face ID before the X was released argued with others that they haven't even used it so they can't claim Face ID is not as good as touch ID.

Now the tables are flipped and these same people are passing judgement on something they haven't used.

When Apple does it they defend and defend. Once another manufacturer does it, they discredit it without using it.

I was just commenting on the ergonomics of a back fingerprint sensor on phones, if it supposedly were a good choice, under the screen sensor development would not be necessary. Now the development for such a sensor is underway, it only means the ergonomics of the back fingerprint sensor were compromised.

I still remember the days when most Android phones had speakers on the back, which slowly evolved to be placed on the front or the bottom.

Another example of good ergonomic choice of Apple from the outset. Not that all Apple ergonomic choices are great, but these examples stick out to me.
