Let me do it again.

So, as you know, I've been using the galaxy s 10 as my main device for a period of time now and I've given up on the face unlock.

I knew it wasn't very secure, but then I made that video showing just how easily fooled it was.

I played a video.

Unlock the device.

I'm just not using face on lock anymore, Not the way that it's implemented on the galaxy s 10.

But that's not all bad, because, of course, this device has that really cool ultrasonic fingerprint scanner underneath the display of the phone now in the face unlock hack video, I explain that I wasn't so happy.

I wasn't enjoying the in display fingerprint reader very much.

It just wasn't performing as I kind of wanted it to.

And so I gave it some thought.

I was like, Maybe there's a way to improve this.

Maybe I can register the same finger Maur than once I was thinking to myself, Wait, I just came from the one plus 60 and that didn't work.

And typically with e in display optical based fingerprint scanners, they won't allow you to register the same fingerprint more than once.

So, for example, Okay, on the right hand side here with one plus 60 you can see two fingerprints are registered.

Left thumb, right?

Thumb if I go to add another fingerprint and I used the same thumb in orderto like improve.

I guess the reading improved the image that stored within the phone.

If I do it with this with the 60 will say the fingerprint has already been enrolled.

Please try another finger so he won't allow you tow have the same finger registered more than once.

Maybe it has something to do with the optical technology that's at play here in the 60 and other in display fingerprints, smartphones.

But on the S 10 it doesn't work that way.

So, to my pleasant surprise, I could go in there and registered the same thumb print more than once.

And after doing so, I actually ended up with a more accurate, more satisfying experience with the device.

This is the S 10 that I've been using for the purpose of this demonstration.

Have the s 10 e over here on the right and see have added one single fingerprint on this s 10.

Plus, if I click on there, I can add another one.

Now, in this case, we're gonna do is scan in the same finger but the next time around.

Try to do it from different angles in order to improve the ultrasonic recognition.

So I'ma go ahead and just move my thumb around a bit.

Make sure you get those really flat readings on the bottom part and then also the edge readings on the top part.

And now we have two fingerprints of the same fingerprint off.

I wanted to get real crazy.

I could add this fingerprint.

Ah, third time, This is the third breeding for the same finger.

In my experience, it just improves the accuracy and it improves the unlocked functionality of the device.

Some of you have mentioned in the comments.

I've even seen videos made about it that you don't need to hold your thumb on the fingerprint scanner.

This is also true.

You can kind of lift it off, and it sort of makes it seem faster than maybe, you know, you might have originally thought, whether you lift it off or not, it's not really important The point is, you want it to work.

Look, see, see, it's still it's still not 100%.

It still can miss from time to time and say no match.

And there is, ah, pressure component to it, based on how hard you press down.

But nonetheless, it's still, in my opinion, not as good as the capacity of fingerprint scanners that have been on the back of these devices in the past.

But it really improves.

Thean display fingerprint scanner to register the same finger more than once.

I recommend you do it, and I recommend you get all the edges of the finger to improve the recognition.

There is the added security with the ultrasonic technology, so he's gonna be tougher to crack than the same or seemingly similar scanner that exists on a device like this.

The one plus 60.

That's just an image of your fingerprint.

And for whatever reason, it won't let you register the same finger more than once.

Little trick, little hack.

I totally forgot about it because the optical based scanners that I had been using wouldn't allow for it, but it does work on the S 10 as 10 plus, so go for it.
