let me be faster in this intro let me do that again so as you know I've been using the galaxy s 10 as my main device for a period of time now now 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 on lots of device I'm just not using face unlock 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 act video I explained that I wasn't so happy I wasn't enjoying the end 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 more than once I was thinking to myself wait I just came from the oneplus 60 and that didn't work and typically with the 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 of the oneplus 60 you can see two finger prints are registered left thumb right thumb if I go to add another fingerprint and I use the same thumb in order to like improve I guess the reading improved the image that's stored within the phone if I do it with this with the 60 it will say the fingerprint has already been enrolled please try another finger so it won't allow you to 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 fingerprint smartphones but on the s 10 it doesn't work that way so to my pleasant surprise I could go in there and register the same thumbprint 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 I have the s 10 II over here on the right and see I've added one single fingerprint on this S 10 plus if I click on there I can add another one now in this case what I'm going to do is scan in the same finger but the next time around try to do it from diff angles in order to improve the ultrasonic recognition so I'm gonna 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 now if I wanted to get real crazy I could add this fingerprint a third time this is the third reading for the same finger in my experience it just improves the accuracy and it improves the unlock functionality of the device some of you have mentioned it 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 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 a hundred percent it still can miss from time to time and say no match and there is a pressure component to it based on how hard you press down but nonetheless it's still in my opinion not as good as the capacitive fingerprint scanners that have been on the back of these devices in the past but it really improves the in 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 these are gonna be tougher to crack than the same or seemingly similar scanner that exists on a device like this the oneplus 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 base scanners that I had been using wouldn't allow for it but it does work on the s 10 s 10 plus so go for it if you own one of these
