[Slow Motion] Physical vs Optical vs Ultrasonic Fingerprint Sensor Speed and Reliability Test

Ever wonder how your Smartphone Fingerprint Sensor works? Or how fast and reliable it is compared to other Fingerprint tech? I test out their speed in slow-mo, and reliability with dry, wet, and oily fingers between a Physical (Sony), Ultrasonic (Samsung), and Optical (OnePlus) Fingerprint Sensor!

So here's my argument in favor of physical fingerprint reader:

The reason why I would always choose a physical fingerprint reader is because I can put my hand in my pocket (because that's where my phone is most of the time), pull my phone by grabbing the phone by the fingerprint sensor, and by the time I've pulled the phone out, it will already be unlocked. Now one can argue how it won't really save a lot of time, but it's not about saving time, it's about doing everything in one motion.

With the in-display fingerprint sensors, you still have to pull the phone out and then scan your finger because of the proximity sensor not allowing the display to turn on in your pocket, and even if a phone's under-display fingerprint sensor works in the pocket, you have to hit it at the right spot which can be a hit or miss, which will again require you to scan your finger after you've pulled your phone out.

And face recognition is just the inferior way of unlocking a phone.

Dam you're the most under rated channel! Your comparison tests and ideas are amazing. Hope to see you at a million subscribers one day. Much better than half of the other garbage channels out there who think they are very big tech gurus when in reality they are just reading out what's written on the box.

I love my S10's Ultra Sonic Fingerprint reader. Very reliable. Ultra Sonic has brought me back into using Fingerprint sensors again!

1:14 You're using the side mounted sensor inappropriately. You don't need to hold your finger on the sensor, just a moment of life touch is enough to wake the phone in no time. You can try tapping your finger as fast as you can, it still responds quickly

Ultrasonic sensors are 3D and optic sensors are 2D which in terms makes them less secure....but....Ultrasonic sensors are a nightmare with ANY screen protector, including Dome glass. Especially if your fingers are completely clean and grease free (e.g. immediately after washing your hands). To the point that the are not usable and I always end up using face recognition...licking your finger helps, but I/m not doing that 50 times a day. There is just NO way I will use any flagship phone without a screen protector just to use the ultrasonic sensor so I really hope Samsung switches to optical soon.

The water test was unfair. For one, you have to put a bit more pressure on the ultra sonic sensor. That's just how it's made, wet or dry. And 2, it's literally telling you to press a bit harder when your finger was wet. If you know Samsung, you know this. So the error is not on Samsung, it's on the user.

For the first test which is the speed test, you should turn on the unlock animation for the samsung or else it will appear slower because the animation makes the optical sesor phone ones appear faster

You are bringing out true test of a phone, for me you are the best reviewer on youtube you deserve millions Followers.

Oh my god you are the best youtuber i watch all of your video and download some too

[madhusudantiwari]

Well physical (capacitive) fingerprint sensor are much more durable, secure and cheaper in comparison to optical or ultrasonic some even work after being scratched. Only downside being that they dont work when fingers are oily or wet.

[icentuche]

The one with water you clearly was not pressing it you kept on tapping it. Even when it said press harder. I caught you on that one. With water Ultra sonic works always. You just need to tap harder

[Divyesh_Sinha]

I knew the one on the sony will definitely loose
But didn't expect Samsung to loose in the water test😂

[OskaIvanovichSmirnov]

You should test ultrasonic vs optical during bright sun light. Optical fs really hates bright lights 😂

[jumpmax]

In mid range phones with physical fingerprint scanner its lightning fast like in realme huawie oppo vivo but if ur fingers are wet it will not unlock also if ur fingers are oily it will not unlock

As someone with a Pixel 5a (a $400 phone that has a rear fingerprint sensor like its 2016 or something) i can say that rounded rear fingerprint sensors are the absolute worse - never once has it taken me only 1 attempt to open the phone in my 3 months of use and most of the time it locks the phone before it can actually detect my fingerprint. Honestly rear rounded fingerprint sensors are just a huge steaming hot pile of garbage, do yourself a favor, and dont buy yourself a phone with a round rear fingerprint sensor if you plan to use a lock screen.

Wasn't expecting the ultra sonic to choke on the water test. Water is a great conductor of sound and humans are made of water, so what happened? Maybe the speed of sound in water is too slow compared to glass?

Change ur channel to TechUnick. This was a really smart video. Love ur work as always. Good job bro ❤️

I'm not interested in the optical sensor because it is the least secure. The other two, ok. I have both the Note 10+ (ultrasound scanner) and the Xperia 1 ii (physical scanner). In my day-to-day experience, both can be unreliable at times. BUT I do prefer the physical sensor on the Xperia because of ergonomics plus the fact that my first touch on a phone is NOT a big thumb print on a freshly cleaned screen. By the way, in normal conditions, no wet or greasy thumbs, the Xperia is super quick and reliable.

Such good content ❤️❤️❤️ subscribing forever....

Dude speed doesn't matter, what matters is there level of security.
So which is more secured?
