Under Screen Fingerprint Scanner vs Physical Fingerprint Scanners: Winner?

The Vivo X21 UD is finally here (₹35,990), and with that comes the nether display fingerprint scanner. The new technology is the solution to finally having bezel-less displays while nevertheless having a fingerprint sensor in the front. The new sensor takes no visible space, being embedded underneath the display, which makes it look seamless and futuristic. But apart from the looks, is the new under display fingerprint scanner actually that good? Well, I have the Vivo X21 UD with me, and I decided to play to the curiosity in my heed and compare it with smartphones featuring a standard fingerprint scanner. So, would you lot like to see my results? Well then, read on, as we prove you how the under display fingerprint scanner performs against a normal fingerprint scanner:

Nether Screen Fingerprint Scanner vs Physical Fingerprint Scanners

Annotation : For our tests, nosotros will be pitting the Vivo X21 UD with an nether display fingerprint scanner against the OnePlus 6 and the iPhone viii Plus.

Registration Time

We kickoff off with the actual registration of one's fingerprint on the device.

First upward, we have the OnePlus 6. The OnePlus 6 makes apply of one of the fastest capacitive scanners out there, and it shows. It took me merely 8 seconds to register my fingerprint on the OnePlus device, complete with the Edge Input likewise. Additionally, I'd similar to add that it features 1 of the smoothest surfaces, which makes interacting with the sensor all the more seamless.

Adjacent up, was the iPhone 8 Plus, which makes use of Apple'south TouchID. Registering on the iPhone device took me roughly 13 seconds, which is still decent. Yes, information technology does use the aforementioned capacitive touch technology for storing the fingerprint, only the included animations, as well every bit an extra layer of security hashing algorithms (as stated by Apple), do end up making the registration process slightly longer. The surface of the fingerprint scanner on the iPhone 8 Plus is every bit smooth as yous can wait it to be, and positioning it underneath the Habitation button gives it an intuitive impact every bit well.

Lastly, we have the Vivo X21 UD with us. The registration process on this is, well, quite boring, to be honest. While I'll become to the numbers in a 2d, the fact that yous literally have to press (read force) your finger on the screen quite hard to brand the sensor recognize it is quite awkward. As for the time, information technology took me an amazing 22 seconds to register part of the fingerprint only. The complete registration, including the edge input, took me virtually 35 seconds in all, which is just cool.

Information technology is worth noting that both the OnePlus six and the iPhone 8 Plus are using capacitive technology for their fingerprint scanners, which has gone multiple revisions to come to the speed of recognition that it has today. On the other manus, the Under Display finger scanner on the Vivo X21 UD makes use of primitive engineering science, that is expected to be refined over the years. Possibly ane mean solar day I won't accept to press so hard on my screen to register my fingerprint on information technology, but for at present, the Vivo X21 UD takes an clumsily long time to do it. In the end, the OnePlus 6 takes the pb, with the iPhone 8 Plus coming in close, and the Vivo X21 UD lagging in far behind.

Winner – OnePlus 6

Speed

Let's talk about speed, shall we?

The OnePlus six carries the tagline "The Speed You Demand", and the fingerprint scanner on information technology manages to alive up to it. The company claims that the scanner tin unlock the device in just 0.2 seconds, and while I tin can't really give you lot an verbal measure for the same, information technology certainly seems to be equally fast every bit that. The OnePlus 6 unlocks in absolutely no fourth dimension, and there'due south no debating over that fact.

Next up, nosotros took the iPhone eight Plus for a spin. I'm certain a lot of you already know the respond to this, and aye, the iPhone viii Plus does lag behind the OnePlus half dozen in the overall speed. That existence said, I would like to point out the fact that as far as the speed of the fingerprint scanner (or TouchID) is concerned, it is about equally fast every bit the OnePlus 6, coming in at nearly 0.4 seconds. What makes the iPhone viii Plus look slower are the animations, which takes the total time for unlocking almost upwardly to 0.7 seconds.

Lastly, we accept the Vivo X21 UD. The X21 UD takes close to a 2nd to unlock the device, including the cumbersome animations as well. When you await at information technology figuratively, it does indeed seem to be a long time span. Just then again, for the cease user, I don't expect it to matter that much. You lot yet go to apply your device quite swiftly, and while I'm non sure whether the blame for this goes to the Snapdragon 660 SoC (which is conspicuously slower than the Snapdragon 845 on the OP6), it is nevertheless fast enough, peculiarly considering this is a new engineering that the device is using.

One time once again, the OnePlus vi has the atomic number 82, unlocking the smartphone in a blazing fast time of just 0.2 seconds or so. In the context of the comparison of technologies, the fingerprint scanner on the iPhone eight Plus isn't that far backside than the OnePlus half-dozen, merely the animations make information technology rather slower for the finish-user. As for the Vivo X21 UD, it is a relatively newer applied science, and results are bound to be like this. Nonetheless, the speed is quite respectable, and shouldn't really brand much of a difference to the end user.

Winner – OnePlus half dozen

Accuracy

Speed is one affair, but what about consistency?

The OnePlus half dozen has already proven to exist the fastest in this examination, but is the fingerprint scanner on the device just equally accurate? Well, I tried using the device a lot, and in my testing, the OnePlus 6 was able to correctly recognize my fingerprint viii out of 10 times. Truth be told, I reckon that this is due to the bad-mannered shape of the scanner, since the scanner on the OnePlus 5T, which uses the same technology, has a higher accurateness than this.

Next, we have the iPhone eight Plus, and male child is this thing gold. In my experience, the Apple device managed to unlock the device accurately with a success score of nine out of 10, which is only peachy. Yes, information technology's non perfect, but information technology gets simply equally close to perfection.

Lastly, I tested out the Vivo X21 UD. Truth be told, the under display fingerprint sensor on this device is sort of inconsistent, which was something I expected from the start. The Vivo X21 UD managed to recognize my fingerprint just 6 out of x times. Considering this is still a newer technology, this was something one would accept predictable. Too, information technology is worth noting that the major issue with this inconsistency is the fact that you have to actually press quite hard on the screen, as opposed to the simple touching of your finger on the OnePlus half dozen and the iPhone 8 Plus.

Bottomline, the iPhone viii Plus takes the lead here, with the OnePlus 6 coming in only behind it. Once over again, the Vivo X21 UD is backside the competition, just then again, it's not a complete disappointment equally some of y'all might take expected.

Winner – iPhone eight Plus

Screen Protector

Protective filming, anyone?

Equally far every bit working under screen protectors is concerned, the OnePlus 6 and iPhone eight Plus both characteristic capacitive fingerprint scanners, so they won't piece of work with any sort of protection on superlative of them. In fact, ane might recall that all the screen protectors have a dedicated cut out for these fingerprint scanners.

On the other hand, the Vivo X21 UD makes use of advanced optical fingerprint scanning technology, which can piece of work under whatever visible surface. In my testing, the scanner on the X21 UD worked just as fine under screen protectors of all kinds, which is a great thing to have.

Winner – Vivo X21 UD

Not-Ideal Atmospheric condition

Well, those were all the standard testing parameters. But things can get crude at times, right? Let's come across how the iii devices fare in this aspect:

Nosotros beginning off with the OnePlus 6 under oily conditions. I tried opening the device with my extremely oily hands (you know how Indian nutrient is), and interestingly, the OnePlus vi faced no issues at all. It opened at the same pace as it usually does. I took things further with using the fingerprint sensor with moisture on the summit as well as some dirt on top, and it had the same story. The OnePlus vi exhibited the same speed and accurateness as it did in normal conditions, which is just great.

Side by side upwards, I decided to examination the TouchID on the iPhone 8 Plus under these weird atmospheric condition. Only every bit I expected, the iPhone eight Plus featured pretty well, just existence a tad bit slower than its usual speed. I was able to unlock the device with oily fingers and fingers with a lot of dust on top of them. The speed was slightly slower but still negligible. That being said, the Apple device just failed to recognize my finger with even the slightest wet on top of it.

In the end, nosotros have the Vivo X21 UD, and information technology surprisingly was able to work quite well. Now, it yet had the same level of inconsistency with its recognition, just it was able to work just equally well the iPhone 8 Plus. What that means is that while I was able to unlock the Vivo X21 UD with my oily as well as dusty fingers, information technology failed to work nether moist atmospheric condition. I volition, however, bespeak out that in one case out of 10 tries, the Vivo smartphone was able to recognize my fingerprint, but I reckon that was just luck.

Bottomline, the OnePlus 6 is the clear winner here, outsmarting both the iPhone 8 Plus and the Vivo X21 UD. Apart from the inconsistency that we discussed previously, both the Vivo X21 UD and the iPhone 8 Plus perform similarly.

Winner – OnePlus 6

Under Display Fingerprint Scanner: Steady Steps into the Futurity

Well, I did a thorough testing of the under brandish fingerprint technology showcased by the Vivo X21 UD, and pitting it against 2 of the best fingerprint technologies bachelor on both Android and iOS devices. While Apple has clearly ditched the TouchID in favor of the infamous FaceID on the iPhone X, its fingerprint technology still remains valid in today's globe. The OnePlus 6, on the other paw, is the articulate winner and might stay so in the coming years also. That existence said, the under display fingerprint sensor on the Vivo X21 UD, despite being in its early stages, manages to requite the current standard a decent competition.

Discarding the actual numbers, the end-user might not even notice all the differences that I've highlighted above, and thank you to the efficient utilise of space, might end upwardly liking the nether display fingerprint sensors. For what it's worth, the Vivo X21 UD showcases the advancements we've made in the biometrics department, and what the futurity holds true for the upcoming smartphones.
