The stated benefits of under-display fingerprint scanners were fantastic. A built-in sensor opens the phone when you simply place your finger on the touch screen as you normally would. While in actuality they are worse than the alternatives, that was the fantasy.

A Synopsis of Fingerprint Scanner History
In the 2010s, cell phones got their first fingerprint scanners. In 2013, Apple released the iPhone 5S with a fingerprint scanner, and a year later, Samsung released the Galaxy Note 4 with a similar feature.
Capacitive technology was used in the earliest fingerprint readers. The sensor is covered with tiny electrodes, and your fingerprint is read by measuring the distance between the electrodes. It varies according to how far apart the ridges on your finger are.

By the end of the decade, fingerprint scanners were a standard feature on most smartphones. But a shift was on the way. With the introduction of Face ID in 2017, Apple began to advance facial recognition. In the meantime, the first in-display fingerprint scanners were being implemented by Android vendor Vivo.
There are still a lot of Android devices with the traditional style of fingerprint scanners, but in-display scanners have become common on “flagship” Android phones. Today, Apple has all but abandoned fingerprint scanners for Face ID—only the “retro” iPhone SE has Touch ID.
Fingerprint Scanners with In-Display Technology’s Potential
The Vivo X20 Plus, which debuted at the beginning of 2018, was the first smartphone with an in-display fingerprint scanner, also known as an under-display fingerprint scanner. It made use of an optical scanner, which uses a tiny camera to take a photo of your finger after shining light on it.
I can still clearly recall how intriguing I found this novel idea. At that time, fingerprint scanners were still frequently found on the front of phones, on the bottom bezel. It may still be on the front without taking up room on the bezel thanks to an in-display fingerprint scanner.
It had the impression of being incredibly cutting-edge. Isn’t it wonderful that you can simply place your finger on the phone’s screen to unlock it after it has automatically detected it? There’s no need to hunt for a particular area on the phone’s back or bezel. Touch the screen to interact!

The early in-display scanners didn’t operate at all in that manner, of course. A fingerprint icon is typically displayed on the screen to serve as a reminder of where you needed to place your finger. Additionally, they ran a lot slower than the fingerprint scanners of the “classic” model.
Yet that was all right. Though there are always issues with cutting-edge technology, the potential is intriguing. I can picture a time in the future when you won’t need to place your finger in a very exact location and wait a brief period of time for it to be scanned. a time when scanning your finger will only require a quick swipe of the lock screen.
The Future We Received Rather
Let’s jump forward to the present day in the year 2022. Still being introduced are high-end Android phones with in-display fingerprint scanners. Samsung has been utilizing the technology since 2018. In-display scanners were not implemented by Google until the Pixel 6 in 2021.
Over the past five years, technology has advanced. Ultrasonic in-display scanners have gradually taken the place of optical in-display scanners, which don’t have the finest security. To map your fingerprint, they employ ultrasonic pulses.
The issue is that these advancements haven’t been substantial enough. The use of an in-display scanner in 2022 is not a huge improvement over 2018 as I had anticipated. In reality, I contend that they still fall well short of the “classic” style fingerprint scanners in terms of quality.
In-display fingerprint scanners, for instance, are a feature of Samsung’s newest and best flagship smartphone series, the Galaxy S22. You’d think it would be satisfactory by now, wouldn’t you? It’s true that various people would have different experiences, but for me, it’s practically useless.
I frequently have to scan my finger three times or more to get it to register. If it weren’t for Android’s “Smart Unlock” function, this would be even more annoying; nonetheless, it’s gotten to the point where I’ve enabled Samsung’s facial recognition technology, which is still inferior to Apple’s Face ID.
Embrace the Face
Having experienced Face ID, I believe I concur with Apple’s assertion that facial recognition is the future. Under-display scanners appeared to have a lot of potential, but their practical application has been far from satisfactory.
The first in-display scanner to debut on a smartphone was almost five years ago. Why do outdated scanners on low-cost Android phones continue to function better than them? Manufacturers of Android devices should concentrate on competing with Face ID if they don’t want to use traditional scanners.
In my experience, a traditional fingerprint scanner and Face ID are both equally quick and accurate. Even though it is far from perfect—for instance, it is less accurate when a mask is worn—it is still quite good. The fact that Face ID is genuinely secure is its main advantage.

For activities like making purchases in the App Store, Face ID on iPhones can be utilized as a security feature. On Android phones, however, this is not true of facial recognition features. If you decide to employ that way on the lock screen, you’ll need a backup security measure for purchases and other transactions.
It would be fantastic to have a phone with a full touch screen that can scan your finger, but that hasn’t happened yet. I’m not sure if we’ll ever get there at this point. It’s time to go to a better project.
