He Live X20 Plus UD became a few months ago the first smartphone to introduce the fingerprint sensor under the screen , below the surface of the display. Soon the first ones arrived tests to check your functioning , but today we bring you a video with a more radical test. A video in which they try to find what is the limit under which this sensor is able to read the fingerprint of the user.
He fingerprint sensor was established as the security system and unlock for excellence in smartphones. Some brands integrate it in the back, but others choose to accommodate it in the front, inserted in the Home button. An alternative that is of the taste of many users for its advantages of use versus its positioning in the back. However, the tendency to design all screen phones , with hardly any frames, has encouraged technology to take its course and offer us an alternative. Apple has opted for facial recognition Face ID. The other alternative is none other than the integration of the fingerprint sensor on the screen itself.
As we indicated at the time, the Live X20 Plus UD is currently the only market model to make use of the technology necessary to integrate the fingerprint sensor under the screen . However, there are reasons to believe that it will not be the only one, but that it aims to be a very popular security solution in the next generation of smartphones.
Therefore, the test operating limits of this kind of biometric sensor It becomes especially interesting. For that purpose, the popular Youtuber Marques K. Brownlee, MKBHD , wanted to show if the sensor of this Vivo X20 Plus UD is able to work under any daily situation that can occur in our day to day, as well as under somewhat more extreme conditions.
In the first phase of the test, Marques contrasts the operation of the ClearID sensor of the Vivo with the Touch ID of the iPhone by wetting his own finger and the surface of the sensors with water. Both models present the same difficulties to carry out their task of digital recognition.
The second phase is to emulate the use of the fingerprint sensor when we are eating, with fingers stained with sauce. In the same way, there is a moment to check if the screen protectors manufactured with different materials affect the performance and effectiveness of the sensor. In a sequence of the video we can even see how, despite putting a cracked glass screen protector, the sensor is still working.
However, there is also room to test in extreme conditions the operation of the fingerprint sensor under the screen. Ultimately, Brownlee not only scratches the surface on which the Vivo X20 Plus UD fingerprint sensor is located, but uses a sandpaper for scratch the screen of the smartphone of Live. Interestingly, except in the test with water, the fingerprint sensor under the display is extremely effective, although this first generation of the sensor has to be optimized to a greater extent to accelerate the process of identification of the fingerprint.
