Samsung has implemented one of the most accurate and performant fingerprint readers on its Galaxy S10 and S10 Plus. The in-display fingerprint sensor on Samsung Galaxy S10 and S10 Plus is better than any other of its kind and way more performant and accurate than any standard fingerprint reader. Setting up a fingerprint as a password for your smartphone is an improved method to secure your device. In this post, I will show you how to set up secure fingerprint recognition on Galaxy S10.
Why is Samsung Galaxy S10’s in-display fingerprint sensor useful?
First of all, the technology behind the S10’s ultrasonic fingerprint reader is not entirely new. Many other smartphone manufacturers have already tried on different devices. Huawei, Xiaomi, and Vivo are only a few of those producers that implemented an in-display fingerprint sensor on some of their devices.
However, Samsung managed to improve that instrument and come up with the first 100 percent accurate and fast one. The South Korean tech giant’s ultrasonic fingerprint scanner is, therefore, the most precise and fastest one you’ll find on a mobile device, at this moment.
Besides, setting up secure fingerprint recognition on Galaxy S10 is not only a fast method to unlock your phone, but it’s also a security feature that would keep your private data safe from the peeking eyes.
And the best part of Samsung Galaxy S10’s in-display fingerprint sensor is that it can be used even when the display is off. Also, it allows us to secure access to our apps with fingerprint recognition.
How does the Galaxy S10 and S10 Plus ultrasonic fingerprint reader work?
A standard fingerprint scanner uses either optical or capacitive elements. The capacitive fingerprint scanner concept is widely used in the smartphone industry, and instead of reproducing the image of a fingerprint, as in the optical scanners, it uses electrical charges to track the details of a fingerprint.
On the other hand, the ultrasonic fingerprint reader on Galaxy S10 and S10 Plus is using sound waves reflecting from your finger’s skin to depict its unique fingerprint.
The in-display fingerprint sensor is, therefore, more effective in conduction fingerprint recognition in either high- or low-light conditions, as well as through water, grease, and so on.
