One of the selling points of the recently released Samsung Galaxy S10 includes the combination of Qualcomm’s first ultrasonic on-screen fingerprint technology. It is believed that the ultrasonic sensor is safer and better for wet hands. Nevertheless, recent tests by netizens show contrasting results for the Samsung Galaxy S10.
Actual measurement found that the ultrasonic fingerprint is indeed perfect for a wet hand but when the hand is too dry, easy to fail. At the same time, the evaluation shows that the Galaxy S10 unlock is not as fast as that of iQOO or Xiaomi Mi 9. In terms of security, the Samsung Galaxy S10 on-screen fingerprint is also vulnerable.
This is the second time that the vulnerability of the Galaxy S10 fingerprint sensor is getting a poor review. Earlier, Reddit and Imgur user, Darkshark, shared a simple crack of the S10 fingerprint sensor by using a 3D printed resin mold. It is not difficult to make such a resin fingerprint method. First, the fingerprint is printed on the glass. The mobile phone takes a clear detail picture, then uses Photoshop to add a mask which then imports it into the 3ds desk, and finally uses a photonic resin printer to finish it.
