Galaxy S10 has unlocking bug with any digital – Mobile

This week, a report in the newspaper The Sun revealed that the SamsungGalaxyS10 can be unlocked with any printdigital after a cheap film is applied to the screen. Samsung has already said it is aware of the case and is preparing an update to correct the biometric sensor failure.

Samsung Galaxy S10 + biometrics

The Galaxy S10 was the first cell phone to bring an ultrasonic sensor below the screen. This type of reading sends high frequency waves to make the 3D fingerprint mapping. The whole process is done quickly, working even with a wet finger and with the scratched screen.

The problem starts when there is a larger layer for ultrasonic waves to pass through, as is the case with films. In this week’s case, the The Verge reported that, apparently, the problem would have occurred because the biometric registration was done with the film already applied. It is also worth considering that the material was of some type of gel, which may have further confused the reader during registration.

Samsung has even admitted that certain types of film may not work with the Galaxy S10 in Canada and Germany, where all cell phone units already come with a compatible film installed.

Marques Brownlee, from the MKBHD channel on YouTube, did the test with glass films and confirmed that the sensor has difficulty identifying the fingerprint due to the extra layer of material. Skip the video to 7:10 to check out the test:

Galaxy S10 also has flawed facial recognition

What would remain, until the security patch corrects the bug in the biometric reader, would be to use facial recognition to unlock the device … if he also had no problems.

In the Galaxy S9 it was still possible to rely on biometric iris recognition, but in the later model, Samsung chose to reduce the edges, eliminating the sensors and opening only one hole for the front cameras.

This means that without sensors, there is no precise user authentication, as is done with the iPhones Face ID. Some owners, by the way, said they could trick facial verification from photos and videos, even with relatives.

For now, what remains is to enable the numeric password and wait for an update to correct the problem.
