THE Samsung promised for the beginning of next week a update to correct the flaw that makes the sensorultrasonic of the lines Galaxy S10and Note 10unlock with any fingerprint, when the phone has certain types of protective films. In the meantime, the manufacturer instructs users to remove incompatible films and re-register their fingerprints.
According to Samsung, the bug occurs when the ultrasonic sensor finds three-dimensional patterns in the protective silicone films and considers the users’ real impressions. This can affect the Galaxy S10, Galaxy S10 +, Galaxy S10 5G, Galaxy Note 10 and Galaxy Note 10+. (The Galaxy S10e has a reader on the side, not the screen.)
The brand orientation is for users to remove incompatible films until the update is released. Then, it is necessary to do the biometric re-registration, removing all previous fingerprints. The exception is for cases where the film has already been pre-applied; Samsung sells the Galaxy S10 that way in Canada, for example.
After updating the Galaxy S10 and Note 10, it is likely that it will be necessary to re-register fingerprints.
Galaxy S10 unlocks with any fingerprint
The case was revealed this week, involving Samsung’s cell phone line with ultrasonic fingerprint sensor. A silicone film applied to the screen confused the reader and caused the Galaxy S10 to unlock with anyone’s finger.
The incompatibility of the ultrasonic reader with some types of film has already been admitted by Samsung. Because of the extra layer of material, be it glass or silicone, the ultrasonic waves sent to map the fingerprint had difficulty making the biometric reading. Because of this, the manufacturer has always recommended the use of official films.
But it’s not just the biometric sensor that has had problems. Facial recognition can be tricked by photos or videos, including by relatives of the cell phone owner. This was due to the absence of accurate sensors in face recognition.
Up to the Galaxy S9 line, there was an iris reader for biometric unlocking. To reduce the edges of the devices, Samsung eliminated frontal sensors and left only one hole for the cameras.
