Samsung has sent a notification to the Galaxy S10, S10 +, Note 10, and Note 10+ devices that a live fix (OTA) related to the security issues in the smartphone-embedded fingerprint sensor will arrive in the next 24 hours. The notification indicates that the problem concerns the S10/S10+ as well as the notes 10 and Note +.
This is interesting because it seemed at first that the security breach was present in the Samsung Galaxy S10 series. According to Samsung, some screen protectors have a textured pattern that resembles that of a fingerprint. When registering a fingerprint with a screen protector applied to the smartphone, the device saves the screen protector pattern instead of your finger. Any user can then unlock it.
The fact that the ultrasonic display becomes more accurate as it is used makes things worse. It is unclear whether Samsung plans to make any changes to its third-party certification program for screen protectors. All of Samsung’s flagship products of 2021 come with preinstalled display protectors.
Samsung claims that all third-party screen protectors must be removed from the smartphone. Also, once the update is available on your S10, S10+, Note 10, or Note 10+, you will need to re-register your fingerprint sensor.
