Samsung Electronics has released a software update for the Galaxy S10 and Note10 series smartphones. It is designed to solve a serious security breach, thanks to which smartphones could be unlocked with any fingerprint.
The problem was that certain types of protective films interfere with the correct operation of ultrasound fingerprint sensors, which take three-dimensional patterns on films for the user’s fingerprints and allow the device to be unlocked.
As a temporary measure, the Korean manufacturer advised to abandon the use of non-certified protective screen coatings until the update is released, delete the old fingerprint data and re-register fingerprints.
After the Korean manufacturer recognized it and promised to release a software update with a fix, some banking applications began to block smartphones as unsafe. Now the situation should be resolved.
