On the Samsung S10 anyone's fingerprint can unlock the phone. The phone was released in March 2019. Samsung promised to fix the software problem.
The conundrum was noticed by a British woman whose husband managed to unlock her phone with his fingerprint when it was stored in a low quality case.
At the time when the S10 was launched, in March, Samsung verified the fingerprint system as "revolutionary". Though, it is more like revolutionarily bad!
The British couple who discovered the security issue said it was a "real concern". Since buying a £2.70 gel screen protector on eBay, Lisa Neilson registered her right fingerprint and then found her left fingerprint, which was not registered, could also unlock the phone. It was found out on the 18 of October 2019. For some reason, the scanner on the phone sends ultrasounds to detect 3D ridges of the user thumbprint to recognise the users finger. Samsung said they were aware of the case of S10's malfunctioning fingerprint recognition and will soon fix the problem and issue a software patch". KaKao Bank told S10 customers to switch off the fingerprint-recognition option to log in to its services until the issue was fixed.
