Seoul, Oct 18: Samsung has reportedly said it will roll out a security update to fix a major vulnerability that let unregistered fingerprints unlock the firm's flagship Galaxy S10 as claimed by a British user, the media reported. The user named Lisa Neilson had installed a third-party, gel-based screen protector on her Galaxy S10, which apparently did not work well with ultra-sonic, in-display fingerprint scanner on the device. Neilson spotted the issue when her husband unlocked her phone with his thumbprint, when it was stored in a cheap case.

When the S10 was launched in March, Samsung described the fingerprint authentication system as "revolutionary", the BBC reported on Thursday. South Korea's online-only KaKao Bank told customers to switch off the fingerprint-recognition option to log in to its services until the issue was fixed, the report added.

The South Korean handset maker has, however, not provided any timeframe for the roll out of this particular security patch. It is also unclear which all phones or models are affected but given that the Galaxy S10, S10+ and the new Note 10 all use ultra-sonic fingerprint sensor, it is quite likely that all these devices suffer from the same issue, according to Mashable.
