Samsung: Anyone's thumbprint can unlock Galaxy S10 bbc.com

The company promises a software fix after a British couple discovers any fingerprint can unlock the flagship device.
A flaw that means any fingerprint can unlock a Galaxy S10 phone has been acknowledged by Samsung.

It promised a software patch that would fix the problem.

The issue was spotted by a British woman whose husband was able to unlock her phone with his thumbprint just by adding a cheap screen protector.

When the S10 was launched, in March, Samsung described the fingerprint authentication system as "revolutionary".
