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 fingerprint just by adding a cheap screen protector.

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

The British couple who discovered the security issue told the Sun newspaper it was a "real concern".

After buying a £2.70 gel screen protector on eBay, Lisa Neilson found her left thumb print, which was not registered, could unlock the phone.

She then asked her husband to try and both his thumbs also unlocked it.

And when the screen protector was added to another relative's phone, the same thing happened.
