[[It's not 100% clear but it seems that the problem only occurs if you put the screen protector on before recording your fingerprint. If you record the fingerprint and then add the protector it does not allow you to unlock the phone as it sees a vastly different print. In other words, a screen protector is not a "master key" for any S10! Please correct me if I am wrong.]] Edit: On second reading of the article it looks like a screen protector might actually be a master key for any S10 phone. That's a really big design flaw! (Thanks to computerex for making me read the article more critically.)

That doesn't appear to be the case based on the reporting. > After buying a £2.70 gel screen protector on eBay, Lisa Neilson found her left thumbprint, which was not registered, could unlock the phone. This suggests that the issue started happening after putting on the screen protector, and after recording the fingerprint.

From what it seems, it records a "flat" fingerprint, because the screen protector is obviously a flat layer on top of the device. So any haptic touch only activates this flat fingerprint

  Good explanation. Makes sense.
