At least it still stops butt-dialing

Being able to unlock a phone with a finger instead of a fingerprint is certainly more convenient, but sometimes convenience isn't worth the cost.

Graham Cluley has an interesting theory about how this problem works (that enrolling with the screen protector on means you enroll a fingerprint without ridge details), but doesn't see how a software update can fix it - and in the strictest sense he's right that a software update isn't going to make the ridge details magically appear, but the software update would be able to detect the absence of those ridge details. In essence it could detect when poor biometric data has been used for enrollment and protect users from the consequences of this failure by alerting them to it and/or refusing to use poor quality biometric data.
