It was recently discovered that the Samsung Galaxy S10 and S10+ have a major security flaw that makes it easy to bypass their fingerprint locks. On a scale of “one” to “not good,” we are definitely towards the right on this one.
To be fair, fingerprint sensors and other biometric security features aren’t ironclad; hackers can successfully get around these kinds of security measures, albeit with a fair amount of work. However, the Galaxy S10’s fingerprint sensor can be fooled with the simple addition of a screen protector or phone case made of silicone, tempered glass, or plastic. The interference from the protective material is apparently enough to confuse the sensor so anyone’s finger tap can unlock the phone. (Ugh.)
