How to prevent someone using a photo to defeat facial recognition screen lock?
My wife’s Android phone, a Galaxy S4, has a feature that uses facial recognition to unlock the device. One criticism I’ve heard criticism of this method is that someone can just use a photo of you to unlock it. Is there a way to prevent someone from using a photo to defeat the facial recognition security lock?
I’m not sure about that particular device, but the ones I’ve used have a setting that requires a blink before it will unlock to ensure that a photo isn’t used. Check in your lock screen settings to see if the S4 has this option.
