LG's next flagship smartphone could feature 3D face recognition, according to South Korean media.The LG G6 could have 3D facial scanning that would allow G6 owners to unlock their phone with a full-face scan rather than a fingerprint or passcode, industry insiders told The Investor.The reports come after similar claims that Apple will use the tech for its upcoming iPhone.Meanwhile, the Samsung Galaxy S8 also has similar features, in addition to an iris and fingerprint scanner. However, the facial recognition tech appears to not be three-dimensional and can't be used to authenticate a user's Samsung Pay information, according to Ars Technica.
