Whether it’s Apple’s Face ID or Huawei’s face lock, the 3D-mapping of your face makes it less easy to spoof, and the presence of fingerprint scanners has become full. However, LG has gone a step further with its recently unveiled LG G8 ThinQ when it comes to biometrics, hardware, and optics. Apparently, this is how the company intends to make sure its latest flagship makes a mark, something which its predecessor failed to do, despite having decent all-round specifications.

The LG G8 ThinQ features an updated front shooter which the company calls Z-camera. It basically employs a ToF sensor which can sense gestures, motion, and depth. However, here is where things go awry; the front camera system has a feature called Hand ID, with which you can unlock the phone by holding your palm in front of the selfie camera. It uses the pattern of veins in your hand to identify you and while in theory, this sounds fine, various reports are suggesting that the system takes an effort to work correctly.
