Samsung has sneaked a 3D form of Face Unlock into the 5G version of the Galaxy S10 with its latest update. It works on this variant only as it has a time-of-flight (TOF) sensor in its front-facing punch-hole. Therefore, this phone's facial recognition may now approach iPhone-like levels of security and accuracy.
