A lot of users may not know this, but the Samsung Galaxy S10 5G actually features a ToF sensor at the front where the punch-hole cutout is present, which meant that theoretically, the Korean giant could have introduced 3D face unlock to the flagship. Sadly, it was most likely locked down due to a software limitation but it appears that thanks to the latest Galaxy S10 5G Android 10 update, users will have a more secure way of unlocking their handset. Looks like in addition to paying a little extra for 5G support also means you’re getting a little a security in return.

Tipster Max Weinbach spotted a Korean user stating that the Galaxy S10 5G Android 10 beta update introduced 3D face unlock for the flagship. Previously, the ToF sensor could only be used to create a bokeh effect using the front-facing camera hardware to taking images and videos. Fortunately, thanks to the latest update, a new feature has apparently been unlocked. ToF sensors are widely present in several Chinese smartphones to allow for facial recognition and it was surprising that Samsung locked down the capabilities of the front-facing sensor despite stamping a large price tag to the 5G-ready flagship.
