Samsung‘s flagship smartphone Galaxy S10 5G launched with some high configurations. On the rear, the phone features a quad camera setup. The ultra-wide-angle, telephoto and standard lenses that are present on the S10 and S10 Plus are paired with a fourth Time of Flight (ToF) camera on the S10 5G to accurately capture 3D depth data. This ToF camera is also present on the front next to the standard 10-megapixel selfie camera. It is one of the kinds of smartphones that comes with the ToF camera on both fronts as well as the rear of the phone. But at the time of launch, Samsung could not explain the purpose of the ToF sensor at the front.
But now Samsung knows what Samsung’s ToF sensor is capable of. Samsung has released the One UI 2.0, which adds 3D facial recognition on the phone. The new change has been unveiled by the Twitter user @TEQHNIKACROSS. That will make the face unlock feature much-more secure. Before the update, that phone was using the front-face camera for face unlock. That would let anyone unlock the phone with the owner’s photos also. But that is not the case anymore.

While a normal camera uses light-sensitive diodes on the sensor to absorb light, a TOF sensor both sends out an IR blast and collects the light and depth data based on that blast. The IR beam map your face in 3D using the time it takes for the light to be reflected back (for example, the light from your nose will have a shorter ‘time of flight’ since it’s closer to the camera).
The One UI 2.0 update is currently available to the users of Korea. But it will expand to the other regions soon.
