Samsung adds 3D face unlock on the Galaxy S10 5G with One UI 2.0

Samsung's Galaxy S10 5G is the most expensive, and the most feature-packed, of the bunch. Alongside its 5G chops, the phone is also the only one in the series to have a ToF sensor, both on the front and the back. While ToF sensors can yield wonders for portrait mode with the main camera module, they can also enable real-time 3D facial scanning.

Twitter user @TEQHNIKACROSS  who realized that Samsung had enabled the TOF camera for face unlock after installing the latest One UI beta on his Korean Galaxy S10 5G. While this won’t change the face unlock experience a lot, it does make it more secure. Before this update, the phone would use the front-facing camera only for face unlock. This is by no means secure. While it was fast and accurate, it still left the phone open to unlocking by using a photo of the owner. The Galaxy S10 5G should no longer have this issue.

Here is the tweet where he posted the picture of the 3D Scanner working,

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 red beam you see below is that IR blast being sent out of the Galaxy S10 5G by the ToF camera.

If you have a Galaxy S10 5G and want this update, you’ll need to wait for One UI 2.0. The S10 5G is currently available in Korea for the One UI beta and soon it will be available on the other regions too. If you have an S10 series phone running the One UI 2.0 beta, One UI 2.0 beta 3 is rolling out to devices right now.
