Samsung may bring a new way to unlock phones with your face on the Galaxy S27 Ultra. The exciting part is that it could be very secure without needing a large cutout or notch. This means the phone can stay sleek and all-screen.

According to the information, the new technology is called Polar ID. Unlike normal face unlock, which uses 3D sensors and many parts, Polar ID works by looking at how light reflects off your skin. Everyone’s skin reflects light in a unique way. 

The new system is also very fast. When you look at your phone, it sends out infrared light and captures both the image and how the light reflects. This happens in about 180 milliseconds, so unlocking your phone is almost instant.

Polar ID is much smaller than current face unlock systems. Normal systems need many parts, like cameras and projectors, which take up space. Polar ID combines everything into one module that is 50% smaller. This means Samsung could fit it inside a small punch-hole camera, keeping the phone’s screen clean and smooth.

Right now, this is just a rumor as Samsung has not confirmed the Galaxy S27 Ultra’s final features. But if Polar ID works as expected, it could make Samsung phones more secure and stylish. Stay tuned for more information.
