Face unlock :-
Pixel 4 with Soli radar chip proactively turns on the face unlock sensors when you want to unlock the phone. “If the face unlock sensors and algorithms recognize you, the phone will open as you pick it up, all in one motion,” said Google. Face unlock on Pixel 4 will work in almost any orientation—even if you’re holding it upside down—and you can use it for secure payments and app authentication too.
Soli-powered Gestures :-
Miniature version of Soli, a motion-sensing radar located at the top of Pixel 4 senses small motions around the phone, combining unique software algorithms with the advanced hardware sensor, so it can recognize gestures and detect when you’re nearby. This will allow you to skip songs, snooze alarms, and silence phone calls, just by waving your hand. Motion Sense will be available in select Pixel countries, said Google.
Security and privacy :-
Face unlock uses facial recognition technology that is processed on the device, so that image data never leaves your phone. The images used for face unlock are never saved or shared with other Google services. Face data is securely stored in Pixel’s Titan M security chip. Similarly, Soli sensor data is also processed on the phone, and it’s never saved or shared with other Google services.
