The long-suffering face unlock, which had been a stumbling block for Google back in the Pixel 4, disappeared without a trace from the Pixel series for three years. While unveiling the Pixel 7 family yesterday, the company briefly mentioned the return of Face Unlock without giving it much thought. And here’s why: if in the case of the Pixel 4, a complex system of LiDAR cameras was used to read the 3D profile of faces, then in the Pixel 7 and 7 Pro, unlocking occurs in the same way as in the most budget smartphones – through the front camera.

While claiming to use advanced AI algorithms, Google does not allow face-to-face purchases or access to secure apps, which still require you to put your finger on the under-screen scanner. In other words, the company tacitly confirms that the reliability and safety of such protection leaves much to be desired. In a separate comment, a Google representative clarified that Face Unlock on the Pixel 7 and 7 Pro is more of a feature for comfortable work than a smartphone security system – its role is played by a fingerprint scanner.
