As we know, Google will hold a new product launch conference on October 6, at 23:00 (Beijing time). At this event, the company will launch a variety of new accessories such as the Pixel 7 / Pro series of phones and the Pixel Watch. Among them, the Pixel 7 / Pro series will be equipped with a Tensor G2 processor.
But ahead of the launch, Google releases the Android 13 QPR1 Beta 1 update for Pixel phones. According to a report by 9To5Google, in the code of Android 13 QPR1 Beta 1, Google mentioned the face unlock feature.
The code mentions: “Face unlock works best when there’s plenty of light and you’re not wearing a mask and dark glasses.” Among them, “sufficient light” means that the face unlocks function may only be done based on the camera, not the face recognition based on the infrared camera and Soli sensor used on the Pixel 4.
According to the report, the face unlock-related code found this time is named “Traffic Light”, and the related code was only found on the Google Pixel 6 Pro running Android 13 QPR1 Beta 1, while the Pixel 6 and Pixel 6a were found. There is no relevant code on the above, which means that face unlocks may only be supported on the Pixel 6 Pro, and the feature is expected to be updated after the release of the Pixel 7 / Pro series phones.
It is reported that the front camera of the Google Pixel 6 Pro supports Dual Pixel Autofocus (DPAF), while the Pixel 6 and Pixel 6a do not support this feature, which may be the reason why only the Pixel 6 Pro supports face unlock.
In Pixel 4, Google dropped support for fingerprint unlocking in favor of face unlocking. This feature is powered by the Pixel 4’s built-in Soli sensor. At the same time, the Pixel 4 has two infrared cameras that can see the shape of a person’s face, rather than relying only on the front-facing camera to recognize flat images. On the Pixel 5 and Pixel 6, Google ditched the Soli sensor in favor of a fingerprint sensor.
