We know the Google Pixel 4 is coming. What isn’t clear yet is what the new smartphone will have. We already know that there is a secondary camera on this device, which is a first for a Pixel. But we don’t know what kind of camera it could be. A teardown of the Google Camera app shows what we could expect. Version 6.3 of the app shows changes in the code that reference Sabre, which is Google’s codename for its Super Res Zoom. There are also some new sensor IDs for the camera that weren’t seen in version 6.2 and one of these references a rear telephoto lens, making us believe we’re getting a zoom lens. And that this lens could use Google’s Super Res Zoom to increase zoom distance digitally.
Aside from that, a front-facing IR sensor was seen in the code. This suggests that the Pixel 4 is getting facial recognition. Its presence in the Camera app suggests it could be used for Playmojis or even Google’s take on Apple’s Animoji. The Pixel 4 is slated to come out around October 2019.
