The Pixel 6 and Pixel 6 Pro designs have already leaked and now have the latter's rear-facing cameras. Apparently, Google has finally equipped a Pixel smartphone with a periscope camera, which would be a huge change for the Pixel series.

I hope that this year Google will finally use a newer, bigger sensor for his main camera as the one in Pixel 5 does shows it's years.
