Starting with the Pixel 3, Google has prepared special-use wallpapers for its phones that can be seen in renders and other promo materials, displaying the generation of the device in large type. But despite only being used for marketing purposes, the backgrounds have been highly sought after by fans. Some artists have gone so far as to create near-pixel-perfect copies in the absence of their official versions. Now, Google has made some of these promo wallpapers available to Pixel 4 and 4a users.
