New phone cases for the Google Pixel 6 and Pixel 6 Pro smartphones have appeared in a number of live shots that were originally shared on a Chinese social media site. The Pixel 6 and Pixel 6 Pro cases were also placed next to a case for the Google Pixel 4 XL to give an idea of their size and design evolution.

Obviously the non XL version is as big as the 4 XL .. and difference between 6 and 6 Pro size is almost negligible. Shame.
