I love the camera bump on the Pixel 6. I made a leather belt pouch¹ for it for use on trips and hiking, and the camera bump sits neatly on the edge of the front of the pouch (the back part curves around as a flap over the top). It gives my fingers exactly the right grip to grab it and get a solid grip on the whole device as I lift it out of its pouch.

Never used a case for any phone I've owned.
