My pixel 8 does not stay where I put it. Without a case, it will slide right off of any slightly tilted surface.

It should be illegal to put glass on the back of a phone.

I agree so much. I get why: "Designers" consider plastic to be low-class, metal is radio-opaque, so that leaves glass as the only option even though it has zero functional advantages over plastic (glass is heavier and more fragile).

Imagine if it was a panel of plastic, and that you could easily replace it if it got too scuffed up.
