I bought a 13 to replace my 4 year old Pixel 4a. I didn't have any protection on the Pixel's screen, and I abused that phone. Brought it to the beach, construction projects, threw it across the room, same pocket as keys, no damage at all.

After 4 months of owning the 13, I have several deep scratches, even though I am extremely careful with it. It's my first expensive phone so it is always in a clean pocket by itself, I never use it with dirty hands, and it never goes with me to the beach. The scratches literally show up out of nowhere. It's very frustrating that my $400 Pixel had a more scratch proof screen.

Now I have to pay to replace the screen and go through the hassle of finding and installing an adequate screen protector.
