Anything from Spigen. I like the Liquid Air on my S23, and it's available for the S25U as well. I've heard the Thin Fit is also decent, and they have "Optik Armor" cases that cover the camera lenses for even more protection, but I find those really fucking ugly and bulky.

You better get one unless you want the phone's screen to get microscratches within 6 months or so. I just use a basic glass protector that a guy installed for me for like 6 bucks at a phone accessories shop.
