A three-generation continuity point
The adjacent base models retain this layout width and density, which lets teams distinguish browser or operating-system changes from true responsive changes.
Galaxy S25 screen size
Galaxy S25: 6.2″, 1080 × 2340, 416 PPI, 360 × 780 CSS viewport at DPR 3. Sitting between two base Galaxy generations with the same CSS canvas, this model is a continuity check for compact Android layouts rather than a separate breakpoint target.

Model-specific guidance
What this means
Compact spacing remains the main value
Its narrower canvas is better suited than the Ultra to expose crowded toolbars, rigid dialogs and form controls with long labels.
