The Ultra layout target is unchanged
The current dataset places both Ultra generations in the same viewport and density group.
Galaxy S26 Ultra screen size
Galaxy S26 Ultra: 6.9″, 1440 × 3120, 498 PPI, 384 × 832 CSS viewport at DPR 3.75. Its tracked display and viewport references match the previous Ultra generation, making it a named-device update rather than a new responsive breakpoint.

Responsive testing plan
Galaxy S26 Ultra responsive workflow
Use the 384 × 832 CSS px at DPR 3.75 as a real QA target, then pair it with nearby widths for regression testing.
Model-specific checks
- Reuse existing Ultra viewport automation, but update the named-device matrix and screenshots.
- Run the same critical flows on the base Galaxy width to catch compression that the Ultra may hide.
Values marked official come from manufacturer specifications; calculated values are derived from them; reference values are developer layout references and can vary with browser, zoom and operating-system settings.

Model-specific guidance
What this means for layout and testing
Reuse the regression target carefully
Teams can reuse the primary layout target while still updating the named hardware in device and screenshot coverage.
Do not replace the base Galaxy test
The wider Ultra reference cannot expose every issue that appears on the narrower base-model viewport.
