Galaxy viewport — 360 × 780 CSS px
Galaxy is a generic Android preset, not a specific Samsung model. It has the narrowest default viewport in the catalog and is useful for finding overflow.

What this viewport size means
360 × 780 represents the preset browser viewport in CSS pixels, not necessarily the physical display resolution. DPR 3 is reference metadata: the tester does not change pixel density or emulate the device OS or browser engine.
Portrait and landscape
On rotation, check that an overly dense desktop navigation does not appear prematurely. Even when every item fits horizontally, an expanded menu may need vertical scrolling.
What to check
Start with tables, breadcrumbs and long addresses, which can stretch a container. Inspect wrapping filters and visible form labels. A table can have its own scroll area while the rest of the page stays within the viewport.
How to test this size
Open the tester, enter a URL and select “Test website”. In the workspace, choose “Add device” and select Galaxy if it is not already active. Its default size is 360 × 780 CSS px. Rotate swaps the dimensions. The link below opens the tester without automatically selecting a preset.
