Screen size, Viewport, CSS Pixel Ratio
Galaxy S21 Plus has a 6.7-inch screen with a screen size (resolution): 1080px × 2400px, 384px × 854px viewport1, and a CSS Pixel Ratio of 2.8125.
Viewport or Viewport size is the number of software pixels (CSS pixels) present on a screen. Usually, viewport size displays as viewport width in pixels to viewport height in pixels.
Device Pixel Ratio (DPR) or CSS Pixel Ratio is the ratio between the physical pixels (screen size or resolution) and CSS pixels (viewport). Depending on device specification, one CSS pixel can equal one or mode physical pixels. Modern devices have screens with high pixel density resulting in the difference between screen size (resolution) and viewport.
Viewport size = Screen Size (Resolution) / Device Pixel Ratio.
CSS Pixel Ratio = Screen Size (Resolution) / Viewport size.
Key points for development and testing on Galaxy S21 Plus
Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag:
<meta name="viewport" content="width=device-width">.
You can inspect this tag in the head section of an HTML document on Galaxy S21 Plus right in the Blisk app. If this viewport tag is missing, the web application will not be responsive and will overflow the screen, hiding the content from users and leading to a bad user experience.
The form factor of the device represents its primary orientation as a portrait. Landscape orientation is popular on Galaxy S21 Plus as well and should be seriously considered when you develop or test web applications on any mobile.
You also need to consider that the users will manipulate your web application on Galaxy S21 Plus with a finger and stylus because this device has a touch screen that supports touch events. It is important to remember, that users may interact with multiple fingers (multi-touch) and gestures: single tap, multi-tap, swipe, pinch, stretch, zoom, etc. The users are highly likely to use gestures on small touch screens because of seamless interaction and great user experience.
