Why test your site on Samsung S6?

Narrow viewport

With only 360 pixels wide, Samsung S6 is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

4x density

Each CSS pixel of Samsung S6 is rendered by 4 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

Older hardware

The hardware of Samsung S6 dates from 2015. Its processor makes costly animations, heavy scripts, and display times visible that recent devices mask.

CSS viewport resolution of Samsung S6

This is the width your CSS considers. All your breakpoints and media queries compare to this value, not the number of physical pixels on the panel.

  • 360 pixels in width
  • 640 pixels in height

The height remains indicative: Safari, Chrome, and other mobile browsers reduce the visible area with their address bar, which folds on scroll.

Be cautious when analyzing your statistics: some tools only report the manufacturer resolution, never the CSS viewport presented here.

Pixel density of Samsung S6

4

The device pixel ratio of Samsung S6 is 4.

Your images should therefore be exported 4 times larger than their display size, otherwise they will appear softened on this screen.

Manufacturer resolution of Samsung S6

This is the actual number of pixels on the panel. This value does not affect your layouts, but it's the one reported by technical specifications and most analytics tools.

  • 1440 pixels in width
  • 2560 pixels in height
  • 16:9 Screen ratio

577 pixels per inch (ppi) · 5.1 inches diagonal, or 13 cm

Media queries and code snippets for Samsung S6

These snippets are generated from the exact characteristics of Samsung S6. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Samsung S6 and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 639px) {
  /* Samsung S6 */
}

Density media query

Serves high-resolution images to screens of at least 4x.

@media only screen and (-webkit-min-device-pixel-ratio: 4),
       only screen and (min-resolution: 384dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of Samsung S6.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'samsung-s6': '360px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 360px)').matches;
const isHighDensity = window.devicePixelRatio >= 4;

Meta viewport tag

Essential for Samsung S6 to use its CSS viewport and not a simulated width of 980 pixels.

<meta name="viewport" content="width=device-width, initial-scale=1">

Free Samsung S6 simulator

Mobile FIRST does not yet include Samsung S6, but a model with the same format is available. You can already validate your breakpoints and display density.

This is where the difference with Chrome DevTools' responsive mode is seen: DevTools resizes a window, the extension replicates the device's browser and allows exporting shareable screenshots and videos.

  1. 01 Install the extension Add Mobile FIRST to Chrome, Firefox, or Edge. Installation is free and requires no account.
  2. 02 Open the page to test Go to the URL to check, including a local address like localhost:3000.
  3. 03 Choose Samsung S6 Select Samsung S6 from the list of devices. The viewport switches to 360 x 640 pixels, and the mobile User-Agent is applied.
  4. 04 Check rendering Scroll, change orientation, test your forms, then capture an image or video to share.

Models sharing the format of Samsung S6

These 4 devices share exactly the viewport of 360 x 640 pixels and the 4x density of Samsung S6. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
