Why test your site on Samsung Galaxy J5?

Narrow viewport

With only 360 pixels wide, Samsung Galaxy J5 is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

Older hardware

The hardware of Samsung Galaxy J5 dates from 2015. Its processor makes costly animations, heavy scripts, and display times visible that recent devices mask.

2x density

With a density of 2x, Samsung Galaxy J5 provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.

CSS viewport resolution of Samsung Galaxy J5

This is the resolution that interests designers and developers the most, as it determines breakpoints and the definition of media queries. In practice, it's the only one mentioned in a stylesheet.

  • 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 Galaxy J5

2

The device pixel ratio of Samsung Galaxy J5 is 2.

In other words, a 1-pixel square in CSS occupies 2 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of Samsung Galaxy J5

This resolution is the hardware's. It explains the display's sharpness, but it's never the one to target in a media query.

  • 720 pixels in width
  • 1280 pixels in height
  • 16:9 Screen ratio

294 pixels per inch (ppi) · 5 inches diagonal, or 12.7 cm

Media queries and code snippets for Samsung Galaxy J5

These snippets are generated from the exact characteristics of Samsung Galaxy J5. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Samsung Galaxy J5 and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 639px) {
  /* Samsung Galaxy J5 */
}

Density media query

Serves high-resolution images to screens of at least 2x.

@media only screen and (-webkit-min-device-pixel-ratio: 2),
       only screen and (min-resolution: 192dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of Samsung Galaxy J5.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'samsung-galaxy-j5': '360px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 360px)').matches;
const isHighDensity = window.devicePixelRatio >= 2;

Meta viewport tag

Essential for Samsung Galaxy J5 to use its CSS viewport and not a simulated width of 980 pixels.

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

Mobile FIRST does not yet include Samsung Galaxy J5, 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 Galaxy J5 Select Samsung Galaxy J5 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 Galaxy J5

These 5 devices share exactly the viewport of 360 x 640 pixels and the 2x density of Samsung Galaxy J5. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
