Samsung Galaxy A30: CSS viewport of 412 × 892 px, resolution and responsive test

Why test your site on Samsung Galaxy A30?

CSS viewport resolution of Samsung Galaxy A30

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.

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 A30

The device pixel ratio of Samsung Galaxy A30 is 2.625. In other words, a 1-pixel square in CSS occupies 2.625 pixels on the panel. An image exported at actual size will appear blurry.

• 1080 pixels in width
• 2340 pixels in height
• 403 pixels per inch (ppi)
• 6.4 inches diagonal, or 16.3 cm

Mobile FIRST does not yet include Samsung Galaxy A30, 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 A30 — Select Samsung Galaxy A30 from the list of devices. The viewport switches to 412 x 892 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.
