With a ratio of 20:9, Samsung Galaxy Note20 displays a lot of height for little width. Sections designed in landscape become endless columns, and full-screen visuals are poorly cropped.
With a density of 2.625x, Samsung Galaxy Note20 provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.
The 412 x 915 pixels viewport of Samsung Galaxy Note20 rarely matches the round breakpoints of frameworks. It is precisely between these values that layouts break.
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.
2.625
The device pixel ratio of Samsung Galaxy Note20 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.
This resolution is the hardware's. It explains the display's sharpness, but it's never the one to target in a media query.

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.
These 4 devices share exactly the viewport of 412 x 915 pixels and the 2.625x density of Samsung Galaxy Note20. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
The neighboring formats of Samsung Galaxy Note20 are the ones to test right after, as they reveal poorly placed breakpoints.

The CSS viewport of Samsung Galaxy Note20 measures 412 pixels wide and 915 pixels high. This is the width to use for defining your media queries, not the manufacturer's resolution.
The device pixel ratio of Samsung Galaxy Note20 is 2.625. Each CSS pixel is thus displayed by 2.625 physical pixels, requiring you to provide your images in 2.625x to keep them sharp.
The panel of Samsung Galaxy Note20 displays 1080 x 2400 physical pixels. This is the value reported by most analytics tools, while your CSS works on a viewport of 412 x 915 pixels.
4 other models share exactly the viewport of 412 x 915 pixels and the 2.625x density of Samsung Galaxy Note20: Google Pixel 8, OnePlus 8, OnePlus Nord, OnePlus Nord 2. A rendering validated on one is valid on all others.
Install the Mobile FIRST extension on Chrome, Firefox, or Edge, then select Samsung Galaxy Note20. Your page displays in a viewport of 412 x 915 pixels with the corresponding mobile User-Agent, in two clicks and for free.
DevTools resizes the window and applies partial emulation. Mobile FIRST additionally applies the User-Agent of Samsung Galaxy Note20, touch events, scroll behavior, and the actual appearance of the device, and allows capturing directly usable images and videos.
Yes. The extension works on any URL open in your browser, including localhost:3000, 127.0.0.1, or a password-protected pre-production environment.
No. The simulation covers the vast majority of development needs at no cost. A final test on a real device is still recommended before critical production deployment, but it's no longer necessary for each iteration.
A media query on the exact width targets Samsung Galaxy Note20: @media only screen and (min-width: 412px). Combine it with the pixel density to precisely target this model and those sharing its format.
