Why test your site on Samsung Galaxy S8+?
4x density
Each CSS pixel of Samsung Galaxy S8+ is rendered by 4 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.
Older hardware
The hardware of Samsung Galaxy S8+ dates from 2017. Its processor makes costly animations, heavy scripts, and display times visible that recent devices mask.
CSS viewport resolution of Samsung Galaxy S8+
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
- 740 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.
