The 412 x 914 pixels viewport of Samsung Galaxy A71 rarely matches the round breakpoints of frameworks. It is precisely between these values that layouts break.
CSS viewport resolution of Samsung Galaxy A71
This resolution is what your stylesheet actually manipulates. It determines the applied breakpoint, the number of displayed columns, and the size of your images.
- 412 pixels in width
- 914 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.
