Why test your site on OPPO Find X3 PRO?

Curved edges

The screen of OPPO Find X3 PRO is curved on the sides. Content stuck to the edge is visually distorted, and the touch areas of the first pixels become difficult to reach.

Narrow viewport

With only 360 pixels wide, OPPO Find X3 PRO is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

4x density

Each CSS pixel of OPPO Find X3 PRO is rendered by 4 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

CSS viewport resolution of OPPO Find X3 PRO

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
  • 804 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 OPPO Find X3 PRO

4

The device pixel ratio of OPPO Find X3 PRO is 4.

In other words, a 1-pixel square in CSS occupies 4 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of OPPO Find X3 PRO

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

  • 1440 pixels in width
  • 3216 pixels in height
  • 20:9 Screen ratio

526 pixels per inch (ppi) · 6.7 inches diagonal, or 17 cm

const isHighDensity = window.devicePixelRatio >= 4;

Meta viewport tag

Essential for OPPO Find X3 PRO to use its CSS viewport and not a simulated width of 980 pixels.
