    Screen.width property discrepancy.

    I'm trying following simple JavaScript code:

    Code:
    alert(screen.width);
    On my Samsung A5(2017) smartphone. The specs for my device screen is `1080 x 1920` pixels while the alert reports me only `360` as `screen.width` value. My question is why there is such discrepancy between the vale of specs and the valeu returned by the code?

    Cell phones use variations of images depending on the resolution. You're device is registered as 360 @3x. You'll need to calculate the actual pixels by using screen.width * window.devicePixelRatio.
