the zoom factor to have the 680 pixel width layout over the full display width.
This is up to 1020 * pixel device ratio, above this, the layout changes to the format for common notebook/desktop displays.
When I test it on my notebook with 1368x768 display, Chrome, Windows 8, everything works fine, when i resize the window.
But on my Huawei Ascend P6, the zoom factor seems to be false, even more annoying, it's different false on each used browser.
Landscape shows 640 x 360 and device pixel ratio 2.
So what's wrong, that on desktop, the zoom factor works correct, but not on mobile?
