Please direct all complaints to Special:Contact/feedback. It really should be Special:Contact/bug (you can use that too), but we'll pretend it is an oversight. It is not meant to be an exact 1:1 preview. That is actually impossible because there are possibly more than a dozen different form factors for mobile. For example, how exactly would it preview the way it shows on a Google Glass mobile device, or a dual-screen device?

It would also have to account for custom widgets and apps that users install that may alter the screen.

Ultimately, since this is a portable tool, it should work on most relatively recent mobile devices. If it doesn't then it is either a bug, something that will still be developed, or simply a device that isn't supported.

P.S. At least using the chrome developer tools you can actually simulate the screen size of a mobile device, so it does help somewhat.
