Media queries in email and Android 5.1+

I'm trying to use a very simple media query, but looks like I'm missing something. My code seems to work in most clients, but when testing in litmus, from and above Android 5.1 I see that my media query is ignored.

I tried to make the most basic example, which can be found here: http://ift.tt/2lc2I8Z

Any idea what I might be doing wrong, or how else to achieve to target these android devices with specific styles?
