I suspect there might be a bug here, but you worked it around by relying on the property, so it should be correct in the end. > > But, here I have one more issue.

As per > GonkDisplayJB.cpp it should have to be 720x1280. I think you are getting mislead by https://bugzilla.mozilla.org/show_bug.cgi?id=933170 360x640 is the Gecko CSS pixel resolution and seems to be correct. > > How could that be possible?
