Android portrait keyboard pop up changing my orientation to landscape

Question

So i have a bug on andriod devices where the keyboard pops up during portrait mode and the background changes (taking the landscape media queries)

I am currently testing on 360x640 devices (HTC One, Samsung S4 etc)

I read here and other webistes to use (max-aspect-ratio: 13/9) for portrait and (min-aspect-ratio: 13/9) for landscape. However it is not working. This is my media queries for the portrait.

@media only screen

and (min-device-width:360px)

and (max-device-width:640px)

and (max-aspect-ratio: 13/9)

Someone please help me :)
