this is a very specific glitch and i'm only bringing it up because i haven't found a way to turn off 'google now.' i don't use google now i wouldn't mind turning it off.
so the glitch occurs when
i get a text pushed to notification
i access the text message from the pushed notification (i am using the factory text message app)
i go into landscape mode (doesn't matter if i type or not), basically i take the text message app window that is superimposed over the desktop and turn it landscape
i press the back button to go back to desk top (doesn't matter if i send a text message or not)
the google now window will pop up for no reason.
i initially thought this might be some sort of delayed press of the google now bar underneath the superimposed window since the soft back button would be right on top of where the google now bar would be underneath. but this glitch manifests in both landscape orientations.
