So I was in route from Texas to Michigan and had Google Navigation running on landscape. I turn off the screen and just let the Navi run in the background until I hear the verbal instructions, then I turn it back on for visual. Anyway, while it was asleep, I received a calendar notification. When I dismissed it, at first I seen a landscape version of my homescreen for about 10 seconds (not rooted, couldn't get a screenshot of that though). When I picked it up to look at it, I turned the phone upright and I got this screen until I put asleep and turned back on, then it went back to my normal homescreen. What happened? Anyone else ever seen this?
