Thanks Matt. I had already done that. I think the screenshot shows it (assuming it uploaded correctly). Anyhow, I think I figured it out.... it's TouchWiz. If I'm inside any app and the scene comes on, it's landscape. If the TouchWiz UI is in the foreground it's locked to portrait and then it forces the overlay to portrait. I know I can use one of the rotation apps (like Rotation Anywhere) to force TouchWiz to auto rotate but not sure if that's the behavior I want since the interface looks odd in landscape mode. Alternatively, I could use a different window manager such as Nova (I used to use it on my previous phone) but not sure I want to replace TouchWiz since I like it. I'm not sure if changing the scene type from overlay to dialog, etc would change the behavior but I'll experiment to see.
