If you're on android, read the messages in the popup status window, it'll leave it "unread" until you open the conversation. You might need to enable the preview function for popups and/or popups for out to work. Kind of works unless someone sends a massive amount of messages/text.
Sony switched over from Linux (ps3) to kfreebsd (ps4) due to licensing. Sure they (netflix) contribute back to FreeBSD, I don't doubt it, but don't act like licensing doesn't have anything to do with it.
> For the operating system, we use FreeBSD version 9.0. This was selected for its balance of stability and features, a strong development community and staff expertise.
...or due to the less restrictive licensing, it's ok netflix everybody does it...
