Does anyone know how I can get the notification sound to last longer, the notification light to stay on until I check the message, and for the top status bar to have an icon indicating that I got a new message? Right now I have a custom notification that lasts ~15 sec but it only plays ~5 sec of it. The light comes on when the message comes through, but after the notification is done playing so does the light and so does the notification on the top.
