Like most OEMs Samsung has a few special things on their Windows Phone devices, one of those things for Samsung is the Extra Settings app. This app controls the auto-display intensity, key vibration, and echo cancellation. We’d love to tell you what has been changed in version 1.7, but alas, there is no changelog. If you have a Focus S or Flash and you get this update let us know what you think changed.
