It seems that no matter what level I set my ring tone volume using the button on the side, when I get a text message, the notification is at the same level. What gives? Is there another place that notification volume can be set? I know you can select various sounds but, what about volume? Pain in the rear having this go off in my office. I want to know when I get a text but, don't need to announce it to the whole world. Any help is appreciated.
