Ok , your welcome!Thanks for the quick response! However, that did not solve the problem. :-(
Att was one carrier didn't allow the slider to completely mute with volume buttons but try a app in galaxy Play store called Sound Assistant see if you can tweak it with that , yes notification toggle pretty quick also , your welcome!O.K., that works and is almost as easy as using the up-and-down volume buttons on the phone. But what I've just realized is that those buttons are completely dead...I also now can't use them to adjust the volume level of the ringer. Yikes. Is there an easy alternative way to adjust the volume level, and any thoughts on why those buttons would suddenly stop working? Thanks much.
