Thanks, that helped. I pressed and held the Bluetooth Icon. This brought up a popup menu that includes 'Unpair'. This is my first smartphone and so I am a complete novice. I appreciate the help.
My Samsung Galaxy Centura stopped connecting with my paired headset. When this happened on other phones, I simply deleted the paired device an then reaquired it. I cannot find how to delete the paired device. Am I overlooking some simple step?
