I'm about at my wit's end! This is the 2nd Era I've had and the 3rd Casio Commando...they all work fine--for a while--then the era drops out and won't connect with phone.....or is it the phone won't connect with the era? I don't know so I've tried replacing them both! I finally came to the conclusion that it's the phone--then, in the last couple of weeks, the era has started just going "dead". When I push the button and it says, "Waiting for phone to connect." I have to reboot phone to get it going again. But lately, I push the button and it says nothing.........nothing at all......and it's fully charged! I'm pulling my hair out because I need my hands to type or write or drive, not to hold a phone to my ear!
