I do not have any other blue tooth devices. In response to your suggestions. I have already checked these things and more. This is clearly a more intense issue, then what you have mentioned. This is ridiculous that your reply would even make sense at this point. Clearly, several, and I mean "several people " are experiencing this identical situation. From the many posts I have read, both on Verizon website, and Fitbit, the majority of people have a Samsung phone and Verizon service. Everyone has stated that this issue has stemed from an automatic update. It can't be that difficult to diagnosis this problem and fix it. My only conclusion at this point, is to go with another wireless carrier, get another phone that is not a Samsung, and never buy a Fitbit product again! This is really unacceptable!
