I have a Samsung Galaxy S3 phone that I use with my 550. I never setup a password. It uses the default password. I just got a Samsung Galaxy TabS that I would also like to use. The problem is that when I turn the tabS on it asks for a password and I don't have one. It also doesn't ask me to use the default password... therefore I can use the TabS for my black vue. I don't know the default password to enter it into the tabS screen. I also can't find any directions on how to reset my password on either device. This is the problems we all probably have when we set it up initially and don't have to do anything to it for a couple years. Can anyone help?
