Android devices seem to maintain a history of connected devices for "easy connection" the next time you use them. Even if you delete them from the active connections list. You will need to go into the "Advanced" tab on your connections list, then click on "manage networks" and delete your gopro connection from there also.
After that go into your GoPro Hero 4 black settings menu and choose the "reset wifi" option (no need to reset the camera). Once that is done you just set up the GoPro in the app as a first time connection.
