I can't go to settings to turn bluetooth on for new devices

I have a gear fit from a friend and need to change settings so my phone, "a new device," can find it. I cant get to the home screen to do this, it just gives instructions "to connect your gear fit first download gear fit manager" etc. I know how to connect the two once I can get to settings but it won't go off this instruction screen. It has not frozen as I can go on to the next screen where it says "in gear fit manager select the device you want it to connect to." I have rebooted 3 times but whenever it turns on it is on this message.
