I have tryed to connect my Samsung s8 to my Vauxhall insignear car and it won't connect it is trying but won't I tryed 3 other s8 phone they all connected is there anything in the phone that as to be on
Just the Bluetooth icon in the notification pulldown. (There are other things to do with some cars, but since you';ve already connected 3 other phones, I suppose you know the procedure.) About all I can suspect at this point, without actually doing it with your phone and your car, and seeing what happens, is that the phone is defective.
