Also when they showing the model number the arrow is pointing up so I'm guessing that there is nothing that has been tampered with. The only setting when you go through the one through eight and then the numbers that has a downward-facing arrow is the one that looks like a b or a six with the right side of that Circle missing which is right before the L setting. Does everything sound correct? If so I guess I have a faulty dongle or a faulty unit? Posted from my SM-N910V using the RDF Mobile App!
