I have paired many of my Bluetooth devices to the S21 with no problem but my omn neckband Bluetooth will not pair any ideas? I might mention that this is the worst phone I have ever had from Samsung the S8 was my absolute favorite
It could be that your OMN neckband is already paired with another device. If you connected it with another device, you have to go back into the other device you previously paired it with and manually remove the pairing from the other device's Bluetooth settings. Then it should show up on your new device's Bluetooth.
First you have to turn your Bluetooth on in the drop down menu of your device. Then turn your headphone's Bluetooth on. Once it's on and if it isn't previously paired with any other device, you should see it in your Bluetooth menu.
