@mandingoxx: To troubleshoot the issue, please start by pressing the Volume Down and Side buttons together for around 10 seconds until the phone restarts, as this will refresh the device and address any temporary issues. Don't worry, this won't affect your personal data or settings.
Now, head to Settings > Connections > Flight Mode, and toggle this off if applicable, followed by More connection settings > Nearby device scanning > On. You should also make sure that your device is up to date by heading to Settings > Software Update > Download and Install.
Following these steps, please head back to Settings > Connections > Bluetooth > On > Place a Bluetooth device in pairing mode by following the manufacturers instructions, and select it from the list of available devices to complete the connection. If you have previously established a connection with a device, then please tap the cog symbol to the right of it, select 'Unpair', toggle Bluetooth off, then on again, and run through the connection process once again. If the issue persists, you may wish to head to Settings > General management > Reset > Reset Wi-Fi and Bluetooth settings > Reset settings, however please be aware that this will remove any Wi-Fi networks and Bluetooth devices that you have previously registered to the phone.
