@jimmybob: Apologies for the delay in responding to your query. Are you making sure to stay within Bluetooth connection range (around 10m)? Which speaker do you have, and have you tried connecting it to another compatible phone to see if the issue persists? Also, head into Settings > Apps > 3 dots (top right) > Show System Apps > Bluetooth Share / Bluetooth Test > Storage > Clear cache / data. If this doesn't help, go into your Bluetooth settings, select the device you are having problems with and then tap "Forget" or “Unpair” from that device and then restart your phone. If the problem persists then run the hardware test: Samsung Members app > Get Help > Interactive Checks > Run through the Bluetooth test.
