Hey there! I have a few troubleshooting steps we can try to see if we can get the buds to connect properly.
The first thing I recommend is to reset the Galaxy buds, you can do so following these steps.
First, navigate to and open the Galaxy Wearable app on your phone.
For the Galaxy Buds or Buds+, tap About earbuds. Tap Reset earbuds, and then tap Reset to confirm.
If you are unable to connect after this, give these steps a try.
Go to Bluetooth menu and forget the device
Next, open the Wearables app and unpair the buds from the app
Once unpaired, uninstall and reinstall the Wearables app
Then reconnect the device to the phone like it was connecting for the first time
Another good thing to always check is to make sure the connections are free of debris or anything that would hinder the contacts from touching properly. You can use the following link for some good maintenance/ cleaning steps.
If after performing this and your symptoms still persist, send me a private message with your model code and serial number.
