Hi there, @John1329. Welcome to the Fitbit Community Forums. It's sad to hear that your Charge 4 won't connect to either of your phones. I appreciate you've taken the time to troubleshoot this issue prior to posting here, I'll do my best to help you with this.
In addition to the steps you've done so far, please try the steps below in the order listed:
- Unpair your Charge 4 from your phone's Bluetooth and Fitbit app.
- Unpair other Bluetooth devices that you may also have paired to your phone's Bluetooth settings.
- Force quit the Fitbit app.
- Turn off other Bluetooth connections when not in use. This can help to prevent connectivity issues or Bluetooth interference.
- Shut off your phone and turn it on after 1-2 minutes.
- Turn on the Bluetooth on your phone.
- Plug it into the charging cable and open the Fitbit app.
- Set up your Charge 4.
- If there is no connection, restart your Charge 4.
- Set up notifications again.
- Once your Charge 4 is paired and syncing, please proceed to set up your other Bluetooth devices to your phone again.
With the steps above, what I want you to do is to pair your Charge 4 first to your phone's Bluetooth settings before any other Bluetooth device is connected to your phone.
