Hi there! I understand how frustrating it can be when your DayBand won't connect to your LG L45DL20s. Let's work together to figure this out!

First, could you please provide a bit more detail? Are you having trouble with the initial setup, or has it connected before and now isn't working? Also, are you able to see the DayBand in your Bluetooth settings?

In the meantime, here are some initial troubleshooting steps we can try:

1. Restart Your Phone: Sometimes a simple restart can resolve minor glitches. Go ahead and restart your LG phone, then try to reconnect the DayBand.

2. Check Bluetooth Settings: Ensure that Bluetooth is enabled on your phone. Go to Settings > Bluetooth and make sure it’s switched on. If your DayBand appears in the list of devices, try forgetting it (if it’s listed) and then attempt to reconnect.

3. Reset the DayBand: If the device was connected before, you might want to reset the DayBand. Look into its settings (usually accessed by holding down a button on the band) and find the option to reset or disconnect.

4. Update Your App: Make sure you have the latest version of the DayBand app installed from the Play Store. If there is an update available, install it and try reconnecting.

5. Check for Device Compatibility: Ensure your DayBand is compatible with your LG L45DL20s. Sometimes, specific models can have connectivity issues.

If these steps don't resolve the issue, I can look up more targeted solutions for you. Just let me know!
