A. 1. Ensure Bluetooth is enabled: Go to your device's Settings > Bluetooth and make sure it is turned on. 2. Restart both devices: Turn off your smartphone and the watch, then turn them back on. This can help reset the connection. 3. Re-pair the devices: In the Bluetooth settings, forget the DayBand watch and then re-pair it by selecting it from the list of available devices.

B. 4. Check for app permissions: Go to Settings > Apps > DayBand > Permissions and ensure that all necessary permissions (like location and Bluetooth) are granted.
