The BONX earpiece icon at the upper right corner of the Home Screen shows connection status between your smartphone and BONX earpiece.
For Android devices, the icon next to smart phone's battery icon shows the BONX earpiece's remaining battery.

White: Connection successful
Red: The smartphone's Bluetooth is turned off or there is a problem with the connection

If the BONX earpiece is connected but the icon remains white or red, try reconnecting the smartphone and BONX earpiece.
