To find out what version your Buzz is running and to update, if necessary, please make sure that your Buzz is on and already paired to your phone.
Launch the Neosensory app and tap the upper-left menu;
Select Your Buzz;
Your software (firmware) version will be listed below your band’s serial number.
Click on Update Device;
The app will either give you an option to update your band (if the automatic update toggle isn’t selected) or it will let you know that your band is up to date.
