A. Check the app settings to see if there is an option to adjust alarm settings. Go to the 'Settings' menu in the FreeStyle Libre 2 app, look for 'Alarms' or 'Notifications', and see if you can change the alarm behavior. If there is no option to silence alarms, consider using 'Do Not Disturb' mode on your Android device to temporarily silence all notifications from the app.
B. If the alarms are too loud, you can try lowering the overall volume of your device. Go to 'Settings' > 'Sound' > 'Volume' and adjust the media volume to a lower level. This may help reduce the alarm volume.
