Conference call crusaders, Google Calendar just became your best friend. Through an update to the Google Calendar app on Android, passcodes can now be automatically added to conference phone numbers, decreasing your chances of punching an incorrect code and having to call back.
The passcodes are found by Google Calendar from the location or notes field in the calendar event you are calling from, so be sure that information is included going forward. If it is, a tap on the conference call number from within an event will ask if you want Google to call with or without the code. How handy.
