I have doubled up calendar entries on my phone, but not in my Google Calendar. Anyone know of causes/fixes other than deleting manually?
Is there a different color bar on the left for each entry?
Mine does the double calendar entry because I have google calendar set to sync with my outlook calendar.
It is a different color for the different calendars.
Not quite sure if this ever got answered, but in case it didn't: I had the same issue with my phone. I had a lot of issues getting it figured out.
Open your calendar. Hit the menu button (I'm new to Android so I'm not sure if that's the name of the icon that looks like a page) and open the settings. There should be a "Calendars" option. Go there and disable the calendar that you don't want to show.
