Reasons Duplicate Calendar Events Created in Android

To start deleting the identical calendar from Android App. You must know the reasons for having repeated events. Below are the causes.

  • If you are seeing your duplicate calendar events only in your Android phone rather than in Google Calendar. This is caused by local calendar storage, cached data, or another calendar account syncing on your device.
  • The reason duplicate entries are visible is because of multiple calendars. Some users often create the same events in other calendar accounts. When multiple calendars are enabled, you will see the same entries twice or more.
  • A colleague or family member’s calendar is shared with you. You are also individually invited to the same events. That’s why you are seeing both entries.
  • Your main calendar contains a corrupted cache or syncing bugs that cause duplication.
  • Sometimes, external apps are not connected properly in the Phone calendar, which causes similar entries.

These are the factors that cause duplicate calendar items in Android. If you have difficulty finding the calendar events in Android. Follow the steps below.
