Most of us are probably guilty of unintentionally creating duplicate contacts on our phones. For example, instead of updating an existing contact’s information, you just go ahead and create a new entry using the contact’s new number or email which leaves you with two contact entries for the same person with different contact info. This can be confusing, especially if you have no way to tell which information is most recent, unless you put a number on each contact such as Liz1, Liz2, and so on.

Another way to have duplicate contacts is when you recover and sync your contacts from a backup after resetting your device to factory settings or changing SIM cards. This can clutter your contact list and make it difficult for you to navigate through your contacts. Going through these duplicate contacts can be annoying and sometimes exhausting. Imagine having to scroll down multiple times just to get to the contact you want or trying to determine which version you saved last.

It is best to get rid of the duplicate contacts altogether to avoid confusion. You can either delete or merge them so that you are left with an organized contact list. Now, you can do this by manually going through each and every contact on your list and deleting the duplicate ones, but it is time-consuming and repetitive at the same time. Fortunately, there are easier and faster ways on how to remove duplicate contacts on Android.

Use Your Device’s Contacts App

Many Android devices come with a built-in feature that lets you delete or merge your contacts. You can use the Contacts app to scan all your contacts for duplicates and combine them.

  • Launch the Contacts app and tap the menu button.
  • Tap Settings > Merge duplicate contacts.
  • You will see a list of the duplicate contacts on your device.
  • Check the names you want to delete or merge.

  • This will show all of the contacts associated with your Gmail account, including those that have been saved on your Android phone.
