How to delete the Android phonebook

Why duplicate contacts in Android and how to fix it?

The reasons for duplicate numbers in the phone book with the Android operating system can be several. These failures can be associated with a firmware change in the operating system, when backing up, as well as the re-synchronization of contacts from the SIM card or other sources. For example, very often duplicates appear when installing WhatsApp and other applications where you can add subscribers. Sometimes the problem lies in the fact that the user has several SIM cards in the phone, and therefore they are copied from several sources to the memory of the device at once.

If you encounter such a problem, you should not panic. As a rule, it can be solved in several ways, and there is no need to spend a lot of time or carry your phone to the service center and pay money. The whole process takes a few minutes and does not require any serious skills from you.

Merging contacts on Android

Before proceeding to the procedure of deleting records, you can try to merge them. The idea is that the system will automatically reconcile your contacts, and if it detects that they are identical, it will merge them. In the end, all the duplicates will simply disappear and your smartphone will be left with the original copies. You can do this with the standard Android tools:

  • Go to “Contacts” application on your phone and tap the menu item or in any free area to bring up an additional menu (we look at the example of Xiaomi);
  • Go to “Merge duplicates” and click “Merge”;

  • The system automatically scans your entire list and shows you which contacts can be merged. You simply select all or merge only the ones you want.

Merging contacts via Gmail

With the Android operating system, each user creates an account that automatically links to your Gmail service. Through it, you can also view a complete list of duplicates and delete the ones you don’t need, and the system will do it automatically. The whole process boils down to the following steps:

  • On your computer, go to the Gmail site and sign in with the same account that you have on your smartphone;
  • Go to “Contacts” (depending on the selected interface, the tab on the right or left side of the site);
  • Find item “Similar contacts”. Click on it and press “Merge” to have the system automatically delete duplicates. You need to have synchronization set up on your smartphone, so that the information on the site is as updated as possible, and once you have deleted the duplicates, it will be updated on your phone as well.

Delete contacts in manual mode

If you have few duplicates, you can delete them manually, using the standard tools on your phone.

  • Go to “Contacts” and choose the necessary one from the list;
  • Tap on it and press “Delete” in additional menu;
  • This way you delete all those records which are duplicated, leaving one copy at a time. The information is usually displayed in alphabetical order, so on your phone screen you will see all the duplicates one by one.

Attention! Android also has a “Group Delete” option, which allows you to mark all the contacts you need and delete them all at once. The process is also performed in the additional “Contacts” menu.

Deactivating the account

If you want to completely reset your contact list, you must disable the account with which they are synced. This option will be useful if you are preparing the phone for sale or on the contrary have bought a smartphone and want to get rid of other people’s numbers.

Thus, you will get rid of the display in your phonebook numbers of social network users who are your friends, and you will not have to search for the necessary numbers among the data of unfamiliar people with whom you communicate by means of messaging in any of the popular messengers.

Editing the synchronized Google data

If you duplicate the list of contacts in your Google account, you can not only delete it entirely, but also edit it and then synchronize your device with your account. This is handy if you have a lot of numbers in your address book, and you don’t know how to delete a phone number from your account without disabling it. Follow the instructions:

You can synchronize almost anything:

In most cases, saving data to the cloud is the responsibility of your Google account, but smartphone manufacturers themselves often initiate a similar procedure with their cloud storages. In addition, there are several special applications that also provide similar services.

However, remember that the synchronization function is very useful. if your phone is damaged or lost, you can easily and effortlessly restore the necessary data. Therefore it should be turned off with caution, and better temporarily.

How to fix the situation with the data synchronization and delete files from your smartphone forever

If you need to delete data to free up memory or for any other reasons, you only need to get rid of the reason for restoring the information. Synchronizing data is just a feature that can be turned off. You only need to determine which program or application is responsible for.
