How to transfer contacts from Android to Android via computer: Complete guide

Changing a smartphone is always stressful, associated not so much with financial costs, but with the fear of losing important data. In the era of cloud technologies, we are accustomed to relying on automatic synchronization, but a situation often arises when there is no Internet, an account is blocked, or it is necessary to transfer data between completely different ecosystems, for example, from Xiaomi to Samsung. It is at such moments that the computer becomes an indispensable intermediary, allowing you to create a reliable local copy of the phone book.

Using a personal computer to backup contacts gives the user complete control over the process. You do not depend on the speed of Wi-Fi, the amount of cloud storage or the vagaries of synchronization. Local file, saved on your hard drive, ensures that even if Google or the manufacturer's servers are completely inoperable, your numbers will remain intact. This is especially true for business users, where the loss of one client is unacceptable.

In this article we will analyze in detail all existing methods of transferring data via a USB cable, consider working with various file formats and identify potential problems that you may encounter when changing vendors. You will learn not just to copy numbers, but also to structure them correctly, avoiding duplicates and loss of important fields, such as email addresses or positions.

Preparing the workplace and devices

Before taking active steps, you need to make sure that all system components are ready for operation. You will need the smartphone itself, a computer running Windows, macOS or Linux, and a working USB cable. It is advisable to use the original cable, since cheap analogues often only support charging and do not transmit data, which will lead to connection errors.

On a new device, it is also worth checking the free space and condition of the battery. The data transfer process, especially if there are thousands of contacts, can consume energy, although only slightly. It is important to unlock the phone screen when connecting to the PC for the first time so that the Android security system asks for permission to transfer files.

⚠️ Attention: If, when connecting the cable, the computer makes a device connection sound, but the smartphone does not appear in “My Computer,” try switching the USB cable to another port, preferably to a USB 2.0 connector or directly to the motherboard, bypassing USB hubs.

Make sure that the necessary drivers are installed on your computer. For Windows 10 and 11, they are usually installed automatically, but for older versions of the OS or specific brands, such as Huawei or OnePlus, you may need to install proprietary software or generic ADB drivers. Without this, the computer will only see the phone as a power source.

Export method through the built-in Contacts application

The most universal and reliable method, working on 99% of Android devices, - this is the use of standard export functionality. The interface may differ slightly depending on the manufacturer's shell (MIUI, One UI, ColorOS), but the logic of actions remains the same. You need to find the application responsible for storing numbers and select the export function.

Usually the path looks like this: open the Contacts app, find the menu (three dots or bars) and select Manage Contacts or Import/Export. The key here is the choice of source. The system may offer to copy data from the phone memory, SIM card or Google account. To create a full backup, select device memory or a specific account, if it is synchronized.

When choosing a file format, the system will offer to save the data as .vcf (vCard). This is a standard format that is supported by all modern operating systems. After clicking the Export button, you will be asked to select a save location. Select internal memory, create a “Backup” folder there and remember the file name.

After the process is completed, the file contacts.vcf (or a similar name) will appear in the phone's memory. Now, by connecting your smartphone to your computer in file transfer mode (MTP), you can copy this file to your hard drive. This is your insurance.

Working with VCF and CSV files on your computer

Once the contact file is on your computer, you can manage it. The format .vcf is convenient because it saves not only numbers, but also photographs, addresses, notes and additional telephone numbers. However, if you need to edit the list, sort it, or remove duplicates before transferring to a new phone, conversion or editing may be required.

For viewing and easy editing, you can use standard Windows applications such as People or Mail, which can open vCard files. If deep processing is required, for example, removing thousands of duplicates or changing the number format, the file can be converted to .csv (tabular format) and opened in Excel or LibreOffice Calc.

Option	VCF format (vCard)	CSV format	LDIF format
Purpose	Universal contact exchange	Tabular data, Excel	Email clients (Thunderbird). Software
Saving photos	Yes (built-in)	No (link only)	Partially
Editing	Difficult without special equipment. BY	Convenient in Excel	Difficult
Compatibility	Android, iOS, Windows, macOS	Office packages	Specific

When working with CSV files, be be extremely careful with encoding. If, after opening in Excel, you see “krakozyabry” instead of Russian letters, it means that the file needs to be saved with encoding UTF-8. Incorrect encoding will result in all names turning into an unreadable set of characters when imported to a new phone.

How to convert VCF to CSV online?

There are many services, for example, AConvert or specialized sites for vCard. Upload the file, select CSV format and download the result. However, if contacts contain confidential information, it is better to use offline converters or Excel so as not to transfer data to third parties.

If you plan mass editing, make sure that the columns in the table correspond to the standard fields: “Name”, “Last name”, “Phone”, “E-mail”. Changing the column headings may result in data ending up in the wrong cells during reverse import.

Importing contacts to a new Android smartphone

When the contacts file is prepared and transferred to the new device (just copy the file .vcf from the computer to the memory of the new phone via USB), the import stage begins. The logic is the opposite of export: we take data from a file and embed it in the phone book.

Open the Contacts app on your new device. From the menu, select “Import from file” or “Manage contacts” → “Import”. The system will prompt you to select a source - specify “Device memory” or “Internal storage”. Find the previously copied file contacts.vcf.

⚠️ Attention: When importing, the system will ask where to save the contacts: to the phone memory, to the SIM card or to a Google account. Highly recommended select a Google account. This will ensure automatic synchronization in the future, and the next time you change your phone, you won't need a computer.

Once you select a destination, the copying process will begin. If the file contains duplicate numbers that are already in the memory of the new phone, the Android system will offer options: skip, create a duplicate, or merge. It is recommended to select merging to save call history and linking to instant messengers.

After completing the procedure, check a few contacts selectively. Make sure you have photos, correct number formats (especially area codes), and additional fields. If everything is in order, the old backup file can be left on the computer as an archive copy.

Using cloud services and desktop clients

Although direct file transfer is reliable, many users prefer to use ecosystem tools. For Google account holders, the easiest way is the web interface Google Contacts. By connecting your phone to Wi-Fi, you can go to the site contacts.google.com from your computer, import a file there .vcf, and the contacts will automatically appear on the phone after synchronization.

For users Samsung there is a app Samsung Smart Switch for PC. It allows you not only to transfer contacts, but also to create complete system backups, including messages, settings and icon locations. This is a deeper level of working with data, which requires the installation of special software on the computer.

Other manufacturers have similar solutions: Xiaomi PC Suite (although support for older versions is being discontinued, new analogues are built into the ecosystem), HiSuite for Huawei. These apps often require enabling USB debugging mode, which can be difficult for the average user, but provides advanced capabilities.

The advantage of cloud-based methods and proprietary software is that they can often automatically recognize duplicates and merge theirs are smarter than stock Android imports. In addition, they can transfer contacts along with links to specific applications, for example, profiles in Viber or WhatsApp (although instant messengers often require a separate backup).

Solving problems: duplicates, encoding and errors

In the process of transferring data through a computer, users often encounter technical nuances. The most common problem is the appearance of contacts with the same names or strange symbols instead of letters. This can be solved by choosing the right encoding when converting files, as mentioned earlier.

Another common problem is a disconnection when transferring a large file. If the process is interrupted midway, the file may be damaged. In this case, try dividing a large contacts file into several smaller parts (for example, in alphabetical order A-K and L-Z) and importing them one by one. This will also make it easier to find errors if they occur.

Sometimes contacts are imported but do not appear in the call list. Check your display settings in the Contacts app. There may be a filter “Only contacts from phone”, and you imported them into your Google account, or vice versa. Change the filter to “All contacts.”

⚠️ Attention: Android shell interfaces (MIUI, One UI, ColorOS) are constantly updated. The location of menu items may vary. If you do not find the described function, use the search inside the phone settings for the word “Import” or “Export”.

If none of the methods work and the phone does not see the file .vcf, try a third-party contact manager application from the Google Play Store, for example, “Copy My Data” or “Contact Editor”. They often have more flexible tools for working with files on a computer and can correct errors in the file structure before importing.

Is it possible to transfer contacts if the screen of an old phone is broken?

Yes, it is possible, but it is more difficult. If USB debugging is working and the phone is detected by the computer, you can use ADB commands to upload the contact database. If the screen does not respond, but there is an image (via an HDMI adapter), you can connect a mouse and control the phone. As a last resort, remove the SIM card (if contacts were stored on it) or use the cloud if synchronization was enabled earlier.

What to do if photos of contacts disappeared during import?

Photos are stored inside the file .vcf in encrypted form. They are often lost when converted to CSV. Make sure you are using the VCF format for transfer. Also, some phones do not know how to “link” photos from a file during bulk import. In this case, only synchronization through a Google account will help, which handles media attachments better.

Is it safe to transfer a contacts file through a public computer?

Strongly not recommended. The contacts file contains personal data. There may be keyloggers or viruses on a public PC that will copy the file. Use only personal, trusted devices or secure connections.

How to merge contacts from multiple VCF files?

Simply copy multiple files .vcf to one folder on the computer. Select them all, right-click and select "Merge" (if supported by OS) or use online services to merge vCard files. In Windows, you can open them through the Contacts application, which itself will offer to add all entries from the selected files.

Why are contacts from a new phone not synchronized with Google?

Check whether synchronization is enabled in the Google account settings on your phone. Make sure that when saving you select your Google account and not “Phone” or “SIM”. Also check the availability of free space in your Google Account (the contact limit is usually 25,000, which is rarely achieved, but the 15 GB storage limit may be exhausted by photos and documents).
