Changing a smartphone is always an exciting moment, but with it comes the routine task of transferring important information. The most critical element for most users is the phone book, the loss of which can be a real nightmare. Fortunately, the ecosystem Android offers many built-in tools and third-party solutions that allow you to complete this procedure in minutes without losing data quality.
In this article we will look in detail at how to transfer contacts from Android to Android using video instructions and text algorithms. We will consider both classic methods through cloud services and direct file transfer, which is especially important if there is no Internet or the need to transfer data to a device without a Google account.
Regardless of whether you change Samsung to Xiaomi or switch from a budget model to a flagship, the principles of working with the contact database remain similar. The main thing is to choose a method that guarantees the integrity of the information and the preservation of all additional fields, such as email addresses, notes and linked photos.
Synchronization through a Google account: the most reliable method
Using Google cloud storage is the de facto standard for Android users. This method does not require physical connection of devices and works automatically if both smartphones are logged into the same account. Synchronization provides instant database update: as soon as you add a number on the old phone, it appears on the new one.
To get started, you need to make sure that the option to save contacts is enabled on the original device to your Google account, not to your phone memory or SIM card. You can check this by going to Settings → Accounts → Google and making sure that the switch opposite the “Contacts” item is active. After this, the system will automatically upload all records to the company’s servers.
On a new smartphone, just enter your Gmail login and password. The system itself will offer to restore data from a backup copy. If automatic downloading does not start, you can force the process manually through the synchronization settings menu. This is the most secure option, eliminating the risk of file damage during transfer.
⚠️ Attention: Make sure that on your old phone the contacts are saved in your Google account. If they are in the memory of the device (“Phone”), synchronization will not work and the data will remain locally.
Before selling or transferring your old phone, be sure to complete full synchronization and check for contacts on contacts.google.com through a browser on your computer.
Export and import via VCF file: a universal solution
If using the cloud via For some reason it is impossible or inconvenient, an excellent alternative would be to create a backup file in the VCF (vCard) format. This format is supported by absolutely all modern operating systems and applications for working with address books, which makes it ideal for cross-platform exchange.
The file creation process takes a few seconds. You need to open the Contacts app, go to the management menu (usually three dots or bars in the corner) and select Manage Contacts or Import/Export. Next, select the “Export to VCF file” option, after which the system will offer to save the file to internal memory or to an SD card.
The resulting file contacts.vcf (or with a different name) must be transferred to a new device. This can be done via instant messengers, email or Bluetooth. On the receiving device, just click on the file, and the system will offer to import the records it contains into a local database or selected account.
- 📂 The VCF format saves not only numbers, but also names, photographs and addresses.
- 🔄 The file can be transferred an unlimited number of times to different people.
- 💾 File size with thousands of contacts usually does not exceed several megabytes.

Use of Bluetooth and Wi-Fi Direct for fast transfer
For those who prefer direct connection of devices without using intermediate files or the Internet, wireless communication technologies remain relevant. Bluetooth suitable for transferring small amounts of data, while Wi-Fi Direct provides high speed and stability when migrating large databases data.
When using Bluetooth, the process is as follows: visibility is turned on on both devices, pairing is performed, after which the “Send all contacts” option is selected through the contacts menu or specific entries are selected. However, this method can be slow if there are several thousand entries in the phone book.
A more advanced solution is to use the fast exchange functions built into manufacturers' shells. For example, Samsung Smart Switch, Xiaomi Mi Mover or Huawei Phone Clone. These applications create a direct, secure communication channel via Wi-Fi Direct, allowing you to transfer not only contacts, but also messages, call logs and system settings.
| Transfer method | Working speed | Internet requirement | Setting up complexity |
|---|---|---|---|
| Google Synchronization | High | Required | Low |
| VCF file (Bluetooth) | Low | Not required | Medium |
| Proprietary utilities (Wi-Fi Direct) | Very high | Not required | Low |
| SIM card | Medium | Not required | Low |
Data transfer via SIM card: the old proven method
Despite the development of cloud technologies, the transfer method via SIM card does not lose its relevance, especially when moving between devices of different ecosystems or in the absence of access to the network. This method is simple, but has significant limitations in the volume and quality of stored information.
To use this method, you need to go to the contacts application on your old phone, select the “Copy contacts” option and specify the source as the phone memory, and the destination as the SIM card. After copying is completed, the card is moved to a new smartphone, where the reverse operation is performed: import from SIM to the device memory or account.
It is important to understand that the SIM card has limited memory capacity and often (does not support) storing long names, multiple numbers for one contact, or photos. Therefore, it is better to use this method as a backup or to transfer only the most important numbers if other methods are not available.
⚠️ Attention: When copying to a SIM card, contact names may be trimmed to 10-15 characters, and additional fields (addresses, notes) will be permanently deleted.
Third-party applications for data migration
The store Google Play presents many specialized utilities developed by third-party vendors. Applications such as Copy My Data, SHAREit or Send Anywhereoften offer more flexible settings and cross-platform compatibility, allowing you to transfer data even between Android and iOS.
The principle of operation of such apps is usually based on creating a temporary Wi-Fi network between devices or using QR codes for pairing. The user just needs to install the application on both phones, select the type of data to be transferred (in our case, Contacts) and start the process. The interface of such apps is usually intuitive and contains visual cues.
Using third-party software makes sense if standard system tools fail or if you need to transfer data to a device with a very outdated version of Android, where modern synchronization protocols may not work correctly. However, you should be careful about the permissions that such applications request.
Why do standard methods sometimes not work?
Standard methods may not work due to a conflict between Android versions, the lack of Google services on the new device (for example, some Huawei models) or damage to the contacts database on the old phone. In such cases, third-party applications that work at the file system level are often more effective.
Solving synchronization problems and errors
During the data transfer process, users may encounter various errors, such as duplicate entries, missing parts of contacts, or synchronization failure messages. Duplicates often occur when importing the same VCF file multiple times or when multiple synchronization sources are running simultaneously.
To solve the problem of duplicates, modern versions of Android have a built-in merge function. In the Contacts application, you need to find the “Correction and Management” or “Merge Duplicates” option. The system will automatically analyze the database and offer to link records related to one person into a single profile.
If synchronization freezes or gives an error, try clearing the cache of the Google Play Services application and the Contacts application itself. It is also worth checking whether your account's cloud storage is full, as this may block the download of new data.
Regularly creating backup copies in VCF format and saving them on your computer or in the cloud is the best insurance against data loss in the event of any system failures.
Frequently asked questions (FAQ)
Is it possible to transfer contacts if the new phone does not yet have a SIM card?
Yes, of course. Most modern methods (Google Sync, Wi-Fi Direct, Bluetooth) work through the phone's wireless module and do not require an active SIM card or mobile network; a Wi-Fi connection or direct connection is sufficient.
What to do if contacts have been copied, but without photos?
Photos of contacts are often stored separately from the main database or linked to an account. When exporting to VCF, photos may not be saved if the appropriate option is not selected. The best way to save photos is to use synchronization through a Google account or proprietary utilities such as Smart Switch, which transfer the entire user profile.
Is it safe to use third-party applications to transfer contacts?
Applications from the official Google Play store undergo security checks. However, it is worth reading the requested permissions carefully. If a simple file transfer app requires access to your microphone, geolocation, and SMS, it's suspicious. It is better to use proven utilities with a high rating.
How to transfer contacts from a broken Android screen to a new one?
If the sensor does not work, but the phone turns on, you can try connecting a USB mouse via an OTG adapter to control the menu. If the screen is completely black, but the phone is responding, connecting to a computer and using USB debugging (if it was enabled previously) or removing the SIM card if the contacts were stored on it will help.
How long does it take to transfer 1000 contacts?
When using Google Sync or Wi-Fi Direct, the process takes from 30 seconds to 2 minutes depending on the speed Internet and processor power. Via Bluetooth, a transfer of this volume can take 5-10 minutes. Via a SIM card - about 1-2 minutes for writing and reading.
