How to transfer contacts from Android to Android: a complete guide

Changing a smartphone is always stressful, but the most painful moment is often not the device itself, but the fear of losing important information. First of all, we are talking about the phone book, where the numbers of colleagues, friends and emergency services are stored. Fortunately, the ecosystem Android offers many built-in and third-party solutions to solve this problem in a few clicks.

In this article, we will take a detailed look at all the current methods available to users in 2026. From classic cloud synchronization to manual file export, you'll find out which method is best for your situation. Whether you're moving to a new flagship or recovering data after a reset, it's easier than ever. The main thing is to choose the right tool and strictly follow the algorithm of actions to avoid duplicating records or losing numbers.

Whether you're moving to a new flagship or recovering data after a reset, contact migration has become easier than ever. The main thing is to choose the right tool and strictly follow the algorithm of actions to avoid duplicating records or losing numbers.

Synchronization through a Google account: the most reliable method

Using Google cloud storage is the “gold standard” for Android users. This method requires no wires and works automatically if you have configured your old phone correctly. The entire phone book is saved on the corporation's servers and instantly becomes available on any device after logging in.

First, make sure that synchronization is enabled on your old smartphone. Log in Settings → Accounts → Google and check whether the switch opposite the item Contactis active. If the checkbox is checked, the system has already sent your data to the cloud.

On the new device, just enter the same login and password for your Google account. The system itself will offer to restore data from a backup copy. However, if automatic recovery does not work, you can force the process manually through the synchronization settings.

• 🔄 Open Settings and find the section Users and accounts.
• ☁️ Select your Google account from the list and click Sync account.
• ✅ Make sure that the slider opposite the item Contact is turned on (highlighted in blue or green).

After completing these steps, open the application "Contacts" on a new phone. Wait a few minutes for the servers to process the request and a list of numbers should appear automatically. This method is ideal because it also saves profile photos and additional notes.

⚠️ Attention: If you have multiple Google accounts, make sure you sync the one with your main contacts. Users often confuse work and personal emails, which leads to an empty phone book.

Transfer via Bluetooth: work without the Internet

What to do if there is no Wi-Fi at hand or the mobile data is unstable? Technology Bluetoothcomes to the rescue. This method allows you to transfer a contacts file directly from your old device to a new one using a direct wireless connection.

The process begins by exporting the data to a file format .vcf (vCard). On an old smartphone, open the Contacts application, call up the menu (usually three dots in the corner) and select Manage contacts or Import/export. Next, click Export to .vcf file.

After creating the file, the system will prompt you to select a sending method. Select Bluetooth from the list of available applications. On the receiving device, you must turn on Bluetooth in the notification shade and confirm the request to receive the file.

Path to the file after receiving: Internal memory → Downloads → contacts.vcf

When the file is transferred, click on the notification that the download is complete or find the file through Explorer. The system will automatically offer to import the found entries into the phone book of the new device. This method is especially convenient when transferring a small number of numbers.

Using a SIM card as an intermediate carrier

Although this method is considered obsolete due to limitations in memory capacity and the quality of data storage (long numbers and photos are often lost), it remains universal. SIM card works as a physical key that can be used just move from one phone to another.

First you need to copy the data from the old phone's memory to the chip. In the Contacts app, find Settings and select Copy from phone to SIM card. The system will warn about the possible loss of some information if there are too many numbers.

After copying is completed, turn off both phones, remove the tray and move the SIM card to the new device. After turning on, go to the contacts application, select the import menu and click Copy from SIM card to phone.

Option	Phone memory	SIM card	Google Account
Record limit	No restrictions	Usually 250-500	No restrictions
Saving photos	Yes	No	Yes
Number length	Any	Limited	Any
Additional. fields	Email, Address	Name and number only	All fields

Use this method only in extreme cases when other methods are not available. For modern smartphones with thousands of contacts in the address book, transferring via a SIM card can be too time-consuming and incomplete.

⚠️ Attention: Before copying to a SIM card, be sure to check whether you have contacts with numbers starting not with +7 or 8, but with international codes. Old chips can cut off such numbers, making them non-working.

Applications from smartphone manufacturers

Large brands understand the importance of a seamless transition for customers, so they develop their own utilities. These applications often work faster than standard Android tools, as they are optimized for specific hardware and firmware. For example, owners use an application that transmits not only contacts, but also the desktop layout, alarm clocks and Wi-Fi settings. Users

For example, owners Samsung use the application Smart Switch, which transmits not only contacts, but also desktop layout, alarms and Wi-Fi settings. Users Xiaomi can use the built-in tool Mi Mover, and fans Huawei can use the utility Phone Clone.

Usually the process looks like this: you install the application on both phones (on the new one it is often pre-installed), scan the QR code to create a pair and select the data type for transfers. The transmission speed is significantly higher than that of Bluetooth.

• 📱 Samsung: Smart Switch application (available in the Galaxy Store and Play Market).
• 🌾 Xiaomi/Redmi: Built-in Mi Mover application in the "Tools" section.
• 🌸 Huawei/Honor: Phone Clone utility for quick data migration.

The main advantage of such solutions is the ability to transfer data even between different versions of Android, if both devices belong to the same brand or support a cross-platform transfer protocol.

What to do if the manufacturer's application does not see the second phone?

Make sure that both devices are connected to the same Wi-Fi network or that one of them has an access point enabled. Also check permissions: the app needs access to contacts and storage. Sometimes disabling the power saving mode on both smartphones helps.

Manual export and import via .vcf file

This method gives the user full control over the process and creates a physical copy of the database that can be stored on a computer or flash drive. The file .vcf is a universal standard that opens on any operating system.

Export contacts on your old phone as described in the section about Bluetooth, but save the file to internal memory. Then connect your phone to your computer via a USB cable or use a file manager to send the file to your email or instant messenger (Telegram, WhatsApp).

Download this file on your new device. When you click on it, the Android system will recognize the format and prompt you to select an application to import. Select “Contacts” or “Phone” and indicate where exactly to save the entries: to the device memory or to a Google account.

Recommended saving path: Google Account (for automatic synchronization in the future)

This is a great way to create a backup copy before selling your old phone. You can save the file to your computer and be sure that even if there are failures in the cloud, you will still have an up-to-date version of the phone book.

Solving problems with duplicates and merges

After transferring contacts, users often encounter an unpleasant situation: the same person is recorded several times. This happens when data is imported from both the SIM card, Google, and the phone's memory at the same time.

Modern versions of Android have built-in cleaning tools. Go to the Contacts application, open the menu and find the item Manage contacts or Settings. There should be an option Merge duplicates.

The system will analyze the database, find records with the same names or numbers and offer to merge them. You can choose to accept automatic merging or check each pair manually to avoid losing important notes.

⚠️ Attention: Before mass merging duplicates, it is highly recommended that you export all contacts to a .vcf file. If the algorithm does not work correctly and deletes the necessary data, you can restore it from a backup.

It is also worth checking whether contacts are saved in different languages ​​(for example, the name is in Russian and in English). In this case, automatic merging may not work, and you will have to edit the records manually, deleting unnecessary ones.

Frequently asked questions (FAQ)

Can I transfer contacts if the screen of your old phone is broken?

Yes, it is possible, but it is more difficult. If the sensor partially works, try connecting a USB mouse via an OTG adapter. If the screen is completely black but the phone turns on, connect it to the computer and try copying the contacts database file through a file manager, although on modern versions of Android access to system files may be denied without root access. The best option in this case is to log into your Google account through a browser on your computer and export contacts from there.

Why, after transfer, are the contacts displayed without names, only numbers?

Most often this happens because the contacts were saved to a SIM card that does not support storing names in UTF-8 encoding or has a limit on the length of the name. The problem could also be that you imported the .vcf file but did not select the correct encoding. Try opening the file on your computer and checking its contents.

How long does it take to synchronize 1000 contacts?

When using a Google account and a stable Internet connection, the process takes from 1 to 5 minutes. Most of the time is spent not on data transfer (the text weighs very little), but on processing by the server and loading the application interface on the new phone. Via Bluetooth, a transfer of this volume can take 10-20 minutes.

Is it safe to use third-party applications for transfer?

Use only proven applications from the official Google Play store with a high rating and a large number of downloads. Avoid apps that require suspicious permissions, such as SMS or microphone access, if their function is only to transfer contacts. Official utilities from smartphone manufacturers are always safer.
