Changing a mobile device often causes concern among users, especially when it comes to maintaining a personal phone book. Losing important numbers of colleagues, friends or delivery services can become a serious problem that disrupts the usual rhythm of life. Fortunately, the ecosystem Android and proprietary tools Samsung offer many reliable ways to migrate data without the risk of losing it.
In this article we will analyze in detail all the current methods for transferring contact information between smartphones. You will learn how to use cloud services for automatic synchronization, how to use a specialized application Smart Switch to completely clone a device, and how to manually export via files or SIM-card in emergency cases.
Regardless of whether you are switching from an old one Android-smartphone to a new flagship Galaxy or just want to create a backup copy, the instructions below will help you complete the process quickly and safely. We will look at the nuances of each method so that you can choose the most suitable one for your situation.
Synchronization through a Google account: the most reliable method
Using cloud storage Google is the most preferred way to save contacts for owners of devices based on Android. This method ensures that your numbers will be available not only on the new phone, but also through the web interface if the gadget is lost. To get started, you need to make sure that synchronization is enabled on your old device.
Go to the phone settings and find the section Accounts and archiving or simply Users and accounts. Select your profile Google and make sure that the switch opposite the item Contact is activated. If synchronization has been disabled, turn it on and click the button Synchronize to immediately send data to the server.
On the new smartphone Samsung just enter the same login and password for your account Google during the initial setup or add an account later through the settings menu. The system will automatically pull all saved numbers into the device's phone book within a few minutes if there is an Internet connection.
It is important to understand the difference between local storage and cloud storage. If contacts are saved only in the phone memory without being linked to an account, they will not be protected from system failure.
⚠️ Attention: Make sure that the contacts are saved in your Google account and not in the phone memory or SIM card, otherwise synchronization will not occur. You can check this by opening the Contacts application and going to the display settings.
This approach allows you to manage your call list remotely. You can delete duplicates or edit numbers directly through the browser on your computer, and the changes will be instantly reflected on your smartphone.
Periodically visit contacts.google.com to check the relevance of the backup copy and clear the list of duplicates using the built-in tool.
Using the Samsung Smart Switch application for a complete transfer
Proprietary utility Smart Switch designed specifically for equipment owners Samsung and allows you to transfer not only contacts, but also photos, messages, settings and even the home screen layout. This is an ideal option when switching to a new phone of the same brand, since the process is as automated as possible.
To get started, install the application Smart Switch on both devices, if it is not pre-installed (on new models Galaxy it is by default). Launch the app on both phones. On the old device, select the role Sender, and on the new one - Recipient.
Next you need to select the connection method. The fastest option is to use USB cable, which is often included with new smartphones. If there is no cable, you can use a wireless connection Wi-Fi Direct, although the transfer speed will be lower.
After the connection is established, the system will scan the contents of the old phone. You will be asked to select the data types to migrate. Make sure that the checkbox is opposite the item Contact, and also select other necessary data.
- 📱 Wireless mode convenient because it does not require additional accessories, but depends on the battery charge.
- 🔌 Cable connection provides maximum speed and stability, ideal for large volumes data.
- ☁️ Backup copy can be created on a memory card or in the cloud for subsequent restoration.
The copying process can take from several minutes to an hour depending on the amount of information. It is strictly not recommended to interrupt the connection, as this can lead to damage to the database files.
☑️ Preparing for Smart Switch operation
Export and import via vCard file (.vcf)
Method for creating a business card file (.vcf) is universal and does not depend on the phone brand or the availability of an Internet connection at the time of transmission. This method is especially useful if you need to transfer contacts to a device of another operating system or transfer them via instant messenger.
Open the application Contact on your old smartphone. Click on the menu (three horizontal stripes or dots) and select Manage contacts or Settings. Find the option Export contacts.
The system will prompt you to select a location to save the file. It is recommended to save it to internal memory or to a card microSD. After the export is complete, you will have a file with the extension .vcfcontaining the entire phone book.
Transfer this file to the new phone in any convenient way: via Bluetooth, instant messengers (Telegram, WhatsApp), email, or simply by copying a memory card. On the new device, open the file and confirm the import.
Settings → Contacts → Import/Export → Import from .vcf fileWhen importing, the system will ask where to save the numbers: to a Google account, to a phone or to a SIM card. Selecting a Google account will ensure further automatic synchronization.
What to do if the file does not open?
If, when you click on the .vcf file, the phone prompts you to select an application, select “Contacts” or “Contact Storage”. If the file is damaged, try opening it on your computer using a text editor to check the contents.
Transferring contacts via SIM card
Moving the phone book to SIM-card is an old but still working method that does not require the Internet or complex settings. However, it has significant limitations on the volume and quality of stored information.
In the application Contact go to the control menu and select Import/Export contacts. Click Export and specify SIM cardas the target storage. The phone will warn you about possible format restrictions.
After copying, move the SIMcard to a new one smartphone Samsung. Go to the contacts application of the new device, select Import/Export and specify Import from SIM card. Select an account to save.
| Characteristics | SIM card | Google account | vCard file |
|---|---|---|---|
| Number limit | 250-500 pcs. | No restrictions | No restrictions |
| Saving photos | No | Yes | Yes |
| Add. fields (email) | No | Yes | Yes |
| Network dependence | Not required | Required | Not required |
The main disadvantage of this method is the truncation of long names and the loss of additional data such as email addresses, birthdays and photographs of subscribers. SIM card stores only the name and main number.
⚠️ Attention: Before exporting to a SIM card, make sure that the contact names are not too long, otherwise they will be cut off. Also check the free space on the SIM card itself, as older cards may have a small amount of memory.
Use this method only as a temporary solution or in emergency cases when other methods are not available. For permanent storage, cloud technologies are preferable.
Data transfer via Bluetooth and Nearby Share
Technology Bluetooth remains relevant for transferring small amounts of data between nearby devices. In modern smartphones Samsung it has evolved into a function Nearby Share (Fast sending), which works faster and more convenient than classic pairing.
To transfer via classic Bluetooth open contacts, highlight the desired numbers or select the "Send all" option. In the list of sending methods, select Bluetooth. Discovery must be enabled on the receiving device.
The feature Nearby Share uses a combination of Bluetooth and Wi-Fi for high-speed transmission. Make sure that Bluetooth, Geolocation and the Quick send function in the notification shade are turned on on both phones.
Select contacts, press the button Share and find the name of the new device in the list of available ones. After confirmation on the receiving side, the file will be transferred and automatically prompted to save it to the phone book.
This method is good for its autonomy: it does not require the Internet, registration in services or cables. However, the transfer speed of a large list of contacts may be slower than cloud-based methods.
Using Nearby Share is preferable to classic Bluetooth, as it provides higher speeds and does not require manual pairing of devices.
Eliminating problems and duplicates after migration
After data migration is complete, users often encounter the problem of duplicate entries, when the same contact is displayed several times. This happens when data from different sources is merged, for example, from a SIM card and from a Google account.
Smartphones Samsung have a built-in tool to solve this problem. Open the application Contact, click on the menu and select Contact management. Find the item Merge duplicates.
The system will automatically find duplicate entries and offer to merge them. You can do this in bulk for all found pairs, or view each group individually to manually choose what information to save.
It's also worth checking the contact display. Sometimes new numbers are not visible in the call list. Go to the contact display settings and make sure that the checkbox next to All contacts or the correct account for display is selected.
- 🔍 Search for duplicates helps clear the phone book of garbage accumulated over years of use.
- 👁️ Setting the display solves the problem of "disappearing" numbers after changing the device.
- 🗑️ Deleting old entries from the SIM card is recommended after successful import to avoid confusion in the future.
Regular Cleaning up the phone book improves search performance and makes the interface cleaner. Do not neglect this procedure immediately after transferring data.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version of the One UI shell and the model of your Samsung smartphone. If you do not find the specified option, use the search in the settings.
Frequently asked questions (FAQ)
