Changing a smartphone, especially switching to a modern line Samsung Galaxy, is always accompanied by the need for quick and reliable transfer of personal data. Among all the information stored on the device, contacts are perhaps the most critical resource - the loss of numbers can paralyze business and personal communication. Modern Android ecosystems offer many tools for migration, but it is important for the user to choose the most secure and effective method specifically for his situation.
The process of copying a phone book depends on the versions of operating systems, the availability of an account Google and the physical availability of both devices. You can use cloud technologies for automatic synchronization, specialized software from the manufacturer, or classic methods using a SIM card. In this article, we will analyze each method in detail so that you can transfer contacts transfer contacts without losses or duplicates.
It is important to understand that before starting any procedure, you need to make sure that the battery is sufficiently charged on both devices. Interrupting the data transfer process may damage files or create broken phonebook entries. We will look at both standard solutions and the nuances of working with backup files.
Synchronization via Google account: the simplest method
The most universal and recommended way to migrate data is to use cloud storage Google Contacts. This method does not require cables or installation of additional software, since the service is integrated directly into Android operating system. If your old device is already signed into a Google account, then most likely your contacts are already saved in the cloud without your knowledge.
First, you need to check the synchronization settings on your old phone. Go to the section Settings → Accounts and archiving → Account management. Select your Google profile and make sure the switch next to Contacts is turned on. If synchronization has been disabled, turn it on and click the "Synchronize Now" button to force the data to be sent to the corporation's servers.
Once the data is in the cloud, the restoration process on a new one Samsung Galaxy takes a matter of minutes. When you set up your new device for the first time, you will be asked to enter your Google account information. As soon as you log in, the system will automatically pull all saved numbers, photos and additional fields from the cloud into the local memory of the phone.
⚠️ Attention: Make sure that on your old device the contacts are saved in your Google account, and not in the phone memory or on the SIM card. Local records are not synchronized automatically.
You can check the availability of contacts in the cloud at any time through a browser on your computer by going to contacts.google.com using your login.
Using the Samsung Smart Switch Mobile application
The company Samsung has developed its own powerful solution for data migration called Smart Switch. This application allows you to transfer not only contacts, but also messages, photos, system settings and even the location of icons on the desktop. To transfer data between two Android devices, Wi-Fi Direct technology is used, which provides high connection speed without the need for an Internet connection.
You need to install the application Smart Switch on both smartphones. On new models Galaxy it is often preinstalled in the folder Samsung. On an old device, you can download it from the store Google Play. After launching the app on both devices, select the device role: on the old phone, click “Send data”, and on the new one Samsung - “Receive data”.
Next, select the connection method. For wireless transmission, press the button Wireless communication on both screens. The phones will start searching for each other. Once the connection is established, a list of data types to transfer will appear on the receiving device. Check the "Contacts" box and start the process. The transfer speed depends on the volume of the phone book, but usually takes no more than a few minutes.
- 📱 High transfer speed thanks to a direct Wi-Fi connection.
- 🔄 Possibility of transferring not only numbers, but also the history of calls and messages.
- 🛡 Security: data is transferred directly between devices without going to third-party servers.
It is worth noting that the application interface may differ slightly depending on the shell version One UI. If the wireless connection is unstable, Smart Switch will suggest using a USB-C to USB-C cable or OTG adapter to create a physical bridge between the devices. This is especially true when transferring huge amounts of data, where channel stability is important.
Transfer via SIM card: classic method
Despite the development of cloud technologies, the method of copying contacts to a SIM card remains in demand, especially when switching from old push-button phones or devices with damaged screens. This method does not require the Internet and complex settings, but has significant limitations on the volume and quality of stored information.
First, insert the SIM card into the old phone. Open the Contacts application, go to the control menu (usually three dots or the More button) and select Import/Export contacts. In the menu that appears, select the "Export to SIM card" option. The system will warn you that only names and numbers will be saved, and additional fields will be lost.
After the export is completed, move the SIM card to a new one Samsung Galaxy. Go to the contacts app on your new device, open the control menu again and select Import/Export contacts. This time specify the source as "SIM Card" and the destination as "Phone" or "Google Account". The import process will start automatically.
| Characteristics | SIM card | Google Account | Smart Switch |
|---|---|---|---|
| Saving photos | No | Yes | Yes |
| Add. fields (address, email) | No | Yes | Yes |
| Record limit | ~250 pcs. | No | No |
| Network dependence | No | Required | No (Wi-Fi Direct) |
⚠️ Attention: Modern SIM cards often have a limitation in 250 contacts. If your phone book is larger, some entries may not be copied or may overwrite existing ones.
Why are names cut off on the SIM card?
The data storage standard on SIM cards is outdated and only supports short text strings. Therefore, when exporting, long names are often trimmed to the first 10-15 characters.
Manual transfer via VCF file
If automatic methods for some reason do not work, you can always use manual export to a file format VCF (vCard). This universal format is supported by all email clients and instant messengers, making it a great tool for backups and manual transfers.
On your old device, open the contacts app and select the export option. Specify the device's internal memory as the save location. The system will create a file named 00001.vcf or contacts.vcf, in which all the data in your phone book will be encrypted in text form.
Next you need to transfer this file to a new one Samsung Galaxy. This can be done in many ways: send via Bluetooth, transfer via instant messenger (Telegram, WhatsApp), upload to cloud storage, or simply transfer via cable when connected to a PC. Having received the file on your new device, just click on it - the system will offer to open it through the contacts application and import all entries.
☑️ Checking the integrity of the VCF file
This method is good because you get a physical backup file that can be stored on a flash drive or computer. If synchronization fails in the future, you can always restore data from this archive. However, when importing a large file (several thousand contacts), the application may freeze for a while, which is normal system behavior.
Solving problems with duplicate contacts
A common problem when changing phones, especially if you used several transfer methods at the same time, is the appearance of duplicate entries. The same contact can be displayed twice or three times: once from the SIM card, the second from the Google account and the third from the local memory. Merging duplicates is an important procedure for putting things in order in the phone book.
Shell One UI on smartphones Samsung has a built-in tool to solve this problem. Go to the Contacts application, click on the menu (three horizontal bars or dots) and select Contact management. In this section you will find the option “Merge duplicate contacts.”
The system will offer two options: automatic merging of all found duplicates or manual selection of pairs for merging. The automatic mode works quite smartly by matching phone numbers and names. After confirming the operation, all unnecessary entries will be deleted, and information from different sources will be combined into one card.
If the built-in tools do not cope, you can use the web version of Google Contacts. On your computer, log into your account and select “Merge and Correction” from the menu on the left. The service will show a list of potential duplicates and allow you to combine them in one click. This is especially convenient if you work with a large database.
Transferring contacts from a locked or broken screen
A particular difficulty is when the old phone turns on, but the screen is broken or the sensor does not work, which makes it impossible to control the interface to start synchronization. In this case, standard methods through the settings menu become unavailable, and the use of external tools is required.
If USB debugging is enabled on your phone, you can connect it to your computer and use command line utilities adb to extract the contact database. However, this method requires technical training. A simpler option is to use a USB hub with OTG support.
Connect a computer mouse and a data cable (or an adapter for a second phone) to the hub. Using the mouse, you can control the interface of the broken phone, unlock it and start the export or synchronization procedure. This is a “lifeline” for many users who are faced with a broken screen before selling or disposing of the device.
⚠️ Attention: Interfaces and menu names may vary slightly depending on the Android version and device model. If you do not find the item you need, use the search in the settings using keywords.
Using a USB mouse via an OTG adapter is the most effective way to control a smartphone with a broken sensor to save data.
