Changing a smartphone often causes stress not because of the cost of the new device, but because of the fear of losing important information. The process of transferring data between devices Samsung Galaxy has become as automated as possible, but many users still rely on manual methods, spending hours saving photos and numbers.
In this article we will analyze in detail all available migration methods, from proprietary utility Smart Switch to cloud solutions. You will learn how to transfer not only media files, but also system settings, home screen layout and even passwords from Wi-Fi networks without losing quality.
Preparing devices before migration
Successful transfer of information depends 90% on the correct preparation of both gadgets. Before running any apps, make sure that the battery level on both your old and new phone is at least 50%. A sudden power outage while data is being written can result in file corruption or operating system failure Android.
It is also critical to free up space on the target device. If you're upgrading from a larger memory model to a smaller one, check to see if all your data will fit. Remove unnecessary cache files and duplicate photos to avoid the "Not enough space" error at the most crucial moment.
⚠️ Warning: If you are using an encrypted SD card, be sure to disable encryption in the security settings before removing, otherwise the new phone will not be able to read the files.
It is also recommended to update the software on both devices to the latest version available. Developers Samsung are constantly improving data transfer protocols, and older versions of firmware may not interact correctly with new information compression algorithms.
Before starting the transfer, delete old, unused applications from the old phone - this will speed up the process and will not clog the memory of the new device with garbage.
Using Samsung Smart Switch: wired method
The most reliable and fastest way to transfer data is to use a USB cable. The proprietary utility Smart Switch is preinstalled on all modern smartphones of the Korean brand. To connect, you will need a USB-C to USB-C cable or an OTG adapter if the device connectors are different.
After physically connecting the phones, the system will automatically prompt you to launch the application. You will need to select the role of each device: "Sender" for the old phone and "Receiver" for the new one. The app interface is intuitive and guides the user step by step.
☑️ Preparing for a wired transfer
A wired connection guarantees a stable transmission speed that does not depend on the quality of the Wi-Fi signal. This is especially true when transferring large volumes of video in resolution 4K or heavy archives with documents.
| Data type | Transfer speed (approx.) | Reliability | Requirements |
|---|---|---|---|
| Contacts and SMS | Instantly | High | Any cable |
| Photos (up to 10 GB) | 5-10 minutes | High | USB 3.0 cable |
| Applications | Depends on size | Medium | Internet for resuming |
| System settings | Instant | High | Same version of Android |
During the copying process, device screens may turn off to save energy, but the process itself will continue in the background. Do not disconnect the cable until a message about the completion of the operation appears.
Wireless transmission via Smart Switch
If you do not have a suitable cable at hand, the technology Wi-Fi Direct allows you to create a direct connection between phones without using a router. This method is convenient when the device connectors are incompatible or the cable is damaged.
To start the process, open the application Settings → Accounts and Backup → Smart Switch. Select the Wireless Transfer option and follow the onscreen instructions. The devices will find each other within range and establish a secure connection.
Wireless transmission speed may vary depending on interference on the air and the number of connected devices nearby. For large archives, this method may take significantly longer than the wired counterpart.
Why may wireless transmission be interrupted?
The Wi-Fi Direct signal is sensitive to physical obstacles and other active wireless devices. Try to place the phones next to each other and move away from microwave ovens or powerful routers.
⚠️ Attention: When transferring wirelessly, make sure that the power saving mode is turned off on both phones, as it may limit the operation of the Wi-Fi module and interrupt the connection.
This method is ideal for regular backups or transferring small amounts of data when speed is not a critical factor.
Synchronization via Google Account
Ecosystem Google offers a deep level of integration that allows you to restore most of the data by simply entering your login and password on a new device. This method does not require the old phone to be physically nearby.
Basic data such as contacts, calendar events and notes are synced automatically. Just go to Settings → Accounts on your old phone and make sure that the switches opposite the necessary services are active.
To back up settings and the list of installed applications, use the “Google Drive Backup” function. It saves the desktop layout, Wi-Fi passwords and system settings to the cloud.
- 📞 Contacts are synchronized instantly and accessible through the web interface.
- 📸 Photos and videos require separate settings in the application Google Photos.
- 📱 The list of applications is restored, but the APK files themselves must be downloaded again from the store.
Recovery from the cloud depends on the speed of your Internet connection. When you turn on the new one for the first time Samsung Galaxy the setup wizard will offer to restore data from a Google backup.
Google Account is the best way to transfer contacts and settings, but for heavy media files it is better to use local methods or cloud storage with a large limit.
Transferring media files: Photos, Videos and Documents
The largest data block is the media library. If you do not want to wait for a long time for synchronization via the Internet, you can use a file manager or connect to a PC. The built-in application My files on Samsung allows you to easily manage internal memory.
When using a PC, create a folder on your hard drive and copy the contents of the folders there DCIM, Pictures i Download. Then connect your new phone and move the files to the appropriate directories. This ensures that the folder structure and metadata are preserved.
An alternative is to use third-party cloud services such as Dropbox or Yandex.Disk. They often provide automatic uploading of photos from the camera, which simplifies the migration process.
⚠️ Attention: When copying via a computer, make sure that the file transfer mode (MTP) is selected on the phone, and not just charging, otherwise the PC will not see the internal memory of the device.
Do not forget about folder WhatsApp or Telegramif you use these messengers. The history of correspondence and received files are stored in separate directories that need to be transferred manually or through the built-in backup functions of instant messengers.
Migration of data from iOS to Samsung
The transition from iPhone to Samsung has become much easier thanks to iOS support in application Smart Switch. You will need a special Lightning to USB-C cable or a wireless connection setup.
The app can transfer contacts, messages, photos, videos and even some settings. However, iOS apps will not be transferred directly as they are not compatible with Android; you will have to find their analogues in Google Play.
To transfer data via cable, connect your iPhone to the new Samsung. On the iPhone screen you will need to confirm your trust in the computer and enter the unlock password. Next, follow the instructions of the transfer wizard.
Function path: Settings → Accounts and Backup → Smart Switch → Accept Data → iPhone/iPadIt is important to note that some data, such as call history or iMessages, may not be transferred completely due to limitations of the Apple operating system.
What what to do with in-app purchases?
In-app purchases (donations, levels in games) are not transferred between different operating systems. You will have to purchase them again in the Android version if the developer does not support a cross-platform account.
Common problems and solutions
Sometimes the transfer process may freeze or fail with an error. Most often this is due to insufficient memory on the target device or an unstable connection. Try rebooting both phones and starting the process again.
If some applications do not install after transfer, check their compatibility with your version of Android. Outdated apps may not be supported on new devices and require updating or replacement.
In case of problems with contacts, check where exactly they are saved. If they are stored on the SIM card, use the import/export function in the contacts application to transfer them to internal memory or Google account.
- 🔄 Connection error: Disable VPN and proxy servers on both devices.
- 💾 Out of space: Delete temporary files or transfer some data to an SD card before beginning.
- 🔋 Quick discharge: Connect both phones to chargers during a long transfer.
Remember that interfaces and menu names may vary slightly depending on the shell version One UI. Always check the manufacturer's current help materials if the standard path does not work.
Can you transfer data if your old phone is broken?
If the screen does not work, but the phone turns on, try connecting a mouse via an OTG adapter for control. If the board is faulty, the data can only be saved through a service center or pre-configured cloud synchronization.
Are application passwords transferred?
Passwords saved in Google Password Manager or Samsung Pass are synced via the cloud. However, passwords stored within specific applications without being linked to an account may be lost.
How long does it take to transfer 100 GB of data?
When using a USB 3.0 cable, the process will take about 20-30 minutes. Over a wireless channel, this can take 1.5–2 hours, depending on the connection speed and the number of small files.
Do you need to reset your new phone to factory settings before transferring?
It is advisable, but not necessary. The Smart Switch Setup Wizard works best on a clean device during initial setup. If the phone is already in use, some data may be duplicated.
