Change using a smartphone always evokes mixed feelings: on the one hand, joyful anticipation of a new experience and modern functions, on the other hand, the fear of losing important contacts, photos or settings of the familiar interface. Switching to an ecosystem Samsung is often a logical step for users who value system flexibility, but want more advanced hardware functionality and optimization. Modern data migration tools have made this process as automated as possible, however, there are nuances that not all users are aware of.
Unlike cross-platform migration, migration between devices based on Android usually goes smoothly, but the transition to Samsung provides access to the corporation’s unique services. You don't need to be a technician to successfully complete all the steps, but it is important to understand the sequence of steps and properly prepare both devices. In this article, we will analyze in detail how to use standard system tools and specialized software so that your new gadget becomes a complete copy of the old one or even better.
The main difficulty often lies not in the copying process itself, but in the preliminary preparation of accounts and passwords. Many people forget that some banking applications and instant messengers require re-authorization or have restrictions on the frequency of changing devices. The correct approach to the issue backup will allow you to avoid a situation where you discover data loss after activating the new device. Let's look at all the stages in detail to eliminate any risks.
Preparing devices before migration
Before running any migration apps, you need to make sure that both devices are in good condition and ready for intensive work. Charge your old and new smartphone to at least 60-70%, since the process of active data transfer, especially via Wi-Fi Direct, can significantly consume battery power. It is also recommended to free up space on the new device, if it is not new, by deleting unnecessary files to avoid write errors.
A critical step is to check for operating system updates on both devices. Developers are constantly improving data transfer protocols, and an old version of Android on one of the devices may cause a crash or incorrect display of contacts. Go to Settings → System → Software Update and make sure that the latest available security patches are installed.
⚠️ Attention: If your old device has custom firmware installed or root access has been obtained, standard transfer methods may not work correctly. In such cases, it is recommended to first perform a full backup on your computer, and install only proven applications on your new Samsung.
Don't forget to check the stability of your Internet connection if you plan to use cloud services for some of your data. Although the bulk of information (photos, videos, applications) is transmitted over a local channel, synchronization of passwords, notes and calendar depends on the connection speed with Google or Samsung Cloud servers. Make sure that Wi-Fi and Bluetooth are turned on on both devices.
Using the Samsung Smart Switch application
The main tool for migration is the proprietary application Smart Switch, which is preinstalled on all modern Samsung smartphones. If your old Android device does not have it, you need to download the APK file from the official website or find the application on the Google Play Store. This software is designed specifically to make the transition between different brands of Android devices seamless for the user.
The process begins by launching the application on both smartphones. On your new Samsung, select the “Receive Data” option, and on your old device, select “Send Data.” The system will prompt you to choose a connection method: wireless or using a USB-C cable. The wireless method is convenient because it does not require additional accessories, but it can be slower when transferring a large volume of video files.
When choosing a wireless connection, the devices will find each other via Wi-Fi Direct. You will need to confirm the connection request that appears on the screen of your old phone. Once the connection is established, Smart Switch will analyze the contents of the old device and offer to select categories of data to transfer. You can copy everything at once or selectively, for example, only contacts and messages, leaving media files for manual download later.
☑️ Checklist before launching Smart Switch
If you use a cable, the process will go much faster and more stable. To connect, you may need a USB-C to USB-C adapter or an OTG adapter if the connectors on the devices are different (for example, the old micro-USB and the new USB-C). A cable connection also allows you to transfer data that, for security or format reasons, is not transmitted over the air.
Google account setup and synchronization
The foundation of the Android ecosystem is your Google account. When you turn on your new Samsung for the first time, the system will prompt you to log into an existing account or create a new one. Logging into the same account that was used on the old device will automatically start the background synchronization process. This means that your contacts, calendar events, Google Keep notes, and passwords saved in Chrome will start appearing on your device without your intervention.
It's important to understand the difference between Smart Switch transfer and Google sync. The Samsung app copies physical content (gallery photos, app APKs, desktop layout), while Google restores the digital profile user. Without setting up your account correctly, you risk losing access to purchased applications, subscriptions, and location history.
After logging into your account, go to the synchronization settings to make sure that all the necessary items are active. The path to the settings usually looks like Settings → Accounts and Backup → Account Management → Google. Here you can force synchronization for specific services by clicking on the update button.
What to do if two-factor authentication is enabled?
If you have 2FA enabled and your old phone has already been reset or is not available, you will need the backup codes that you should have saved when setting up security. Without them or access to the phone number, it will be extremely difficult to restore your account. Always keep backup codes in a safe place, separate from your phone.
Application passwords deserve special attention. Some apps, especially banking or corporate ones, may require you to reset your password when you change devices for security reasons. Make sure you have access to a phone number to receive SMS verification codes, as the SIM card will need to be moved to the new device.
Transferring multimedia and system settings
The most extensive step is transferring photos and videos. Smart Switch by default copies the contents of the DCIM, Pictures and Downloads folders. However, if you used third-party galleries or saved files in non-standard directories, you will have to transfer them manually or through a file manager. Once the copying is complete, check that all albums are present in the application Gallery.
System settings such as alarms, Wi-Fi hotspots, wallpapers, and widget locations are also subject to transfer. On Samsung devices with One UI, this process runs most smoothly, recreating a familiar environment. However, it is worth considering that some settings specific to the manufacturer of the old phone (for example, Xiaomi or Huawei branded gestures) will not be transferred or will be replaced by analogues from Samsung.
| Data type | Transfer method | Probability of success | Note |
|---|---|---|---|
| Contact | Google Sync / Smart Switch | 100% | It is better to store in Google, not in the phone's memory |
| Photo/Video | Smart Switch (Cable) | 98% | EXIF metadata may be lost with the wireless method |
| Messages (SMS/MMS) | Smart Switch | 95% | MMS attachments may not open in older formats |
| Applications | Google Play / Smart Switch | 90% | Some paid applications may require re-purchase |
| Wi-Fi passwords | Smart Switch | 85% | Depends on the version of Android on the old one device |
A special case is high-resolution multimedia files. If you shot video in 4K or 8K, make sure your new phone's file system can support those sizes. Modern Samsung uses a file system compatible with large files, but when transferring via FAT32 on older memory cards, restrictions may arise.
Working with instant messengers and social networks
Messengers represent a separate category of complexity, since they store the history of correspondence locally on the device or in their own clouds, ignoring standard Android backup methods. For WhatsApp You need to create a backup copy in Google Drive on your old phone in advance. When you first launch WhatsApp on a new Samsung, the application itself will offer to restore history from the cloud.
⚠️ Attention: The process of transferring WhatsApp chats only works if you use the same phone number and the same Google Drive account. The transition between iOS and Android requires a separate procedure via a cable, but between Android devices everything goes through the cloud.
Telegram, Viber and Signal work on similar principles, but have their own nuances. Telegram stores all history on the server, so you just need to enter your phone number and all chats will appear instantly. Viber requires the creation of a local or cloud backup (Viber Backup), which must be activated in the settings of the old phone before moving. Signal requires creating a backup of the database file, which must be manually transferred to a new device, since Signal does not store data on its servers.
Social networks (Instagram, Facebook, TikTok) do not store local chat history in a form accessible for transfer within the system. You will need to log in again to each application. It is recommended to make sure in advance that you remember passwords or have access to linked mailboxes to restore access.
For banking applications (Sberbank, Tinkoff, etc.), do not count on automatic transfer of sessions. You will have to re-enter your login and password, and also, possibly, confirm your login via SMS or push notification on another trusted device.
Completing the transfer and initial optimization
After the main body of data has been transferred, do not rush to delete information from the old device. During the first few hours, the new smartphone will actively index files, load heavy applications and set up background processes. At this time, the device may noticeably heat up and discharge faster - this is normal system behavior after migration.
Check the basic functions: make a test call, send a message, open several applications. Make sure alarms are set correctly, as this is one of the most critical features that can easily be overlooked. It's also worth checking your biometrics settings: fingerprints and facial scanning will have to be set up again, as this data is stored in the secure module of each individual device and is not transferable.
If you find that some applications are unstable or do not open, try clearing their cache or reinstalling them from the Galaxy Store or Google Play. Sometimes older versions of apps may conflict with the new version of Android on Samsung. Updating all applications to the latest versions is a mandatory step for stable operation.
The full optimization cycle after the move takes up to 24 hours. Don't panic if the battery doesn't hold up as well as usual on the first day—the system needs time to learn and calibrate.
It's also important to set up new Samsung exclusive features like Good Lock to personalize the interface or Samsung Pay for contactless payments. These tools will make using your new smartphone much more comfortable and adapt it to your personal habits.
What to do if contacts are lost after the transfer?
Most often, contacts are not lost, but simply hidden or synchronized with another account. Go to the Contacts application, tap the menu (three bars) and select Manage Contacts → Displayed Contacts. Make sure the “All contacts” checkbox is checked. Also check which account the default contacts are saved in - sometimes they end up in the phone’s memory, not in Google, and when the priority of accounts is changed, they stop being displayed.
Is it possible to interrupt the data transfer process?
It is highly not recommended to interrupt the process, especially when using a cable. An interruption may result in corrupted database files or partial migration of applications, causing system errors. If the process is frozen (more than 1-2 hours without moving the progress bar), try a soft reboot of both devices, but be prepared for the fact that you will have to start the procedure again.
Do you need to format your old phone before selling it?
Yes, definitely. After successfully transferring all data and checking its availability on the new device, perform a Factory Reset on the old phone. Simply deleting files manually is not enough - the data can be recovered. Resetting via the menu Settings → General settings → Reset guarantees the removal of all personal information.
