Buying a new Samsung smartphone is always an exciting moment, but it inevitably involves the need to migrate data. Users are often frightened by the prospect of losing contacts, photos or application settings, but the Android ecosystem, and in particular Samsung's One UI shell, provides powerful tools for a seamless transition. Account transfer is the first and most important step, as it is the one that synchronizes your digital life.
The process does not require deep technical knowledge, but it is important to understand the difference between a simple login and a full data migration. Unlike old methods of manual copying, modern protocols allow you to clone folder structures, passwords and even the location of icons on the desktop. Samsung Smart Switch and the built-in mechanisms of Google Play Services take on all the hard work, ensuring the integrity of the information.
In this article we will analyze in detail all the stages: from preparing the old device to the final setup of biometrics on the new device. You'll learn how to avoid common login mistakes and why two-factor authentication can become a barrier if you don't prepare in advance. We'll look at both wired and wireless transmission methods so you can choose the best option for your situation.
⚠️ Attention: If you have the Samsung Smart Switch application installed on your old device, make sure that it is updated to the latest version available in the Google Play store, as older versions may not work correctly with new models of the Galaxy S24 or Z Fold series.
Preparing devices for data migration
Before starting any manipulations, you must carry out basic preparation of both smartphones. This is not just a formality, but a critical stage on which the speed and success of the entire process depends. Make sure that both devices are charged at least 50-60%, since active data transfer via Wi-Fi Direct or cable significantly consumes battery power.
On an old Android smartphone, check that there is free space and that there are no system errors. Users often forget that backup Google cloud access may be interrupted due to insufficient account storage space. Free up space or buy additional storage on Google One if the indicator is full.
It's also worth checking your operating system version. Although transmission protocols are usually backwards compatible, keeping both devices up to date with security patches minimizes the risk of connection failure. On a new Samsung, when you turn it on for the first time, the system itself will offer to update, but it is better to do this on the old device in advance.
☑️ Ready for transfer
Using Samsung Smart Switch for complete migration
The most effective way to transfer an account from Android to Android Samsung is to use a proprietary application Samsung Smart Switch. This tool is designed specifically to make the transition of users from other platforms to Galaxy as comfortable as possible. The application is available for installation from the Google Play Store on any device running Android version 4.3 and higher.
The process begins with installing the application on both smartphones. After launch, you will be asked to select a device role: “Sender” on the old phone and “Recipient” on the new Samsung. The app will automatically find devices if they are nearby and connected to the same Wi-Fi network, or will suggest using a USB-C cable for a more stable and faster connection.
The cable method is preferable if you plan to transfer a large amount of multimedia (4K video, RAW photos). The transmission speed over cable is much higher, and the risk of connection loss due to interference on the air is completely eliminated. The wireless method is convenient because it does not require searching for adapters, but can be slower when the data volume is over 10-15 GB.
In the content selection menu on the sending device, you can configure in detail what exactly will be transferred. You can exclude heavy folders or system files that are not needed in the new location. Smart Switch can even transfer alarm settings, calendar and home screens, recreating a familiar environment.
⚠️ Attention: When transferring data via Smart Switch, some banking applications may require re-authorization or set up biometrics again for security reasons, even if the applications themselves are copied.
Manually setting up a Google account on Samsung
If you decide not to use Smart Switch or are transferring data selectively, manually setting up a Google account is key. This main identifier in the Android system, without which full use of the smartphone is impossible. Logging into your account is required for the Play Store, Gmail, YouTube and contact synchronization.
To add an account, go to the settings of the new device. The path usually looks like this: Settings → Accounts and archiving → Account management → Add account. Select the Google logo from the list that appears. The system will ask you to enter your email address and password.
Particular attention should be paid to the security check. If you sign in from a new device, Google may view this as suspicious activity. A confirmation request may appear on the screen via a notification on the old phone or a code request from SMS. Two-step operation This is a reliable shield, but it requires access to the old number or device.
After successful login, the system will offer to restore the data from the backup. Even without Smart Switch, Google will offer a list of available backups associated with this account. Select the most recent date to get back the list of installed applications, Wi-Fi passwords and system settings.
What to do if you forgot your account password?
If you don't remember your password, use the recovery procedure on accounts.google.com. You will need access to the backup email or phone number you provided during registration. Without this, it is almost impossible to restore access to your Google account.
Synchronizing contacts, calendar and multimedia
After logging in, the background synchronization process begins. This is not an instant action, but a gradual pull-up of data from servers. Contacts and calendar events are loaded first, as they have the least weight. Make sure that the “Contacts”, “Calendar” and “Tasks” items are checked in your Google account settings.
The situation is different with photos and videos. If you have the feature Google Photos with "Original" or "Save Space" quality enabled, then your media files are already in the cloud. On the new Samsung, just open the Google Photos application, and the entire gallery will be available instantly, taking up minimal space on the internal storage.
However, if you prefer to store your files locally, Smart Switch will transfer them to the appropriate folders. It's important to note that the folder structure may be slightly different on the new model due to changes to the One UI file system. Some Android system folders may be renamed, but user content (DCIM, Download, Documents) will retain their names.
| Data type | Transfer method | Speed | Nuances |
|---|---|---|---|
| Contact | Google auto-sync | Instantly | Requires stable Internet |
| Photo/Video | Smart Switch / Cable | High | Takes up a lot of disk space |
| Applications | Google Play Market | Depends on quantity | Banking apps require a separate login |
| Wi-Fi passwords | Backup | Instantly | Works only when restoring from a backup |
Local storage of photos takes up space on the new device, while cloud synchronization saves memory, but requires Internet to view old pictures.
Transferring messages and call history
One of the most delicate tasks is transferring the history of SMS and MMS messages, as well as the call log. Standard Google synchronization tools do not always save the text of SMS messages in full, relying on the capabilities of the operator or third-party applications. Here again Samsung Smart Switchcomes to the rescue, which can pull this data directly from the database of the old phone.
When selecting the type of data to transfer in the Smart Switch application, be sure to check the “Messages” and “Call Log” checkboxes. The process may take some time if the correspondence history is very large (thousands of messages). After completion, you will find that the dialogs in the standard Messages application on Samsung look exactly the same as on the old device.
It is worth noting the peculiarity of working with instant messengers like WhatsApp, Telegram or Viber. They are not carried through the standard SMS mechanism. For WhatsApp, for example, you need to create a backup copy of the chats inside the application on the old phone (to Google Drive), and then, when installing on a new Samsung, select restoring from the copy.
To transfer WhatsApp history without losing data, use the "Transfer chats" function inside the WhatsApp settings on the new phone by scanning the QR code from the screen of the old device. This works faster and more reliably than restoring from the cloud.
Solution and data security
Unforeseen situations may arise during the migration process. One of the common problems is synchronization error due to full Google account storage. If the space runs out, synchronization of contacts and photos will stop. In this case, you need to either remove unnecessary things from the cloud or temporarily disable synchronization of heavy files.
Another important aspect is security. After transferring your account, it is strongly recommended that you check the list of active devices in Google's security settings. Remove old, sold or lost gadgets from there so that they do not have access to your data. Also check if your new phone has saved passwords for unnecessary services.
If you use corporate email or a Google Workspace profile, you may need additional permissions from your domain administrator. Some organization security policies may block the installation of unverified applications or require the installation of a special device profile.
⚠️ Attention: Settings interfaces and menu item names may vary slightly depending on the version of Android and the One UI shell. If you don't find the item, use the settings search (magnifying glass at the top of the screen).
Completing setup and optimizing work
After all the data has been transferred, do not rush to delete information from the old device. Watch the new Samsung in action for a couple of days. Make sure notifications arrive on time, alarms ring, and apps work properly. Sometimes background battery optimization on a new device can “put to sleep” migrated applications, requiring you to manually configure exceptions.
Be sure to set up biometric protection: fingerprint, facial recognition or iris scanning (if supported by the model). This is not only convenient, but also necessary for the operation of Samsung Pay and the protected folder. Biometric data are stored in the secure module of the phone and are not transferred anywhere, so they need to be registered again.
The final touch will be updating all applications through the Galaxy Store and Google Play. Developers often release updates specifically for new models, optimizing the interface for the screen size and resolution of your new smartphone.
Do you need to do a factory reset after the transfer?
Usually this is not necessary, since Smart Switch creates a clean file structure. However, if you notice strange system behavior or application conflicts, a full Factory Reset on the new device after transferring data may solve the problem.
What to do if Smart Switch does not see the old phone?
Try these steps: 1. Make sure both phones are connected to the same Wi-Fi network. 2. Check the permissions for the Smart Switch app on both devices (file access, location, Bluetooth). 3. Restart both smartphones. 4. If the wireless connection is unstable, use a USB-C to USB-C cable or adapter.
Will passwords from Wi-Fi networks be transferred?
Yes, when using Smart Switch or restoring from a full Google backup, passwords from saved Wi-Fi networks will be transferred. The new phone will automatically connect to known networks without having to enter a password again.
How to transfer data if the old phone is broken and won’t turn on?
If the screen does not work, but the phone turns on, try connecting a USB mouse via an OTG cable for control. If the phone is completely dead, you can only recover data from the latest Google cloud copy, if one was made earlier. Local data cannot be saved without turning on the device.
Will data transfer take up space in the Google cloud?
The process of transferring via cable or Wi-Fi Direct does not use the Google cloud, so the quota is not consumed. However, if you back up before transferring or sync photos in original quality, this will consume space in your Google Account.
