Upgrading to a new Samsung smartphone is always a nerve-wracking experience, often overshadowed by the fear of losing important information. Users worry that contacts made over the years will disappear, and photos from trips will remain on the old device. Fortunately, modern technology allows synchronize data between devices without using cables and computers.
The main tool for this task is a wireless connection. Wi-Fi Direct, which is built into the operating system AndroidThis protocol allows two devices to connect directly, creating a high-speed local network, significantly speeding up the migration process. You don't need internet access or a router, as the phones communicate directly with each other.
In this article, we will examine in detail all the current transfer methods, paying special attention to the proprietary application Smart SwitchYou'll learn how to properly prepare both smartphones, the nuances of transferring media, and how to avoid common mistakes. Wi-Fi transfer speeds can reach 40 MB/s, which is several times faster than classic Bluetooth.
Preparing devices before data migration
Before starting the copy process, make sure both devices are ready to use. Charge both smartphones to at least 60%, as active communication modules and screens drain power quickly. If the process is interrupted due to low battery, file corruption or a system crash may occur.
Check if it is enabled Wi-Fi in the settings of both phones. On your new Samsung, make sure there's enough free disk space to accommodate all your apps, photos, and videos. It's also recommended to clear temporary files and cache on your old device to avoid transferring digital junk.
⚠️ Important: Make sure both phones' screens are unlocked when establishing a connection. Locked screens may interrupt the network search process.
It's important to disable power saving mode on both devices. This mode can limit background activity of apps, including Smart Switch, which will result in an unstable connection. Simply go to the battery settings and select "Optimal" or "Performance" mode.
☑️ Preparing for the transfer
Using the Samsung Smart Switch Mobile app
The most reliable and functional transfer method is to use specialized software from the manufacturer. Application Smart Switch It comes pre-installed on most new Samsung models, but can be downloaded for free from Google Play to any Android smartphone. It supports the transfer of contacts, messages, call logs, photos, music, and even home screen layouts.
To get started, launch the app on both devices. On your old phone, select "Send Data," and on your new Samsung, select "Receive Data." The system will prompt you to select a connection method: select "Wireless" or "Wi-Fi." The app will automatically create a secure communication channel between the devices.
Once the devices find each other, a confirmation code will appear on the screen. Verify the numbers and tap "Confirm" on both screens. Next, you'll be asked to select the types of data to transfer. You can select all at once or use selective synchronization, leaving unnecessary files in their old location.
What to do if the devices cannot see each other?
Make sure both phones are close together (within 1 meter). Check that airplane mode isn't enabled on one of the devices. Also, try resetting the Wi-Fi module in settings or temporarily disabling the VPN, which may be blocking the local connection.
The copying process can take anywhere from 15 minutes to several hours, depending on the size of the data. Don't minimize the app or lock your phone screens during the transfer. The progress bar will show the estimated time.
Setting up a Google Account for Cloud Sync
An alternative to a direct connection is to use cloud services. GoogleThis method is ideal if you can't keep both phones on at the same time or if you want to have a cloud backup. When you sign in to your account on your new Samsung, the system will automatically offer to restore your data from the last saved backup.
To ensure it works correctly, you need to check the sync settings on your old device. Open Settings → Accounts and Archiving → Manage AccountsSelect your Google account and make sure the checkboxes next to contacts, calendar, notes, and other important sections are checked.
Particular attention should be paid to photographs. Service Google Photos Allows you to store media files in the cloud. Make sure "Auto Backup and Sync" is enabled on your old phone. After you do this, all your photos will appear in your new phone's gallery immediately after installing the app and signing in.
| Data type | Synchronization method | Free plan limits |
|---|---|---|
| Contact | Google Contacts | 15 GB (shared with mail) |
| Photo/Video | Google Photos | 15 GB (compressed) |
| Applications | Google Play Market | No restrictions |
| Documents | Google Drive | 15 GB |
⚠️ Note: The Settings menu interface may vary slightly depending on your Android OS and One UI version. If you can't find the item you need, use the Settings search.
Transfer media via Wi-Fi Direct and local network
If you need to transfer a huge amount of large video files or archives, and using Smart Switch is not possible for some reason, you can use third-party file managers. Apps like Send Anywhere or built-in Samsung Quick Share (formerly known as Nearby Share) work on the principle of Wi-Fi Direct.
Quick Share is a native feature of the Samsung and Android ecosystems. It allows you to instantly transfer high-quality, uncompressed files. Simply select files from your gallery, tap the "Share" button, and choose a device from the list of nearby devices. Transfer speed is limited only by Wi-Fi capabilities.
This method is good for selective transfers, for example, if you forgot to transfer a couple of music folders after the main migration. However, it's less convenient for a full system backup, as it doesn't transfer app settings and passwords.
Solved issues with wireless transfer
Despite the technology's refinement, the process can sometimes be interrupted or error-prone. One common issue is freezing at the 99% stage. This is often due to a full clipboard or insufficient RAM on the receiving device. In this case, it's best to close all background apps on your new Samsung.
Another common issue is low transfer speed. Make sure you're not connected to a public Wi-Fi network with limited speeds. When using Smart Switch in "Wireless Connection" mode, the internet isn't required; phones create their own network. If you're using cloud-based methods, make sure your router's signal is stable.
It's also worth considering Android version compatibility. Upgrading from very old versions (such as Android 6 or 7) to the latest One UI may require additional time to convert contact and message databases.
Final check and configuration of the new smartphone
After the transfer is complete, don't rush to delete data from your old phone. Conduct a thorough inspection of your new device. Check that all contacts are present, open your gallery, and ensure that albums are organized correctly. Pay particular attention to messaging apps.
To transfer your chat history to WhatsApp or Telegram A separate procedure within the apps themselves is often required, even after a general data transfer. When launching WhatsApp for the first time on a new phone, be sure to select restore from a Google Drive backup.
Make sure all banking apps and two-factor authentication are working correctly. Some banks require device relinking or SMS confirmation when changing hardware. This is a standard security procedure.
What should I do if some SMS messages are missing after transfer?
Messages often fail to transfer if they are stored on the SIM card on the old phone, not in the device's memory. Check the messaging settings on your old device and copy the SMS messages from the SIM card to the phone's memory before launching Smart Switch. Also, some messaging apps may block the import of old databases for security reasons.
Is it possible to interrupt the transfer and continue later?
The pause and resume feature in the Smart Switch app is unstable. If the process is interrupted, it is recommended to restart it. The app will automatically detect and skip files that have already been transferred, but to be on the safe side, it's best to complete the process in one session without long breaks.
Will Wi-Fi network passwords be transferred?
Yes, if you use a Google account for syncing or a full backup via Smart Switch, your saved Wi-Fi network passwords will also be transferred. Your new phone will automatically connect to known networks once they're in range.
