Buying a new smartphone always causes mixed feelings: the joy of owning advanced technologies and slight panic due to the need to transfer accumulated information. Ecosystem owners Samsung are in a more advantageous position, since the Korean giant has developed a powerful tool for migration. However, many users still transfer contacts manually or lose important photos, not knowing about the capabilities of proprietary software.
The process of switching to a new one Samsung Galaxy has become as automated as possible, but requires proper preparation of both devices. An incorrect sequence of actions can lead to duplicate files or loss of chat history in instant messengers. In this article, we will look at not only the standard path through Smart Switch, but also alternative methods for difficult cases when the old device does not turn on or is running on a different operating system.
Before taking active steps, make sure that both gadgets are charged at least 50-60%. The process of cloning a system, especially if there are hundreds of gigabytes of data, can take anywhere from 30 minutes to several hours. Interruption of transmission at a critical stage sometimes leads to software failures that require a complete reset of the new device.
Preparing devices for synchronization
Successful transfer begins long before you press the “Start” button. The first thing you need to do is update the software on both devices to the latest available version. Developers are constantly improving data transfer protocols, and older versions of firmware may not work correctly with new file formats or applications.
Free up space on the target device if you plan to transfer data not to a clean phone, but to a device that has already been used. Check the availability of free space in the partition Settings → Device maintenance → Memory. If there is not enough space, the system will simply interrupt the process or transfer only part of the information.
Particular attention should be paid to accounts. Make sure you remember the password for your Google account and account Samsung. After transferring data, the security system may require re-authorization to access encrypted files, cloud storage and password backups.
⚠️ Attention: If SD card encryption is enabled on your old phone, transferring data from it may not be possible without first removing the protection. In this case, the files will have to be copied via a computer.
It is also recommended to disable the power saving mode on both devices. Aggressive battery optimization can break the Wi-Fi Direct connection or slow down the processor, which is critical when transferring large amounts of data via cable.
☑️ Preparing for data transfer
Using the Smart Switch application: Wireless method
Proprietary utility Smart Switch is the gold standard for owners of Samsung equipment. It comes pre-installed on most modern models and allows you to transfer contacts, messages, photos, videos, music, documents and even your home screen layout. The wireless method is the most convenient, as it does not require searching for adapters or cables.
First, launch the application on both devices. On the new phone, select the “Receive data” mode, and on the old phone, select “Send data”. The system will automatically prompt you to select the connection type. Wireless transmission uses technology Wi-Fi Directthat creates a direct secure connection between gadgets without affecting your home network.
After the connection, the phones will scan the available content. Here you can flexibly configure what exactly needs to be transferred. You should not blindly agree with all the points if you want to start with a “clean slate” in some aspects, for example, do not transfer old alarm settings or specific system logs.
It is important to note that the wireless transfer speed greatly depends on the number of files and their size. Small files such as contacts and SMS are copied almost instantly, while photo libraries can take tens of minutes to transfer. During the process, keep the devices close to each other and do not lock the screens for a long time so that the connection does not break.
Once the process is complete, the new phone will offer to optimize the transferred applications. This is an important step, since some apps require additional settings of permissions or logging into accounts within the application itself, even if the icon has already appeared on the desktop.
⚠️ Attention: When connected wirelessly, do not open other heavy applications or games on your old phone. This may overload the radio and cause data packets to be lost, causing the transfer to fail.
Transferring data via a USB-C cable
If you have the opportunity to use a cable, this is the most reliable and fastest way to migrate. The data transfer speed over a wire is much higher than over the air, which is critical when transferring tens of gigabytes of video archives or heavy games. The connection usually requires a cable USB-C to USB-C or a special adapter, which is often included with new flagships.
Connect both devices with a cable. A request for permission to access data will appear on the screen. Confirm the action on your old phone by clicking “Allow” or “Trust this computer/device.” In the application Smart Switch the interface will automatically switch to wired connection mode, which is indicated by the corresponding icon.
The cable connection is more stable: it is not affected by interference from other Wi-Fi networks or Bluetooth devices. In addition, during the transfer process, the new phone can even be recharged from the old one (if it has sufficient charge), which reduces the risk of power outage at a critical moment.
| Parameter | Wireless method (Wi-Fi) | Wired method (USB) |
|---|---|---|
| Transmission speed | Average (depends on interference) | High (stable) |
| Convenience | High (no wires needed) | Medium (needs cable/adapter) |
| Reliability | Average (risk of breakage) | High |
| Battery consumption | High on both devices | Low (recharging is possible) |
After physical connection, the algorithm of actions is identical to the wireless method: selecting data, confirming and waiting for completion. The only difference is that you can calmly put down your phones and go about your business without fear that a random movement will break the connection.
Use the original cable that came with your new phone. Cheap third-party cables often only support charging and are not capable of transferring data at high speeds, which will result in a connection error.
Restoring from a Google Drive backup
Ecosystem Google offers a universal transfer method that works not only between Samsung phones, but also when moving from any other Android smartphone. This method is ideal if you don't have your old device with you when you set up a new one, but have a recent backup in the cloud.
A backup to Google Drive usually includes a list of applications, call history, contacts, SMS and device settings. However, it is important to understand that the application files themselves (APK) and their data (cache, logins within games) are not always completely saved. Many developers limit backup to system data.
To use this method, when you first set up a new phone, connect to Wi-Fi and sign in to your Google account. The system will automatically detect an available backup and offer to restore data from it. You can select a specific backup date if there are several of them.
After restoring the bulk of the data, photos and videos can be loaded separately through the app Google Photosif media file synchronization has been enabled. This allows you not to take up space in the system backup and manage your gallery more flexibly.
⚠️ Attention: Free space in Google Drive is limited to 15 GB. If your backup exceeds this limit, old data may not be saved or the synchronization process may stop. Check the available space in the Google Drive app before purchasing a new phone.
Transfer from iPhone to Samsung
Many users are switching from iOS to Android, and Samsung has provided a special scenario for such cases. The application Smart Switch is available in the App Store, which allows you to initiate data transfer directly from the iPhone. To connect you will need a special adapter Lightning on USB-C or using a wireless connection.
With a wired connection, the process goes as smoothly as possible. After connecting and entering your iPhone password on the Samsung screen, you can transfer contacts, calendars, photos and videos. Messages iMessage cannot be transferred due to the closedness of the Apple protocol, but regular SMS migrate without problems.
Paid applications deserve special attention. Purchased apps from the App Store are not transferred to Android, since these are different stores with different licenses. You will have to re-purchase the necessary software from Google Play or look for free analogues.
What to do with WhatsApp when switching from an iPhone?
Transferring WhatsApp chat history from iOS to Android is possible, but only with the initial setup of the phone via a cable. From the Smart Switch menu, select transfer data from iPhone, and the setup wizard will prompt you to transfer WhatsApp chats. After the process is completed, you will need to install WhatsApp on the new phone and log in with the same number.
It is also worth considering the differences in the organization of the file system. On iPhone, files are often hidden within apps, while on Android they are accessible through the file manager. After transfer, check the folder Download or DCIMto make sure that all media files are displayed correctly in the gallery.
Manual transfer and working with cloud services
Sometimes automatic methods do not work, for example, if the old device is badly damaged or It has non-standard firmware. In such cases, manual transfer via a computer or third-party cloud storage comes to the rescue.
Connect the old phone to the PC in file transfer mode (MTP). Copy the folders DCIM (photos and videos), Download, Documents and Music to your computer’s hard drive. Then connect your new Samsung and transfer the data to the appropriate directories. This is the most labor-intensive, but most controlled method.
For contacts and calendar, synchronization through a Google account remains the best solution. Go to Settings → Accounts on your old phone, select Google and make sure the checkboxes next to “Contacts” and “Calendar” are active. After logging into the same account on a new device, the data will appear automatically within a few minutes.
Messengers like Telegram store the entire correspondence history on their servers, so they just need to install the application and log into your account. But for WhatsApp i Viber you need to create a local or cloud backup inside the settings of the messenger itself on your old device before moving.
Manual transfer via a PC is the only guaranteed way to save data from a phone that does not turn on completely, but is recognized by the computer as a drive.
Frequent problems and their solutions
Even if all instructions are followed, users may encounter technical difficulties. One of the most common problems is an "Out of Memory" error on the receiving device. In this case, it is worth removing unnecessary system applications or transferring data in parts, choosing only the most important.
Another common situation is that the process freezes at 99%. This usually means that the system is trying to restore the last major application or file. Don't rush to reboot your phone. Wait 10–15 minutes. If progress has not been made, you can try a forced reboot, but there is a risk of losing some of the data.
If some applications do not work after the transfer, try clearing their cache via Settings → Applications. Sometimes old settings conflict with a new version of Android installed on a fresh smartphone. In extreme cases, removing and reinstalling the problematic software helps.
Can I interrupt the data transfer and continue later?
Unfortunately, the Smart Switch app does not support pause and resume functionality. If the process is interrupted, it will have to be started again. However, the system is smart: it will not duplicate already transferred files, but will check their presence and copy only the missing elements, which will save time when trying again.
Are passwords from Wi-Fi networks transferred?
Yes, when using Smart Switch or restoring from a full Samsung/Google backup, Wi-Fi network settings and their passwords are transferred. You will be able to connect to familiar networks without re-entering security keys immediately after setup.
What to do if contacts were transferred in duplicate?
The Contacts application on Samsung has a built-in management function. Go to the menu (three bars) → Manage contacts → Merge contacts. The system will automatically find duplicates with the same names or numbers and offer to combine them into one card.
How long does it take to transfer 100 GB of data?
The time depends on the connection method. Using a USB 3.0 cable, the process will take approximately 20–40 minutes. With a wireless connection via Wi-Fi Direct, this can take 1.5–2 hours. The speed also depends on the number of small files: a million photos take longer to copy than one movie of the same size.
Do you need to reset your new phone to factory settings before transferring?
If you have already started using your new phone and set it up as a new device, the Smart Switch feature will still work. However, for ideal system cleanliness and to avoid settings conflicts, experts recommend transferring data at the initial setup stage immediately after turning on the device.
