Moving to a new smartphone is often perceived as a stressful event, because it is necessary to transfer a huge amount of personal information. Users often wonder how to scan data from a phone to an Android phone so as not to lose contacts, photos and application settings. Modern technologies make it possible to complete this procedure in a matter of minutes without the use of a computer or complex wires.
The process of data migration has evolved from the use of memory cards to cloud synchronization and direct wireless exchange. Today, there are dozens of methods, each of which has its own advantages depending on the state of the old device and the version of the operating system. Choosing the right tool is critical to maintaining the integrity of your files and the security of your personal information.
In this guide, we will take a detailed look at all the current methods of transferring information between Android-based devices. You will learn about the built-in functions of the system, third-party utilities and specific settings that will ensure a seamless transition to a new gadget.
Built-in data migration tools at first start
Most modern smartphones prompt the user to configure the device immediately after turning it on. At this stage, the system will automatically offer to restore data from a backup or transfer it directly from the old gadget. This is the most reliable method, since it is integrated directly into the operating system shell and does not require the installation of additional software.
To begin the process, you need to place both devices next to each other and make sure that they are connected to a power source. On the new phone, in the setup wizard, select the option Copying applications and data. The system will prompt you to use a cable or wireless connection. When choosing a wireless method on your old device, you will need to log in to the same account Googleas on the new one.
The scanning and transfer process takes time, depending on the amount of information. During transmission, device screens may periodically turn off to save power, but interrupting the connection is not recommended. The system will independently detect compatible applications and transfer them, as well as restore call history and SMS messages.
⚠️ Attention: If your old device has custom firmware installed or does not have Google services, the built-in method may not work correctly. In this case, it is better to use third-party solutions or a cable connection.
☑️ Preparing for data transfer
Using QR codes for quick synchronization
One of the fastest ways to establish a connection between devices is scanning QR code. This method is often used in Quick Connect features or instant messengers to synchronize sessions. The camera of the new phone reads the encrypted pattern on the screen of the old device, after which it automatically sets up a secure communication channel.
To initiate transfer via QR code, open the settings on your new smartphone and find the section Connecting a device. A unique code will appear on the screen. On your old phone, launch the camera or a special data application and point the lens at the code. The devices will exchange encryption keys and establish a direct connection using the protocol Wi-Fi Direct.
This method is especially convenient because it does not require entering passwords or manually searching for devices in the Bluetooth list. The transfer speed when using Wi-Fi Direct can reach tens of megabits per second, which is much faster than classic Bluetooth. However, for correct operation, the cameras of both phones must be in working order, and the screens must have sufficient brightness.
Make sure that there is no protective film on the screen of the old phone with strong glare, this may prevent the camera of the new device from reading the QR code correctly.
Helper applications for cross-platform transfer
If built-in tools can’t cope or you are switching from a device from another manufacturer, specialized applications come to the rescue. The market leaders are utilities like SHAREit, Xender or proprietary solutions from manufacturers, such as Smart Switch from Samsung and MI Mover from Xiaomi. These apps create a local network between phones.
The principle of operation of such applications is that one device becomes an access point, and the other connects to it. After connecting, the user selects categories of data to transfer: contacts, media files, documents or installed applications. Compression algorithms allow you to speed up the process and minimize errors when transferring bad sectors.
An important advantage of third-party applications is the ability to select specific files, rather than completely copying the entire system. This is useful if you need to transfer only a photo archive or a specific folder with documents, without clogging the new phone with unnecessary junk from the old one.
| Application | Connection type | iOS support | Features |
|---|---|---|---|
| Smart Switch | Wi-Fi / USB | Yes | Deep integration with the Samsung ecosystem |
| SHAREit | Wi-Fi Direct | Yes | High speed, works without the Internet |
| Send Anywhere | Internet / P2P | Yes | Transfer by 6-digit code via network |
| MI Mover | Wi-Fi Direct | No | Optimized for Xiaomi and Redmi devices |
NFC technology and contactless transfer
Technology NFC (Near Field Communication) allows you to exchange data when devices are physically in contact or are brought as close as possible. Although NFC has low throughput, it is ideal for quickly transferring contacts, links or connection settings, acting as a “trigger” for faster protocols.
To transfer data via NFC, you must activate the function in the menu Settings → Connected devices → NFC. After turning on, place the back panels of the phones next to each other. A request will appear on the screen to confirm the transfer of the file via Android Beam (or its modern analogues). After confirmation, the transfer will begin.
It is worth noting that in the latest versions of Android, the Android Beam functionality has been eliminated in favor of more universal solutions such as “Quick Share”. However, NFC is still used to instantly pair devices before bulk data transfer over Wi-Fi begins.
⚠️ Warning: Metal cases or cards inserted into the phone case may shield the NFC signal. Remove the case before attempting to connect.
Cloud services as an alternative to direct scanning
Sometimes direct data transfer is not possible due to a broken screen of the old phone or incompatibility of OS versions. In such cases, the optimal solution is to use cloud storage. The service Google Photos automatically uploads media files to the cloud, from where they can be downloaded on the new device.
To synchronize contacts and calendar, just make sure that Google account synchronization is enabled on your old device. The data is stored on the company’s servers and will automatically appear on the new phone immediately after entering your login and password. This eliminates the need to keep both phones on at the same time.
However, the cloud method has limitations related to the amount of free storage. If your photo archive exceeds 15 GB, you will need to purchase additional space or use alternative services, such as Yandex.Disk or Dropbox.
What to do if there is not enough space in the cloud?
If the storage limit is exhausted, you can temporarily buy additional volume for a month, transfer your data and then cancel your subscription. Or use a computer as an intermediate link to unload the archive.
Solving problems during data transfer
Despite the smooth running of the processes, users may encounter errors when scanning or transferring. A common problem is connection loss due to power-saving modes. The system can forcefully turn off the Wi-Fi module to save battery, interrupting file transfer.
Conflicts between application versions are also possible. If your old phone has a very old OS version, the new device may not recognize some file formats or database structures. In such cases, it is recommended to update the firmware on both devices to the latest available version before starting the migration.
If the transfer is stuck at a certain percentage, try clearing the cache of the application responsible for the transfer or rebooting both devices. Sometimes it helps to disable VPN services and antiviruses, which can block local network traffic between gadgets.
The stability of data transfer directly depends on the battery charge level and the absence of background processes consuming network resources.
⚠️ Attention: Menu interfaces and item names may differ depending on the phone model and the manufacturer's shell version. Always check the official documentation of your device.
Frequently asked questions (FAQ)
Is it possible to transfer data if the screen of an old phone is broken?
Yes, this is possible, but you will need to connect a mouse or keyboard via a USB-OTG adapter to control the smartphone. If the image is not displayed, you can try connecting the phone to the PC and copying the files manually through the file manager if USB debugging is enabled.
Is it safe to use third-party applications to transfer banking data?
Most applications only transfer app shortcuts, and not the data itself inside them. Banking apps require you to re-authorize and set up biometrics on a new device for security purposes. The file transfer itself through trusted utilities is encrypted and safe.
How long does it take to transfer 100 GB of data?
When using Wi-Fi Direct or a USB-C to USB-C cable, transferring 100 GB can take from 30 minutes to 1.5 hours depending on the memory writing speed of the new device. Through the cloud, this process can last several hours or even days, depending on the Internet speed.
What to do if contacts are not displayed after the transfer?
Check the display settings in the Contacts application. You may have selected filtering only by SIM card or specific account. Make sure that the Google account synchronization is completed and the contacts are saved there and not in the phone memory.
Is it possible to interrupt the transfer process and continue later?
The built-in Android tools usually do not support resuming when the connection is lost, the process will have to start again. Some third-party applications, such as SHAREit, allow you to resume transfers from where they were interrupted if the files have already been partially written.
