Migration to a new smartphone: How to save and transfer all data to Android

Buying a new gadget is always a joyful event, accompanied by an inevitable headache: how to transfer all contacts, photos, correspondence and settings from the old device? Many users fear that during the migration process some important information will disappear forever or that they will have to spend a day manually setting up each application. Fortunately, the ecosystem has made huge strides in recent years, offering many automated solutions for seamless transition between devices. The process of transferring data (or Android has made huge strides in recent years, offering a variety of automated solutions for seamless transitions between devices.

Data transfer process (or migration) depends not only on the version of the operating system, but also on the manufacturer of your equipment. Devices from Samsung, Xiaomi, Huawei and other brands often have their own utilities that are faster and more reliable than Google's standard tools. However, universal methods, such as backing up to the cloud or using a cable, remain relevant for any model. In this article we will look at all possible methods - from cloud services to direct connection via Wi-Fi Direct.

Before you begin any action, it is critical to ensure that both devices have sufficient battery power. The process of transferring large amounts of information, especially photos and videos, can take from 30 minutes to several hours. If one of your devices shuts down mid-process, you risk corrupted files or incomplete contact transfers. It is recommended to connect both smartphones to power sources or make sure that their charge is at least 60-70%.

Preparing the old device for migration

The success of the entire operation depends 90% on the quality preparation of the data source. Before running any transfer utilities, you need to audit the content on your old phone. Remove unnecessary screenshots, duplicate photos, and frozen app caches so you don't overload your new device's storage with junk. Also check that all critical applications are updated to the latest versions, as older versions may not work correctly with new backup formats.

Particular attention should be paid to authorization in key services. Make sure that you remember the password for your main Google accountas it is through it that contacts, calendars and the list of installed applications are synchronized. If you use instant messengers like WhatsApp or Telegram, check their internal backup settings. For WhatsApp, for example, you need to manually start creating a backup on Google Drive right before replacing the phone in order to save the correspondence history.

⚠️ Attention: If banking or government services applications are installed on your old phone, make sure that you have access to the phone number to which they are linked. After transferring data and inserting a new SIM card, some banks may require re-verification via SMS or biometrics.

Another important nuance is freeing up space. It’s paradoxical, but for some system transfer utilities to work correctly, the old device must have at least 10-15% free memory. This is necessary to create temporary archiving files. If the memory is full, the process may be interrupted with an “Insufficient space” error, even if the new phone has hundreds of gigabytes of free space.

Using a Google account for basic synchronization

The most universal and reliable method that works on any Android smartphone is to use Google cloud services. This method is ideal for transferring contacts, notes, calendars, and a list of installed applications. When you first set up a new phone, the system itself will offer to restore data from the latest backup found in your account. All you have to do is enter your username and password.

For this method to work effectively, you need to check the synchronization settings on your old device in advance. Go to the menu Settings → Accounts → Google and make sure that all the necessary items are checked: Contacts, Calendar, Documents, Photos. After enabling synchronization, click the "Synchronize" button manually to force the sending of data to the server.

Data type	Synchronization method	Limits and features
Contact	Google Contacts	Almost unlimited, synced instantly
Photos and videos	Google Photos	15 GB free (shared with Mail and Drive)
Applications	Play Market	Shortcuts are restored, the data inside may not be saved
Wi-Fi passwords	Google Smartlock	Requires activation on both devices and close location

It is worth noting that Google backup does not always save the contents of applications. For example, progress in games or files inside instant messengers often remain on the device if the developer has not provided cloud saving. In such cases, you have to rely on the built-in functions of specific apps or use specialized utilities from phone manufacturers.

Branded utilities from manufacturers: Samsung, Xiaomi, Huawei

Large vendors understand that standard Google tools are not enough for complete migration, so they develop their own powerful tools. These apps allow you to transfer data directly from your old phone to a new one via Wi-Fi Direct, which is much faster than uploading to the cloud and downloading back. In addition, they often know how to transfer system settings, the arrangement of icons on the desktop, and even alarm clocks.

For owners Samsung the gold standard is the application Smart Switch. It is preinstalled on most brand devices and allows you to transfer data not only from other Android smartphones, but also from iPhone. The process is intuitive: you launch the app on both phones, select the "Sender" and "Recipient" roles, scan the QR code and select the data to transfer. The utility itself optimizes the transmission, choosing the best communication channel.

Users Xiaomi, Redmi and POCO should pay attention to the application Mi Mover. It works on a similar principle, creating a temporary Wi-Fi hotspot for transferring files. A special feature of Mi Mover is the ability to transfer MIUI system settings, which allows the new phone to become an almost complete copy of the old one in terms of interface. Huawei (Phone Clone) and Realme (Clone Phone) have similar solutions.

⚠️ Attention: When using proprietary utilities, make sure that the power saving mode is disabled on both devices. Aggressive battery optimization can break the Wi-Fi connection in the background, which will lead to a data transfer error mid-process.

What to do if the proprietary utility does not see the second phone?

If the application does not find the second device, check if airplane mode or VPN is enabled on one of them. Also try turning off mobile data on both devices, leaving only the Wi-Fi module active to create a direct connection. Sometimes rebooting both smartphones before trying again helps.

The main advantage of such solutions is speed. Direct transfer via Wi-Fi Direct can reach speeds of 20-40 MB/s, which allows you to transfer 100 GB of data in a couple of hours. At the same time, you do not need a computer, cable or stable home Internet. Everything happens locally between two gadgets.

Wired method: Transfer via USB cable

If you prefer reliability to wireless technologies, or the amount of data is hundreds of gigabytes, the wired method will be the most stable option. Modern smartphones support connecting to each other via a USB-C to USB-C cable (or via a USB-C to USB-A adapter). This method is often suggested by the setup wizard when you turn on a new device for the first time.

To implement this method, you will need the appropriate cable. Connect the old phone to the new one, and the screen will ask you to allow data transfer. Select "File Transfer" or "MTP" mode. The Android system will automatically start the copying process. This is the most secure method in terms of data integrity, as it is less susceptible to interference from other Wi-Fi networks or Bluetooth devices.

However, the wired method has its limitations. Not all cables are created equal: some cheap cables only support charging and do not transfer data. Use the original cables supplied or certified high quality accessories. In addition, if you have an old phone with a Micro-USB connector and a new one with USB-C, you will definitely need an adapter, which is not always included with the new device.

Manual copying through a computer and memory cards

In situations where automatic methods fail, or you need to transfer data from a broken screen (if the sensor is partially working), the good old computer comes to the rescue. This method requires more time and manual work, but gives you complete control over exactly which files are transferred. It is ideal for sorting archives of photos and documents.

Connect your old phone to your PC via a USB cable and select file transfer mode. Open Windows Explorer or Finder on your Mac, locate your device, and copy the DCIM (camera photo), Download (downloads), Music and Documents folders to your computer's hard drive. Then connect the new phone and move these folders to the appropriate directories in the internal memory.

For users of smartphones with memory card support microSD the process is even simpler. You can simply move the memory card from your old phone to your new one. However, there is an important nuance here: some applications bind their data to a specific path on the memory card or encrypt it. After rearranging the card, the gallery may not immediately see all the photos - in this case, you will need to launch the "Media Scanner" application or simply restart the device.

Transfer of messengers and specific data

The most problematic category of data when moving is messengers. WhatsApp, Viber and Telegram store correspondence history in different ways. Telegram stores everything in the cloud, so you just need to log in to a new device and the entire history will be downloaded automatically. With WhatsApp the situation is more complicated: the history is stored locally or in a Google Drive/iCloud backup.

To transfer WhatsApp from Android to Android, the easiest way is to use the built-in migration feature when you first set up your phone, or restore data from Google Drive when installing the application. It is important that the new phone uses the same phone number and the same Google account. If you are changing platforms (for example, from iPhone to Android), you will need a special cable and the Transfer to Android utility from Google, since the backup structures are different.

⚠️ Attention: Two-factor authentication in instant messengers can block login on the new device if you do not have access to the old phone to obtain the code or backup codes. Be sure to disable 2FA or save backup codes before handing over your old device for Trade-in or sale.

Don't forget about authenticators (Google Authenticator, Microsoft Authenticator). These applications are not migrated using standard methods for security reasons. Before replacing your phone, be sure to use the "Export accounts" function inside the authenticator application to receive a QR code to transfer keys to a new device, otherwise you will lose access to all services protected by two-factor verification.

Frequently asked questions (FAQ)

What to do if, after transferring, contacts are displayed as numbers without names?

This happens when contacts are saved not in your Google account, but in the phone memory or on the SIM card. Go to the Contacts application, select settings and the "Import/Export" function. Import contacts from the SIM card or phone memory into your Google account, and then perform synchronization.

Is it possible to interrupt the data transfer process if it is frozen?

It is highly not recommended to interrupt the process by forcefully shutting down, especially with a wired connection. This may damage the file system. If the process is frozen for more than an hour, try a soft reboot of both devices, but be prepared that some of the data may not be transferred and the procedure will have to be repeated selectively.

Are passwords from Wi-Fi networks and applications transferred?

Passwords from Wi-Fi networks are transferred automatically when restored from a Google backup or through proprietary utilities (provided that password synchronization was enabled on the old phone). Passwords from applications (banks, social networks) are not transferred for security purposes - they will have to be entered again.

Do you need to format a new phone before transferring data?

No, a new phone usually does not require formatting. However, if you bought a used device, it is highly recommended to perform a factory reset (Settings → System → Reset settings) to clear it of the previous owner's data before starting the migration.

What will happen to applications that are not in my region on the new phone?

When restoring from the Google Play Store, applications that are not available in the current region of your new phone (due to geo-blocking) will not be downloaded automatically. You will need to find their APK files manually or change the account region, if possible.
