Changing a smartphone is always an exciting process, which is often overshadowed by the fear of losing important data. When you unpack a box with a brand new product, your first instinct is to start using it right away, but first you need to restore your familiar digital environment. Fortunately, the Android ecosystem has made a huge leap in the convenience of data migration in recent years, making this process almost automatic for most users. Samsung Galaxy or Xiaomi, the first desire is to start using it right away, but first you need to restore the familiar digital environment. Luckily, the Android ecosystem has made huge leaps in the ease of data migration in recent years, making the process almost automatic for most users.
In the modern world, backup no longer requires complex manipulations with the computer and special utilities, as it did ten years ago. Cloud services and direct connections between devices allow you to transfer not only contacts and photos, but also folder structures and Wi-Fi passwords and the applications themselves. However, despite the automation, there are nuances that can lead to the loss of some data if the devices are not properly prepared before starting the procedure.
In this article we will analyze in detail all available migration methods: from standard recovery via a Google account to using proprietary utilities from manufacturers. You will learn how to save progress in games, transfer banking applications without losing settings, and what to do with messenger data, which is often stored separately. Proper preparation will save you hours of time and stress when setting up a new gadget.
Preparing devices for the transfer procedure
Before initiating the data transfer process, you must make sure that both devices are in good condition and ready for use. It is critical to check the battery level on both smartphones, as the process of copying large amounts of information can take from 30 minutes to several hours depending on the connection speed and the amount of data. It is recommended to connect both phones to a power source or make sure that the charge is at least 50-60%.
You should also update the operating system on your old device to the latest version available. This ensures compatibility of transmission protocols and correct operation of Google services. Go to Settings → System → System update and install all available packages. On a new phone, when you turn it on for the first time, the system will prompt you to update, but it is better to do this on the old one in advance to avoid errors in synchronizing application databases.
Don't forget to check the availability of free space on the new smartphone. Even if you don't plan to transfer your entire media library, the applications themselves and their cache can take up a significant amount of space. If your new phone has less built-in memory than your old one, you'll have to decide in advance which apps you really need and which you don't need to install. Removing unnecessary junk on your old device before transferring will speed up the process and free up space on the new gadget.
☑️ Ready for transfer
Using a Google account for recovery
The most versatile and reliable way to get your apps back on a new device is to use Google's built-in backup feature. This method does not require cables or special adapters, since all information is stored in the cloud. When you turn on your new phone for the first time and connect to a Wi-Fi network, the system will prompt you to restore your data from a backup. You will just need to enter the username and password for your Google accountthat was used on your old phone.
The recovery process is as follows: after authentication, the system will show a list of available backups with the date they were created. Select the latest version. In the next menu you will be asked to select what exactly you need to restore. By default, applications, call history, SMS, contacts and device settings are marked. It's important to understand that the application files themselves (APKs) are not always stored entirely in the cloud; often only the store link is downloaded Google Playand the download occurs directly to the new device in the background.
If you have many applications, recovery may take a long time. You can continue setting up your phone and using it while apps download in the background.
It's worth noting that not all app data is saved through Google Drive. Developers themselves decide what data to put into cloud storage. For example, progress in games is often saved if the game supports Google Play Games, but local settings for specific utilities may be lost. Banking apps and high-security apps (such as crypto wallets or 2FA authenticators) never transfer their data through the cloud for security reasons - they will have to be configured manually.
⚠️ Attention: When restoring from the cloud, make sure you are using the same Google account. If you create a new account on your phone, old backups will not be visible in the list of those available for restoration.
Wired connection and proprietary utilities
For users who need to transfer a huge amount of data as quickly as possible, or for those who have unstable Internet, a wired connection is the best solution. Many manufacturers, such as Samsung, Xiaomi, Huawei and OnePlus, supply their smartphones with pre-installed proprietary migration utilities. These apps often work faster than cloud services and allow you to transfer data even between devices of different brands, although the functionality may be limited.
For example, Samsung owners use an application Smart Switchthat allows you to connect two phones via a USB-C to USB-C cable (or via an OTG adapter). Once connected, the devices will recognize each other and you can select the category of data to transfer. The advantage of this method is that it copies not only application shortcuts, but also, in many cases, their internal data, settings and even the location of icons on the desktop. This creates an almost complete copy of the interface of the old phone on the new one.
What to do if there is no native cable?
If the kit does not include a cable to connect two phones (USB-C to USB-C), you can use a regular cable from the old phone and an OTG adapter. Insert the cable from the old phone into the adapter, and connect the adapter to the new phone.
For devices of other brands, there are universal solutions, such as an application Copy My Data or built-in functions in the Android settings (from version 10 and higher). When setting up a new Android 12 or later phone, the system will offer to copy apps and data from any other Android device nearby using a high-priority wireless connection that is faster than regular Wi-Fi. However, cable always remains the most stable option, eliminating interruptions due to interference on the air.
| Manufacturer | Utility name | iOS support | Connection type |
|---|---|---|---|
| Samsung | Smart Switch | Yes (partially) | Cable / Wi-Fi / PC |
| Xiaomi / Redmi | Mi Mover | Yes | Wi-Fi Direct |
| Huawei / Honor | Phone Clone | Yes | Wi-Fi Direct |
| OnePlus / OPPO | Clone Phone | Yes | Cable / Wi-Fi |
Transferring data from instant messengers and social networks
Messengers occupy a special place in the data structure of a smartphone, as they contain the history of correspondence, media files and important documents. Standard Android backup methods often don't touch messenger databases due to their encryption and large size. Therefore, for applications such as WhatsApp, Viber and Telegram, you need to perform separate saving procedures within the applications themselves before moving to a new phone.
In the case of WhatsApp, the process critically depends on whether you use Google Drive for backups. Go to the messenger settings on your old phone, select the section Chats → Chat backup and click the "Backup" button. Make sure your settings indicate saving to Google Drive and not just locally to your device. When you install WhatsApp on a new phone and enter the same number, the system will automatically detect a backup copy in the cloud and offer to restore your message history.
Restoring WhatsApp is only possible if you use the same phone number and the same Google account (or iCloud for iPhone) that were used to create the backup.
The situation with Telegram is much simpler, since this messenger is completely cloud-based. You just need to install the application and log into your account - all chats, channels and media (with the exception of secret chats) will be loaded automatically. Secret chats are tied to a specific device and are not transferred, which the system will warn you about in advance. Viber also requires creating a local or cloud backup through the app settings before changing the device, otherwise the correspondence history will be lost.
⚠️ Attention: When transferring instant messengers to a device with a different operating system (from Android to iOS or vice versa), standard methods may not work. Use official migration tools, such as "Move to iOS" or functions within the applications themselves, if they are available for cross-platform migration.
Features of migrating banking applications and authenticators
Financial security requires special approaches to data migration. Banking apps (Sberbank Online, Tinkoff, Alpha Bank and others) and two-factor authentication apps (Google Authenticator, Microsoft Authenticator) never migrate their data through shared backups. This is done intentionally: if an attacker gains access to your backup, he will not be able to immediately access your accounts.
For banking applications, the procedure is always the same: you install the latest version of the application from the official store (or via APK, if the application has been removed from the store due to sanctions, by downloading it from the bank’s official website) and go through the full authorization procedure again. You will need an SMS code or confirmation via push notification on your old device (if it is still active). Make sure in advance that the SIM card has been moved to the new phone or that you can receive SMS to the old number.
The situation with authenticators is more complicated. In Google Authenticator a function for exporting accounts has appeared. On your old phone, go to the menu, select “Transfer accounts” → “Export accounts”. A QR code will appear. On a new phone, when setting up for the first time, select "Import existing accounts" and scan this code. This will allow you to transfer all tokens at once. If you use other authenticators, check for the cloud sync feature in their settings; if it is not there, you will have to link each service again, disabling 2FA on the old device and enabling it on the new one.
What to do if the old device has already been reset?
If you reset your old phone to factory settings, but did not export the authenticator codes, it will be extremely difficult to restore access to your accounts. You will have to use backup codes, which are issued when two-factor protection is enabled, or contact support for each service separately.
Typical errors and solutions
Even if all instructions are followed, users may encounter problems during migration. One of the most common errors is the "Not enough space" message during recovery, even if the new phone has free memory. This may happen because the temporary decompression files take up more space than the data itself. The solution is simple: free up an additional 2-3 GB on the new device before starting the process, or transfer the data in parts.
Another common problem is the process freezing at the "Application Recovery" stage. This often happens when the Wi-Fi connection is unstable. In this case, it is better to abort the process, reboot both devices and try again, perhaps using a cable instead of a wireless connection. It is also worth checking whether the new phone has a power saving mode enabled, which may limit background downloading of data from Google Play.
Sometimes users complain that after the transfer, some applications do not open or crash. This could be due to incompatible Android versions or because the app has been removed from the store and cannot be updated. In such cases, it is recommended to uninstall the problematic application and install it again manually. If an application is critical and no longer supported, you may need to look for its APK file on third-party resources, but do so with caution and check digital signatures.
⚠️ Attention: Settings interfaces and menu item names may vary depending on the Android version and manufacturer's skin (One UI, MIUI, ColorOS). If you do not find the specified option, use the search in the phone settings.
Completing setup and checking data
After the main body of data has been transferred, do not rush to consider the process complete. It is necessary to conduct a thorough inspection of the new device. Go through the list of applications and make sure that all important apps are installed and updated to the latest version via Google Play or Galaxy Store. Check the widgets on your desktop - sometimes after transfer they may not display correctly or show old data.
Pay special attention to notification settings. On a new phone, notification permissions for apps are often reset to default to save battery and privacy. Go to Settings → Applications → Notifications and activate alerts for instant messengers, mail and social networks. Also test your contacts and calendar synchronization by sending a test event or adding a new contact to make sure it appears in the cloud.
Finally, when you are sure that everything is working correctly, you can start wiping your old device. Before selling or giving away your old phone, be sure to perform a full factory reset (Settings → System → Reset settings → Delete all data). This will delete all your personal data, accounts and files, making the device safe for the new owner. Don't forget to also remove the memory card and SIM card if they were not rearranged earlier.
After resetting your old phone, log into your Google account through a browser on your computer, go to the "Security" section and remove the old device from the list trusted devices.
Is it possible to transfer applications if the screen of your old phone is broken?
If the sensor does not work, but there is an image, you can connect a USB mouse via an OTG adapter for control. If the screen is black, but the phone is working, try connecting it to a PC and using the manufacturer's proprietary utility to create a backup, or remotely managing the phone through services like Find My Device, if this option was enabled in advance.
Will paid in-app purchases be transferred?
Yes, if you use the same Google account. All purchases linked to your Google Play account are restored automatically the first time you launch the application on a new device. However, subscriptions purchased through third-party services or directly from the developer may require re-logging into your account within the application itself.
What to do if the new phone is on a different version of Android?
Android is highly backward compatible. Applications that run on the old version of the system will, in the vast majority of cases, work on the new one. Problems can only arise with very old applications that have not been updated by developers for several years and do not support new security standards or screen resolutions.
Do you need to rearrange the SIM card before starting the transfer?
To transfer data via Wi-Fi or cable, a SIM card is not required. However, to activate some applications (especially instant messengers and banking services), you will need to receive an SMS code. It is recommended to move the SIM card to a new phone before setting up basic services, so as not to interrupt the process.
How long does a complete data transfer take?
The time depends on the amount of data and the transfer method. Via the cloud, this can take from 1 to 3 hours (including downloading applications from the Internet). When using a cable and proprietary utilities, the process usually takes 20-40 minutes, even with a large volume of photos and videos.
