How to copy applications from one Android to another without losing data

Changing a smartphone is always stressful, associated not so much with the loss of the device, but with the fear of losing the accumulated digital life. When you take a new gadget out of the box, you are faced with the task of not just turning it on, but of recreating the familiar ecosystem. How to copy applications from one Android to another without losing data becomes a key question on which the speed of your return to a comfortable rhythm of life depends.

Modern operating systems provide several mechanisms for migration, but not all of them work equally effectively. Some methods transfer only shortcuts, requiring the content to be downloaded again, while others are capable of cloning the system state down to an alarm setting. In this article we will analyze all the available tools, from built-in cloud services to advanced utilities from manufacturers.

Standard migration via Google Account

The most obvious and often recommended method is based on the Google infrastructure. When you first set up a new device, the system will prompt you to log in Google Accountthat was used on the old phone. If you agree, Google servers analyze the list of installed software and offer to restore it automatically.

However, there is an important nuance here: in most cases, only installation files are downloaded (.apk) from the Play Market. Local data, cache, logins and saves inside games often remain on the old device if the developer did not provide synchronization via the cloud. This means that after installation you will have to re-enter passwords and set preferences.

However, for basic system utilities and popular services this method works flawlessly. It ensures that all applications will be compatible with the new version Android and processor architecture. The process starts automatically in the setup wizard when you select the “Copy apps and data” option.

⚠️ Attention: Make sure that app data synchronization is turned on in Google settings on your old device, otherwise the list for recovery may be incomplete.

Manufacturers' proprietary utilities for full cloning

Large vendors understand standard Google tools and develop their own solutions for deep transfer. apps such as Samsung Smart Switch, Xiaomi Mi Mover or Clone Phone from OPPO are capable of transmitting not only applications, but also their internal data, the arrangement of icons on the desktop and even alarm settings.

The work of these utilities is usually based on creating a direct connection between devices via Wi-Fi Direct or a special cable. This ensures high transfer speeds and allows you to bypass the limitations of cloud storage. For example, when switching to a new one Samsung Galaxy, the Smart Switch utility can even transfer the location of widgets and call history.

To use this method, you must install a companion application on both phones. On the old device you select the “Send” mode, and on the new one you select “Receive”. After scanning the QR code, the migration process begins, during which the device screens should not go dark.

Manufacturer	Utility name	Connection type	Migration of application data
Samsung	Smart Switch	Cable / Wi-Fi	Full (including logins)
Xiaomi / Redmi	Mi Mover	Wi-Fi Direct	Full
Huawei / Honor	Phone Clone	Wi-Fi Direct	Full
OPPO / Realme	Clone Phone	Wi-Fi Direct	Partial (depending on the OS version)

Backup via local backups

If cloud methods seem unreliable to you or your Internet connection is unstable, you should turn to local backup. Many Android shells, such as MIUI or OneUI, have a built-in function for creating a complete copy of the system to internal memory or an SD card.

The created backup file contains a folder structure with application data, which can then be physically transferred to a new device. After copying the file to a new phone, the recovery function reads the archive and unpacks the data into the appropriate system directories. This is especially true for instant messengers, which are not always restored correctly via the cloud.

It is important to understand that restoring a local backup on a device of another brand may not work due to differences in the paths to the system folders. This method is ideal when updating a phone within the same manufacturer or line.

⚠️ Attention: When restoring from a local copy on a new device, the operating system versions must be as close as possible, otherwise a database compatibility error may occur.

Where are local backups stored on Xiaomi?

Usually they are located in folder MIUI/backup/AllBackup on the internal storage. The files have the extension .bak and can weigh several gigabytes.

Advanced transfer via ADB and computer

For users who want to have full control over the process, there is a method of using USB debugging and utilities ADB (Android Debug Bridge). This method allows you to download APK files and, in some cases, application data directly to your computer, and then install them on a new device.

The method requires enabling developer mode and USB debugging on both smartphones. Once you connect your old device to your PC, you can use the command to create a backup of a specific application along with the data. The resulting file is then transferred to the new phone and restored with the same command.

adb backup -f myapp.ab -apk com.example.app

After executing the command, a request to confirm the backup will appear on the phone screen. You must enter your password (if required) and click the confirm button. The process may take time depending on the size of the data.

Features of transferring banking applications and instant messengers

Applications with an increased level of security deserve special attention. Bank clients, such as Sberbank Online or Tinkoff, as well as messengers like Telegram and WhatsApp, often block standard data backup methods for security reasons.

When transferring such apps to a new phone, you will most likely have to go through the authorization procedure again. For instant messengers, it is critical to create a backup copy of chats inside the application itself (in the chat settings) in advance, since the system backup may not pick up the encrypted message database.

Some banking applications are tied to a specific device identifier (Device ID). When changing your phone number, the bank's security system may regard the login as suspicious and require additional confirmation by calling the call center or visiting a branch.

⚠️ Attention: Never try to transfer data folders of banking applications manually through a file manager without root access - this will lead to a launch error and possible account blocking by the security service.

Solving compatibility problems and common errors

Even if you follow all the instructions, users may encounter a situation where applications are installed, but do not open or do not work correctly. This is often due to a difference between the versions Android on the old and new device. An app written for Android 10 may not behave correctly on Android 14 due to changes in permissions policy.

Another common problem is lack of space. When doing a bulk restore of hundreds of applications, you may run out of free space at the worst possible time, resulting in corrupted installation files. It is recommended to clear the cache before starting the migration.

If you encounter cyclic reboots or errors after the transfer, try resetting the new phone and migrating selectively, installing only the most necessary apps manually.

Is it possible to transfer applications without the Internet?

Yes, this is possible using proprietary utilities (Smart Switch, Mi Mover) that work through a direct Wi-Fi connection between phones, or through a local backup to an SD card. A Google Account requires a network connection to download apk files.

Are passwords from sites transferred in the browser?

Passwords are transferred only if you used synchronization through a Google Chrome account or another browser. System transfer of application data usually does not affect the browser's secure key store.

What should you do if the application does not start after the transfer?

Try clearing the cache and data of that particular application in the settings. If it doesn’t help, delete it and install it again from the store, since the file could have been damaged during transfer or may not be suitable for the new OS version.

Do you need root access to completely copy data?

For standard methods (Google, proprietary utilities), root access is not needed. They are required only to create full system images through specific software like Titanium Backup, which is not recommended for ordinary users.
