How to transfer an installed app from one Android to another: a complete guide

Transferring installed applications from one Androiddevice to another is a task that every user faces when purchasing a new smartphone or tablet. Unlike iOSwhere the Apple ecosystem synchronizes data automatically, Android offers more, but also requires manual actions. The problem becomes more complicated if you need to save not only the application itself, but also its settings, progress in games or local data - for example, downloaded maps in Google Maps or offline dictionaries.

In this article we will analyze all the current methods of transferring apps - from standard functions Google Play to advanced methods using ADB i root access. We will pay special attention to the nuances: why some applications are not transferred, how to bypass manufacturer restrictions (for example, Xiaomi or Samsung), and what to do if the app does not start after transfer. You will also learn how to avoid data loss when moving to a new device and what tools will help automate the process.

1. Standard transfer via Google Play: pros and limitations

The easiest way is to use the built-in synchronization function Google Play. It is available on all devices with Android 5.0+ and does not require additional apps. When you start a new smartphone for the first time, the system will offer to restore data from the old device, including a list of installed applications. However, this method has serious limitations:

• 📌 Only third-party APKs (for example, downloaded from applications from Google Play - third-party APKs (for example, downloaded from APKMirror) will have to be installed manually.
• 🔄 Not saved settings and local data most apps (with the exception of games with support Google Play Games).
• 🚫 Some manufacturers (for example, Huawei without Google services) may block this function.

To use the standard transfer:

1. On the old device, check that synchronization is enabled: Settings → Accounts → Google → Account synchronization.
2. On the new device, when setting up, select the option "Copy data from old device" and follow the instructions.
3. If the device is already configured, go to Settings → Google → Recovery and reset → Application recovery.

⚠️ Attention: When restoring via Google Play Some applications (for example, banking or DRM-protected) may require re-authorization.

2. Backup and transfer APK files manually

If the standard method is not suitable, you can extract APK files installed apps and transfer them to a new device. This method works for any applications, including those that are not available in Google Play. To extract APK you will need a file manager with rights root (for example, Root Explorer) or specialized utilities like APK Extractor.

Step-by-step guide:

1. Install on the old one device APK Extractor (available in Google Play).
2. Run the app and select the applications you want to keep. The files will be saved in a folder /sdcard/ExtractedApks/.
3. Copy the APK to a new device (via Bluetooth, cloud or cable) and install them manually, allowing installation from unknown sources (Settings → Security → Unknown sources).

Advantages of the method:

• 📦 Works for any applications, including system and modified ones.
• 🔧 Does not require an Internet connection after copying files.

Disadvantages:

• 🚫 Application data is not saved —only APKs themselves.
• 🔒 On new versions Android (11+) installation problems may occur due to restrictions scoped storage.

Make sure that the Android version on the new device is compatible with APK

3. Transferring applications with data: Titanium Backup and analogues

For a complete transfer applications along with data (settings, cache, progress in games) you will need apps with advanced backup functions. The most famous is Titanium Backup, but it only works on devices with root access. Alternatives for non-rooted devices (for example Helium) often have limitations.

Instructions for Titanium Backup:

1. Install the app and provide root access.
2. Select a tab "Backups" and mark the desired applications.
3. Click "Save" and wait for the process to complete. The files will be saved in the folder /sdcard/TitaniumBackup/.
4. Move the folder to the new device, install Titanium Backup and restore the data through the menu "Recovery".

Important nuances:

• 🔐 Not all data will be restored —some applications (for example, WhatsApp) store critical files in protected folders.
• 📱 On new devices with Android 10+ may require additional setting permissions for Titanium Backup.
• 🔄 When restoring, select the option "Data + APK"to transfer both the app and its settings.

⚠️ Attention: When restoring system applications on devices Samsung or Xiaomi failures are possible due to modified manufacturer firmware. Before transferring, check compatibility on the forums (for example, XDA Developers).

app	Requires root	Transfers data	Supports Android 12+
Titanium Backup	✅ Yes	✅ Yes (completely)	⚠️ Partially
Helium	❌ No	⚠️ Partially	❌ No
Swift Backup	✅ Yes	✅ Yes	✅ Yes
APK Extractor	❌ No	❌ No (APK only)	✅ Yes

4. Using ADB to transfer applications (without root)

If no root accessbut you need to transfer an application with data, you can use the tool ADB (Android Debug Bridge). This method works on most devices, but requires enable USB debugging and installation ADB drivers on the computer.

Step-by-step guide:

1. Enable USB debugging on the old device: Settings → About phone → Build number (press 7 times), then Settings → System → For Developers → USB Debugging.
2. Connect the device to the PC and run the command to extract the APK and data:

   adb backup -f backup.ab -apk -obb -shared -all

   On the device, confirm the creation of a backup.

3. Copy the file backup.ab to a new device and restore the data:

   adb restore backup.ab

Method limitations:

• 🔒 Not all applications support backup via ADB (depends on the flag android:allowBackup in the manifest).
• 📱 On some devices (for example, Xiaomi c MIUI) ADB backup may be disabled by the manufacturer.
• 🔄 Restoration is only possible on a device with the same or newer version Android.

adb backup -f whatsapp.ab -apk com.whatsapp

Batch names can be found through app App Inspector or command adb shell pm list packages.-->

5. Transfer through cloud services and third-party launchers

Some cloud services and launchers offer functions for synchronizing installed applications. For example:

• 🌥️ Google Drive + Smart Switch (for devices Samsung) - transfers the list of applications and part of the data.
• 📱 Nova Launcher - saves desktop settings and the list of applications (but not the APKs themselves).
• 🔄 Mi Mover (for Xiaomi) - copies applications between devices Xiaomi/Redmi/Poco by Wi-Fi.

Example of transfer via Smart Switch:

1. Install Smart Switch on both devices (available in Google Play i Galaxy Store).
2. On the old device, select "Send data"on new — "Receive data".
3. Connect devices via cable or Wi-Fi and select "Applications" in the list of data to transfer.

Advantages of cloud methods:

• 🔗 Does not require root or ADB.
• 📡 Works wirelessly (via Wi-Fi or cloud).

Disadvantages:

• 🚫 Transferred not all applications only those supported by the service.
• 📦 Application data (for example, game saves) may not be copied.

How to transfer data WhatsApp without root?

1. Back up your chats in WhatsApp: Settings → Chat → Backup.

2. data-i="209">to a new device (via PC or cloud). /sdcard/WhatsApp/ to a new device (via PC or cloud).

3. Install WhatsApp on a new device and restore the data on the first launch.

⚠️ Important: The folder name must be the same (case sensitive), and the phone number must remain the same the same.

6. Transfer of system applications and applications with DRM

System applications (for example, Google Camera to Pixel or proprietary utilities Samsung) and apps with DRM protection (for example, Netflix, bank clients) are more difficult to transfer. Here's what you need to consider:

• 🔐 System APK are often tied to the firmware - transferring them to another device can cause crashes.
• 🎬 Applications with DRM (for example Disney+ or Sky Go) require device certificates that are not portable.
• 📱 On devices with Android 11+ system applications are protected by a mechanism APK Signature Scheme v3that makes them copying is impossible without modification.

Solutions for complex cases:

• 🔧 For system applications, use Titanium Backup with the option "Freeze before deletion" (root required).
• 🌐 For DRM applications, the only reliable way is installation from the official store (Google Play or Galaxy Store) with subsequent authorization.
• 📦 If you need to transfer a modified application (for example, Google Camera with ported functions), look for a version adapted for your device model on the forums XDA or 4PDA.

⚠️ Attention: Transferring system applications to devices of other brands (for example, Samsung Camera to Pixel) often leads to errors due to library incompatibility. At best, the app will not start, at worst, it will cause system failures.

7. Transfer automation: scripts and tasks

For users who regularly transfer data between devices, it is useful to automate the process using scripts. For example, you can create bash script for ADBwhich will extract APK and data of selected applications in one click.

Example script for backing up all user applications:

#!/bin/bash
for pkg in $(adb shell pm list packages -3 | cut -f2 -d:); do
adb backup -f"$pkg.ab" -apk -obb -shared"$pkg"
done

For recovery:

#!/bin/bash
for file in *.ab; do
adb restore"$file"
done

Automation tips:

• 📝 Compile list of critical applications and their package names in advance.
• 🔄 Use Tasker to create tasks to copy APK when connected to a specific Wi-Fi network.
• 📊 To monitor the process, connect notifications via Telegram Bot or Pushbullet.

Frequent errors and their solutions

When migrating applications, users encounter typical problems. Here are the most common ones and how to solve them:

Error	Cause	Solution
"Application not installed"	Version incompatibility Android or processor architecture (arm/x86)	Check APK compatibility via APKMirror or use universal versions (universal apk)
Data not restored	The application does not support backup or has changed UID	Try Titanium Backup with the option "Fix recovery" or transfer the data manually
"Package parsing error"	Damaged APK file or incorrect signature	Reload the file and check its hash sum (MD5), if necessary, download again
The application starts but crashes	There are no dependencies or incompatibility with the firmware	Install missing libraries (for example, Google Play Services) or look for an alternative APK version

If none of the methods worked:

• 🔍 Check error logs via adb logcat —they will tell you the exact cause of the failure.
• 📱 Try to transfer the application to a device with the same version Android and processor architecture.
• 🌐 Refer to thematic forums (for example, XDA Developers or 4PDA) - there are often solutions for specific models devices.

❓ Is it possible to transfer an application with data without root and ADB?

Yes, but with serious limitations. Some applications (for example Helium or Swift Backup) offer backup without root, but:

• Requires connection to a PC and installation of additional drivers.
• Not all applications are supported (depending on the flag android:allowBackup).
• On Android 10+ the effectiveness of such methods drops sharply due to limitations scoped storage.

For most users without root, the best option is to use cloud services (for example Google Drive to backup data of specific applications, if they support it).

❓ Why after the transfer application asks for re-authorization?

This is due to security mechanisms:

• Access tokens often tied to a specific device (for example, in banking applications or WhatsApp).
• Device identifiers (Android ID, IMEI) change, which resets the session.
• DRM protection (for example, in Netflix or Spotify) requires re-verification of the license.

Solution: Log in again If there is a problem. is saved, delete the application data (Settings → Applications → Storage → Clear data) and try again.

❓ How to transfer an application from Android to iOS?

Direct transfer of APK files from Android to iOS is not possible due to fundamental differences in system architecture. However, there are workarounds:

• 🔄 Use cross-platform services (for example, Google Drive for documents, Spotify for music).
• 🎮 For games with cross-platform support (for example, Genshin Impact) link your account to email or social network.
• 📱 Some applications (for example, WhatsApp) offer official tools for transferring chats from Android to iPhone (but not vice versa!).

For most applications you will have to install iOS-version from App Store and configure it again.

❓ Is it possible to transfer the system application to another device?

Technically yes, but with reservations:

• 📱 On the same device (for example, after a reset) - it can be restored via Titanium Backup or ADB.
• 🔧 To another device of the same brand (for example, Samsung Galaxy S21 → Galaxy S22) - sometimes it works, but failures are possible.
• ❌ To a device of another brand (for example, Samsung → Pixel) - almost always leads to errors due to dependencies on proprietary libraries.

System applications often use the manufacturer’s closed APIs, so transferring them to other devices is fraught with unstable operation.

❓ How to transfer progress in the game if it does not synchronize with the cloud?

If the game does not support Google Play Games or its own cloud save, try:

1. Find the save folder (usually /sdcard/Android/data/[game package]/ or /data/data/[game package]/ for root).
2. Copy it to a new device in the same location.
3. If the game uses obfuscated data (for example, Clash of Clans), may be required Titanium Backup with the option "Recover data".

For some games (for example, Minecraft) saves are stored in files with the extension .mcworld —they can be transferred manually.
