Smartphone owners Samsung Galaxy often face the need to use two accounts in one messenger. This may be due to the separation of work and personal communications or the desire to have a backup number for registering with services. The standard Android interface does not always allow you to run two copies of the same application at the same time, but the ecosystem One UI offers built-in tools for solving this task without the need for superuser rights.
Unlike many other manufacturers, the company Samsung implemented the cloning function at the security level, and not just as an add-on on top of the OS. This means that the second account operates in an isolated environment, which provides better data protection and stability. The user does not need to look for dubious modified versions WhatsApp on the Internet, risking infecting the device with malware.
There are three main ways to create a duplicate messenger on devices of the South Korean brand. The first and most reliable method is to use a protected folder Secure Folder. The second option is suitable for those who want quick access from the main screen - function Double messenger. The third method involves using automation via Bixby Routines for advanced scenarios. The specific method you choose depends on your security needs and interface usability.
Using the Secure Folder
The most effective solution for creating a clone is technology Secure Folder. This is an isolated space on your device, protected by a separate password, PIN, or biometrics. Applications installed inside this folder run as completely independent instances. For WhatsApp this means that you can register a second phone number, and it will not interfere with the main account in any way.
To activate this function, you need to go to the device security settings. The path may vary slightly depending on the firmware version, but it is usually located in the Biometrics and securitysection. After enabling the function, a new folder icon will appear on the desktop. This is where you will need to install a second copy of the messenger from the official store Galaxy Store or Google Play.
It is important to understand that the data inside Secure Folder is encrypted separately. This has the added benefit that even if someone unlocks your phone, they won't have access to the second account without additional authorization. However, it is worth considering that notifications from applications inside the folder may come with a lock icon, which helps hide the contents of messages from prying eyes.
⚠️ Attention: When you reset your phone to factory settings or delete a protected folder, all data inside it, including the chat history of the second account, will be irretrievably lost. Be sure to set up backup inside the WhatsApp application itself while in Secure Folder mode.
☑️ Preparing Secure Folder
Dual Messenger function
For those who do not require an increased level of data isolation, the company Samsung offers a built-in function Double messenger. This method is easier to set up and does not require creating a separate protected space. The cloned application is displayed on the main screen with a small orange chain icon, which allows you to instantly distinguish it from the original.
Activation occurs through the app settings menu. You need to find the item Additional functions and select the appropriate section. The system will automatically scan installed apps and offer to create copies for supported social networks. In the case of WhatsApp, the process takes a matter of seconds: after confirmation, the system will automatically install the second instance.
The main difference between this method and Secure Folder is data storage. Both accounts share media storage unless otherwise specified. This is convenient for sharing photos and videos between personal and work profiles, but is less secure if the device is lost. If the phone falls into the wrong hands in an unlocked state, access to both accounts will be open.
If the dual messenger icon does not appear after installation, try clearing the cache of the "Package Installer" application in the system settings.
Comparison of application cloning methods
The choice between a protected folder and standard duplication often raises questions from users. To make your decision easier, we've compiled a comparison table of the key features of both methods. It will help you determine which option is best suited to your specific smartphone use scenarios Galaxy.
| Characteristics | Secure Folder | Double messenger |
|---|---|---|
| Security level | High (separate password) | Standard (access from the main screen) |
| Data isolation | Full (encryption) | Partial (shared storage) |
| Notifications | Hidden or marked with a lock | Displayed as usual |
| Resource consumption | Higher (running an isolated environment) | Lower (native integration) |
As can be seen from the table, Secure Folder wins in matters of confidentiality. If you use a second number to access banking services or confidential work correspondence, this option is the only option. However, it requires unnecessary steps to enter the application every time.
The method Dual Messenger is focused on convenience and speed. It is ideal for situations when you need to quickly respond to a message from a second number without wasting time entering PIN codes. For ordinary users who separate work and play, this level of functionality is usually sufficient.
Automation through Bixby Routines
Owners of modern smartphones Samsung can use a powerful automation tool - Bixby Routines (or “Modes and Scenarios”). Although this feature does not create a technical clone of the application, it allows you to flexibly manage notifications and access to different accounts depending on the context.
You can set up a scenario in which one notification profile is automatically turned on when connected to your home Wi-Fi, and another when connected to a work network. This is achieved through the creation of application shortcuts. In the menu Settings → Additional functions → Modes and scenarios you can create a shortcut that will open WhatsApp from Secure Folder with one touch, bypassing the need to look for the folder icon.
This approach requires deeper customization, but gives maximum control. For example, you can set up a rule: “If the time is from 9:00 to 18:00, then show notifications only from your work account.” This helps maintain a balance between work and personal life without installing unnecessary apps.
Secret notification settings
In Do Not Disturb mode, you can set exceptions so that calls from work account contacts always go through, even when the phone is in silent mode. To do this, add contacts from the second profile to your favorites list.
Third-party applications for cloning
If for some reason the built-in tools Samsung are not suitable for you (for example, on very old models), you can turn to third-party solutions. There are many cloner applications in the store, such as Google Play There are many cloner apps available such as Parallel Space, 2Accounts or Multiple Accounts. They create a virtual space that emulates a second system.
Using such software has its own risks. First, these apps often contain ads and require extensive permissions to access your data. Secondly, the messenger WhatsApp can recognize work in a virtual environment and temporarily block the account for suspicious activity. Unofficial clients do not like messenger security algorithms.
Nevertheless, such utilities can be useful for one-time tasks or testing. When choosing an application, pay attention to the rating and number of downloads. Avoid apps that require root access, as this may violate the warranty and security system Knox on your device.
⚠️ Attention: Official WhatsApp support does not guarantee the operation of the application in third-party clones. If a number is blocked for using unofficial software, restoring access may be difficult or impossible. Use such methods only at your own risk.
Solving problems with notifications and battery
A common problem when using two accounts is increased battery consumption and missed notifications. The Android system strives to optimize power consumption, so it can “kill” clone background processes. To avoid losing important messages, you need to correctly configure the power saving settings.
Go to Settings → Applications, find the cloned WhatsApp (or Secure Folder) and go to the Batterysection. Set the mode Unlimited. This will prevent the system from terminating the application in the background. Also check the notification settings: make sure that the “Mute” or “Hide Contents” checkbox is not checked for the second account.
Another nuance concerns contact synchronization. Often users forget that the cloned application only sees those contacts that are saved in the main phone book. If you want to see the names of the people you are talking to in the second account, make sure that the numbers are saved in the device memory or Google account, and not just in the SIM card, which may not be visible to the isolated space.
For stable operation of two accounts, it is critical to disable battery optimization for both instances of the application and allow auto-start in the device manager.
Frequently asked questions (FAQ)
Is it possible to use one phone number in the main WhatsApp and in the clone?
No, this is technically impossible. One phone number can only be active in one instance of the application at a given time. If you try to register a second account for the same number, the first account will be automatically deauthorized. For two copies to work, two different SIM cards or one number + virtual number are required.
Will WhatsApp Web work for a clone in Secure Folder?
Yes, the WhatsApp Web function is fully supported. However, you will need to scan the QR code with your phone's camera while inside the Secure Folder. Keep in mind that the web version sessions in the clone and in the main application are independent of each other.
Does the cloned application take up a lot of memory space?
The application itself takes up the same amount of space as the original (about 100-200 MB), but the main amount of memory is consumed by media files (photos, videos, voice messages). If you actively use both accounts, the amount of occupied memory will double in proportion to the number of received files.
What should you do if the Dual Messenger function disappears after updating One UI?
Sometimes after major firmware updates, settings may be reset. Check the section Additional functions again. If you don't see the item, make sure your device is officially supported in your region. On some models for the US or European markets, this function may be hidden programmatically.
Is it possible to transfer correspondence history from regular WhatsApp to a clone?
Direct transfer of history between the main application and the clone (especially in Secure Folder) is not provided by standard means. You will have to make a local backup on the main account, move the database file to the clone folder (which is difficult due to encryption) and restore it. It’s easier to start correspondence in a second account from scratch.
