Many owners of Samsung Galaxy smartphones, when studying the settings of their device or viewing the list of installed apps, are faced with an incomprehensible term Separated Apps. In the Russian version of the interface, this is often translated as “Split applications” or associated with the messenger cloning function. A logical question arises: is this a separate app, a virus or a system error that needs to be removed urgently?
In fact, Separated Apps is not a third-party application that can be downloaded from the Internet, but a built-in system shell mechanism One UI. It is responsible for creating an isolated space for duplicate apps, allowing you to use two different accounts in one messenger at the same time. Understanding how this function works will help you competently manage your phone memory and increase your digital security without installing dubious software.
In this article, we will analyze in detail the architecture of the operation of separated applications on devices Samsung, we will find out in which cases this function is really necessary, and when it is better to abandon it. We will also look at the technical nuances that affect the performance of a smartphone and give clear instructions on how to manage this tool.
The essence of application separation technology on Android
The technology behind the name Separated Apps, is an advanced virtualization system at the operating system level. When you activate the cloning function for a specific messenger, the system does not just create a shortcut, but deploys a full-fledged isolated container. Inside this container, a second copy of the application is launched with its own data storage, cache and settings.
This means that for the Android system, these two copies are perceived as completely different apps with unique identifiers. Separated Apps ensures that the data from the main account does not in any way overlap with the data of the cloned version. Such isolation is critical to protecting personal correspondence, especially if several people use the same device or if you separate work and personal profiles.
It is worth noting that this function is deeply integrated into the shell One UI and is closely related to the operation of the service Knox. This provides an additional layer of security by preventing data leakage between separated spaces. Unlike third-party clone apps that often require suspicious permissions, system partitioning works at the kernel level, making it a more stable and secure solution.
⚠️ Warning: Partitioned apps take up additional memory space. Each copy stores its own media cache, so the total amount of space occupied can increase by one and a half to two times compared to using one account.
Before activating separation for heavy messengers like Telegram or WhatsApp, make sure that your device has at least 3-4 GB of free internal memory for comfortable work.
Differences from Dual Messenger and Secure modes Folder
Users often confuse the concept Separated Apps with a function Dual Messenger, although technically they solve similar problems in different ways. Dual Messenger is a user interface that allows you to quickly create a copy of a popular instant messenger with one click. At the same time, Separated Apps is a more general system term that describes the isolation mechanism itself, which can be used not only for instant messengers, but also in other scenarios, for example, in Secure Folder (Secure Folder) mode.
Mode Secure Folder creates a fully encrypted space on the device, access to which is protected by a separate password or biometrics. Applications installed inside the Secure Folder are also “separated” from the main system. You can have two WhatsApp icons: one in the regular menu, the other inside a folder, and they will work independently of each other, using different phone numbers for verification.
The main difference is the level of access and visibility. The clone via Dual Messenger is visible in the general list of applications and works in the background along with the main app. Applications inside Secure Folder are hidden from prying eyes and require additional authentication to run. The system Separated Apps is the foundation on which both of these functions are built, ensuring their correct operation without conflicts.
| Characteristics | Dual Messenger | Secure Folder | Third-party clones |
|---|---|---|---|
| Security level | Standard | High (Knox) | Low |
| Icon visibility | Visible in the general menu | Hidden in the folder | Visible in the general menu |
| Notification support | Full | Only when unlocked | Frequently crashes |
| Impact on the battery | Moderate | Minimum in the background | High |
Use Dual Messenger for quick access to a second account, and choose Secure Folder if you need to hide the presence of a second application from prying eyes.
Why does the average user need separated applications
For most smartphone owners Samsung the need to use separated applications dictated by the way of life and work. In the modern world, digital hygiene requires separation of personal and work contacts. Having two active instant messengers on one device eliminates the need to carry a second phone, which greatly simplifies life for freelancers, entrepreneurs, and sales managers.
In addition, this feature is useful for family use. Parents can configure the smartphone so that the child has access to certain games or educational applications in an isolated environment, without access to the parents' main accounts. The mechanism Separated Apps prevents accidental deletion of important data or making in-app purchases from the main profile.
Another use case is software testing. Developers and advanced users can install beta versions of applications in a shared space to test new functionality without risking the stability of the main version of the app. If the test version contains errors or viruses, the main profile remains completely safe thanks to isolation.
- 📱 Ability to use two WhatsApp or Telegram numbers simultaneously without switching SIM cards.
- 🔒 Isolation of banking applications in a protected environment for increased payment security.
- 🎮 Launching multiple game accounts in MMO projects on one device.
- 👥 Providing limited access to the smartphone to children or employees.
⚠️ Attention: Not all applications support the cloning function. System restrictions may prohibit the separation of banking apps or applications with increased security requirements.
Impact on the performance and autonomy of the smartphone
Activating the application separation function inevitably leaves its mark on the device’s resources. Since two independent processes are essentially launched, RAM consumption (RAM) increases. If your smartphone has less than 4 GB of RAM, the simultaneous operation of two heavy messengers can lead to more frequent downloading of background tasks and slower switching between apps.
As for the processor, modern chips Exynos and Snapdragoninstalled in Samsung Galaxycan easily handle with load. However, if both instances of the application are actively used at the same time (for example, there is a video call in one account and downloading files in another), the case may heat up and the battery may drain faster. The system automatically adjusts processor frequencies, but the physics of the process remains unchanged: more tasks - more energy.
It is also important to consider the impact on storage. As mentioned earlier, the app split cache is not shared (not shared). Photos received in work chat will take up space separately from photos in personal chat. Over time, this can quickly fill up the internal memory, especially if you actively share media files.
Technical details of working in the background
The Android system uses a different UID (User ID) for each clone of the application. This means that processes cannot access each other's files directly without special permissions, which creates additional disk I/O load when syncing large amounts of data.
How to manage and disable split applications
The cloning function is controlled through the standard settings menu. To activate or deactivate split apps, the user does not need superuser rights or a computer connection. All actions are performed intuitively through the shell graphical interface One UI.
To enable the function, you need to go to the section Settings, then select the item Additional features and find there Dual Messenger. The list that opens will display all supported applications. The switch opposite the desired app activates the creation of a second copy. A new icon will then appear on your desktop with a small orange chain icon indicating that it is a clone.
If you decide you no longer need a feature, the process of disabling it is just as simple. Entering the menu again Dual Messenger and turning off the switch will start the process of deleting the cloned application. The system will warn you that all data accumulated in the second copy (correspondence, media files, settings) will be permanently deleted.
☑️ Check before deleting a clone
Settings → Additional features → Dual Messenger → Turn off the switch⚠️ Attention: When you delete a split application, the correspondence history in the second account is completely erased. It can be restored only if you have a previously created backup copy in the cloud storage of the messenger itself.
Possible problems and ways to solve them
Despite the stability of the system Separated Apps, users may encounter a number of typical problems. One of the most common is the lack of notifications from the cloned application. This is often associated with aggressive power saving settings that "put to sleep" the background process of the second copy, considering it a lower priority.
To solve this problem, you need to go to the battery settings and find the corresponding cloned application (it will be marked with a chain icon). In the battery usage settings, select the mode Unlimited or Optimized, but with mandatory permission to work in the background. It is also worth checking the notification settings, since they are configured independently for the main and split applications.
Another problem is version conflicts. Sometimes after updating the main application, the clone may stop starting or work incorrectly. In such cases, it is recommended to first update the main version, wait for stabilization, and then check for updates for the clone in the store Galaxy Store or Google Play. In rare cases, a complete reset of the clone settings through the app management menu helps.
- 🔋 Check the power saving settings for the second copy of the app.
- 🔔 Make sure that notifications are not blocked in the "Notifications" system menu.
- 🔄 Update both applications to the latest available version.
- 🗑️ In case of critical errors, delete the clone and create it again.
Most problems with split applications can be solved by correctly setting permissions to run in the background and disabling aggressive battery optimization.
Is it possible to split any application on Samsung?
No, the function Dual Messenger only supports a certain list of applications, mainly popular instant messengers and social networks (WhatsApp, Telegram, Facebook, Messenger, Viber, Line). System applications, banking software and many games do not support official cloning due to security restrictions or the technical impossibility of two copies working correctly.
Deleting a clone will delete the main account?
No, these are completely independent processes. Deleting a split application (clone) only affects the data on the second copy. Your main application, its entire chat history and settings will remain completely intact. The system clearly demarcates these spaces.
Why is the chain icon on the application icon orange?
The orange chain icon is a proprietary visual marker of the shell One UI, indicating that this application is a clone created through the function Dual Messenger. This indicator helps the user visually distinguish a work account from a personal one and not get confused when choosing a app for a call or message.
Does the separation of applications affect the warranty of the smartphone?
No, the use of built-in system functions, such as Separated Apps, Dual Messenger or Secure Folder, is normal operation of the device. This is not considered interference with the software (as, for example, obtaining root access) and in no way voids the manufacturer's warranty. Samsung.
Is it possible to transfer data from the main application to a clone?
There is no direct way to transfer correspondence history from the main account to a cloned one within the system, since they are considered different users. However, you can use the standard backup functions of the messenger itself (for example, a WhatsApp backup to Google Drive), restoring it when you initially set up the clone if you need to transfer the history to a new number.
