Xiaomi smartphone owners often face the need to use multiple accounts on the same messengers or social networks. The standard Android operating system by default does not allow you to install the same application twice, which creates inconvenience for those who combine work and personal life on the same device. However, the company’s engineers have developed an effective solution to this problem, which is available right out of the box without the need to obtain superuser rights or flashing.
App cloning in the Xiaomi ecosystem is a software feature that allows you to create a full copy of the installed software. This copy works as an independent application with its own data, settings and account binding. You can receive notifications from both accounts at the same time, and they will not conflict with each other, since the system isolates their processes.
In this article, we will take a closer look at how this mechanism works, how it differs from creating additional space, and what the limitations are, and how to properly configure this feature to maximize productivity and not lose important data when resetting.
Dual Apps Technology in MIUI and HyperOS
Known as Dual Apps (or Dual Apps), the feature is part of MIUI’s proprietary shell and now the new HyperOS. It relies on a process isolation mechanism that allows the system to think that the cloned application is a completely different software product, and to do so, the operating system assigns a unique package ID to the clone that is different from the original.
When you create a clone, for example, for WhatsApp or Telegram, the system actually deploys a second instance of the runtime, which means that the cache, message databases, and authorization files are stored in a separate directory, which is why you can log into the cloned application from another phone number, and it will work in parallel with the main one.
It is important to understand that cloning only affects certain compatible applications, the list of supported software is limited primarily to social networks and messengers, as they most often require multi-accounting.
⚠️ Attention: Clone applications consume additional RAM resources. If your smartphone has less than 4 GB of RAM, activating a large number of clones can lead to a noticeable decrease in the performance of the device.
💡
Use the cloning feature only for applications that do require constant access to a second account to avoid overloading the system.
The technology works at the core level of the system, which provides high stability. Unlike third-party launchers or virtual environments, the built-in mechanism Xiaomi does not require a constant background process-intermediary, which could drain the battery.
Dual Apps differs from Second Space
Many users confuse Dual Apps with Second Space, but these are fundamentally different tools with different use cases. Dual Apps creates copies of individual applications within the current user profile, keeping a single gallery, contacts and a common file system for both instances.
Second Space creates a completely isolated environment, almost like a second smartphone inside the first. In that space, you'll have your own separate lock screen, your photos, your contacts, and your set of apps. Switching between the main and second spaces is through a special shortcut or fingerprint assigned to quickly log in.
- 🔐 Data isolation: Second Space completely hides files and applications from the main profile, while Dual Apps allows access to files.
- 📱 Dual Apps just adds an icon with a tag, and Second Space changes the entire desktop to an alternative one.
- ⚙️ Settings: In the Second Space, system settings (sound, screen, network) are independent, in Dual Apps they are shared.
If your goal is to have two WhatsApps, you need Dual Apps, and if you want to completely hide certain apps, photos, or browser history from prying eyes by creating a separate, secure profile, then you should use Second Space.

Step-by-step instructions for creating clones of applications
The process of activating the function is as simple as possible and takes only a few seconds. You do not need special knowledge or connection to a computer. All actions are performed through the standard menu of smartphone settings.
You first need to go to Settings and find the App item, and in some firmware versions, this tool is put into a separate application called Dual Apps or Dual Apps right on the desktop or in the Tools folder.
☑️ Activation algorithm
Once you activate the switch in front of the app you want (like Facebook or Instagram), the system will automatically create a copy of it, and a new icon will appear on the desktop, which will be marked with a special icon, usually in the form of an orange ring or the number "2", so you do not confuse it with the original.
You'll need to go through the authorization process again to work with the clone. If you're using a messenger tied to a phone number, make sure that you're using it. SIM-The second number card is active for reception SMS-confirmation.
| Annex | Support for Dual Apps | Features of work |
|---|---|---|
| Complete. | Requires a separate phone number | |
| Telegram | Complete. | Can work with a single number (cloud mode) |
| Viber | Complete. | Second one is needed. SIM-map |
| Complete. | Convenient for separating personal and work accounts | |
| Banking applications | No (standard) | Security system is blocked |
It is worth noting that the list of supported applications can vary depending on the regional version of the firmware (Global, China, EEA). In Chinese versions MIUI list is often wider.
Advanced capabilities: Cloning arbitrary applications
The standard Dual Apps list is limited to the developer, but advanced users may want to clone apps that aren’t on this list. To do this, the feature settings often include the option to Create a dual application (or “Add an application”), which allows you to forcefully create a clone for any installed application. APK-file.
When using this feature, the system warns of possible instability, because not all applications correctly handle running in an isolated environment, some may not receive push notifications, others may fly out when you try to log in.
To take advantage of this opportunity, look for the add button (usually a plus in the corner of the screen of the list of Dual Apps), the system will scan the installed packets and suggest creating a clone for those that are technically capable of running in emulation mode.
⚠️ Cloning of financial applications or highly secure services (Google Pay, bank clients) may result in access blocking due to the integrity of the runtime.
If Xiaomi’s standard tools fail to create a clone, users often turn to third-party solutions such as Parallel Space or 2Accounts. These applications create a virtual environment that emulates Android inside Android, which allows you to run almost any program in several instances, albeit at a high cost of resources.
Problems with notifications and background work
One of the common problems with cloned applications is the aggressive battery optimization characteristic of MIUI and HyperOS. The system can "kill" the background clone process to save charge, which causes you to stop receiving messages until the application is manually opened.
To avoid losing important notifications, you need to set the power saving for the cloned application correctly. Go to Settings → Battery and Performance (or through the settings of the application itself) and select No Limits mode, which will prevent the system from forcibly stopping the process.
- 🔋 AutoRun: Make sure the AutoRun menu includes a switchboard for the cloned application.
- 🔔 Notifications: Check that notification settings allow all types of pop-up messages and beeps.
- 🔒 Lock in memory: Open the menu of running applications, find a clone, pinch it and press the lock to lock in RAM.
Also, it is worth considering that having two active instances of a heavy application, such as a video editor or a navigator, can cause the case to heat up, in which case the system can automatically limit the frequency of the processor.
💡
For stable operation of notifications in the clone, be sure to remove all restrictions of background activity and fix the application in RAM.
Data security and clone removal
The issue of cloning security is often a concern for enterprise users, because the data in the clone is stored in an encrypted form, isolated from the main application, but if you decide to remove the clone, all the data inside the clone will be irretrievably lost.
When you remove the main application, the clone will also be automatically removed by the system. The inverse relationship does not always work the same way: removing the clone does not affect the original, but when you reset the settings to the factory (Hard Reset), both instances are deleted.
It is recommended to back up chats and important data regularly, especially if you use a clone for work correspondence. In messengers like WhatsApp and Telegram, use built-in cloud backup features, linking the clone to a separate Google Drive or iCloud account.
If you transfer the phone to another person or sell it, simply removing the icons is not enough: you need to perform a full reset or use the Clear All Data function for each cloned application separately through the storage management menu.
