What do dual apps mean in Xiaomi and how to use them?

Owners of Xiaomi, Redmi and Poco smartphones often face the need to maintain multiple accounts at the same time, which may be due to work where you need to separate personal and professional communication, or to the desire to use bonus programs in stores. Dual applications are a system feature of the MIUI shell and the new HyperOS, allowing you to run two independent copies of the same software.

In the past, users had to buy a second phone or use complex workarounds to solve this problem. Now cloning technology is built deep into the system and does not require the installation of third-party programs that often overload RAM. In this article, we will analyze the mechanics of the function, learn how to activate it and answer frequent questions on setting up.

Not all apps support this option, although the list of compatible services is huge, and it determines whether you can create a clone for a particular installation package, if you want to know how two different WhatsApp accounts work on the same device without having to use the same software. SIM-cards in the second slot, this functionality is the key solution.

The essence of cloning technology in MIUI and HyperOS

Known as App Cloner, it creates a virtual copy of the service it selects, and for the operating system, it looks like installing a completely new, independent application with its own unique identifier, and the data inside the clone is stored separately from the original, ensuring that the correspondence, settings, and cache are completely isolated.

Technically, it's at the file system and the registry level, and when you run a clone, it redirects requests to an isolated data container, which means you can get a notification from the main messenger and a second later from a copy of it, and they won't conflict with each other.

⚠️ Note: Clone apps take up extra space in internal memory. If your smartphone has a 64GB drive or less, watch for free space, as the cache of two instances of social networks can quickly exhaust the resource.

Xiaomi has implemented this feature so that it works consistently even on budget models, but it is worth noting that running two heavy programs simultaneously increases the consumption of RAM. On devices with 4 GB of RAM and less, this can lead to more frequent unloading of background processes.

What apps can be cloned on Xiaomi

System constraints allow you to create copies for every installed.apk file. First of all, support is designed for messengers and social networks. The list of supported programs is dynamic and can change with shell updates, but the basic set remains stable for years.

Users usually use cloning for the following services:

• 📱 Messengers: WhatsApp, Telegram, Viber, Signal.
• 📸 Social networks: Instagram, VKontakte, Facebook, TikTok.
• 💬 Communication platforms: Skype, Discord, Zoom.
• 🛒 Marketplaces and Banks: Some Bank and Store Apps May Also Be Duplicated.

To check whether a particular program supports copy creation, just go to the settings of the function. If the application is not in the list of available for cloning, then its architecture does not allow you to work in multi-account mode or Xiaomi developers did not add it to the whitelist.

Interestingly, some games also make it to this list, which allows gamers to make two game progresses on the same device, switching between them without constantly logging out and re-authorizing, but for games this works less stable than for instant messengers.

Step-by-step: how to enable dual applications

Activation of the function takes less than a minute and requires no complicated manipulation. The interface of settings in MIUI 12/13/14 and HyperOS is almost identical, so the instruction will be universal for most modern smartphones of the brand.

Follow the following steps to start the process:

1. Open the standard Settings app on your smartphone.
2. Scroll down the list and find the App section.
3. In the menu that opens, select Cloning of Applications (in some versions it may be called Double Applications).
4. You'll see a list of installed programs. Find the one you want and click the switch next to it.
5. The system will create a shortcut with a small copy icon (usually a yellow badge in the corner of the icon).

Once turned on, a second icon will appear on the desktop, which will look exactly like the original, but with a distinctive marker, and now you can open it, enter data from the second account, and use both profiles in parallel.

If you use mobile data, the traffic will add up, and notifications from the clone may come with a slight delay if the system decides to optimize power consumption.

Set up notifications and manage accounts

Once a copy is created, many users experience notification confusion, and sound and vibration can come from both accounts the same way, making it difficult to know where exactly the message came from, and fortunately, the system allows for flexibility in configuring this aspect.

To separate notifications, do the following:

Go to Settings → Applications → App Cloning. Click on the settings icon (cogs) in the upper right corner of the screen. Here you can turn on the option “Use different notification sounds.” Once activated, the clone will notify events with a unique signal other than the main application.

Notification management is also available via a quick access curtain. If one of the applications is blocked, notifications may not come. Check the battery settings for both experiences, setting the "No Limits" mode so that messages are delivered instantly.

💡

To quickly distinguish messages, assign a specific sound to the WhatsApp clone, such as the sound of a mailbox, then you will immediately understand what the second account is writing without even looking at the screen.

Problems with security and access to data

The use of dual applications raises questions about data security, because the clone is isolated, it has its own permissions, which means that when you first set up, you'll have to re-allow the microphone, camera and geolocation for the second copy.

There are certain nuances that you should know about:

• 🔒 Application Lock: App Lock works independently for the original and clone. You can only put a password on the clone, leaving the main one open, or protect both.
• 📂 File access: Both apps see a shared file system.Photos saved from a WhatsApp clone can appear in a shared gallery if album separation is not configured.
• 🚫 Banking applications: Some banking services may block active cloning devices as a sign of a modified system or a security threat.

⚠️ Warning: Do not use cloned applications to access critical bank accounts or government services unless urgently needed. The risk of data leakage through cloning vulnerabilities is minimal, but theoretically higher than in the native environment.

Also worth mentioning is Second Space, a deeper level of isolation that creates a completely separate desktop environment. Unlike simple cloning, Second Space requires a separate login (fingerprint or password) and hides all data from the main profile.

Removing cloned applications and cleaning up

If the need for a second account is no longer needed, the clone can be easily removed.The deletion process is slightly different from the standard uninstallation to prevent the main application from being accidentally erased.

To remove, follow the following steps:

Go to Settings → Applications → App Cloning. Find the program you want to delete in the list and turn off the switch. The system will request confirmation to delete the clone data. Once confirmed, the shortcut will disappear from the desktop and the main application will remain intact.

Remember to periodically clear the cache of cloned applications. Because they work independently, automatic garbage cleaning may not affect them. Go to the memory management of the phone and select the cleanup for the specific clone to make room.
