Second Space in Xiaomi: A Complete Guide to Setup a Hidden Profile

Modern smartphones have long since ceased to be just devices for calls, becoming a digital extension of the person, where work documents, personal correspondence and entertainment content are stored. Owners of Xiaomi devices often face the need to clearly separate these areas so as not to mix work chats with personal or restrict children’s access to certain applications. The standard solution of multiple Google accounts can be inconvenient, as it requires constant switching.

And for these scenarios, the engineers at MiUI and the new HyperOS shell have developed a unique feature called Second Space, which allows you to create, in fact, another, completely isolated smartphone inside a single phone with its own settings, passwords, and application set, not just a limited-access folder, but a full-fledged environment running parallel to the main system.

In this article, we will explore how to activate this mode, how it differs from a guest profile, and how to effectively manage data between two worlds. You will learn about the intricacies of working with two Google accounts simultaneously and understand how to hide the fact that there is additional space from prying eyes.

What is the Second Space and How Does It Work?

The second space is software virtualization technology, which creates an isolated environment on the device, and when you switch to that mode, the phone looks and behaves like a new device: it has a clean desktop, its widgets, its gallery, and its audio settings. For the system, it's two different users whose data doesn't overlap without your explicit permission.

The main advantage is that applications running in the second space don't have access to files, contacts, or the history of the primary browser, which is ideal for creating a work phone where you can install corporate messengers without mixing them with personal ones, and both spaces can work simultaneously in the background.

⚠️ Warning: Deleting the second space will permanently delete all the data stored inside it.Be sure to transfer important files to the main profile or cloud before resetting.

Technically, the implementation takes place at the Android file system level. Each space has its own unique user ID, which allows you to run even those applications that do not support multiple accounts within the application itself. You can log in to the same service (such as WhatsApp or Telegram) from two different numbers at the same time without using third-party cloners.

Differences from Guest Mode and Cloning Applications

Many users confuse three similar features, but they solve fundamentally different tasks: Guest mode is designed to temporarily transfer the device to another person; it does not store data after exit, and does not have its own notification system in the background; Cloning applications (dual applications) allows you to run a second copy of a particular messenger, but all the data is still in the same profile and is visible when you fully access the phone.

In contrast, Second Space is a permanent, full profile, requiring separate setup, login to your Mi Account (optional) and Google account, with its own power saving rules and app permissions, and if Guest Mode is reset when you switch, Second Space keeps its state exactly where you left off.

Let’s look at the function comparison table for clarity:

So if your goal is to hide certain files or apps from children or colleagues while the phone is on the table, you need Second Space, as it provides visual and file masking of the content.

Step-by-step: how to create and configure a profile

The activation process is as simple as possible in modern versions of the shell. You do not need root rights or a connection to the computer. All actions are performed through the standard system settings menu. Before you start, make sure that the device has enough free memory, as creating a new profile will require space for system files.

To start the process, go to Settings, find the Additional (or Advanced Settings) section, and select Second Space. The system will offer a brief description of the features. Press Enable Second Space. The creation process will begin, which can take anywhere from 30 seconds to several minutes depending on the speed of the drive.

Once created, you will be asked to set up your new profile as a new phone: select a language, connect to Wi-Fi and log in to your account. It is important to understand that logging into Google Play in the second space is better done from another account so that contacts and applications are not confused.

Access control and rapid switching techniques

One of the most powerful features is the ability to instantly switch between profiles without fully restarting the device. MIUI and HyperOS have several convenient ways of navigating, the most obvious is through the notification curtain, where the profile switching icon appears, but for increased security and speed, you can use more hidden methods.

You can set up a fingerprint switch. Go to the second space settings and select Add data to unlock. Here you can tie a specific finger: for example, the thumb of the right hand opens the main profile, and the thumb of the left hand immediately switches to the hidden one. This works even with the screen off.

⚠️ Note: If you forget the password or pattern lock from the second space, it will be impossible to restore access to data inside it without resetting.Resetting the password through your Google account may not work due to the isolation of the environment.

A switching method is also available. PIN-When you lock your phone, entering a specific code (other than the main one) will immediately unlock the device in a second space, which allows you to keep the phone unlocked for one set of contacts and applications, hiding the main interface.

💡

Use different wallpapers for the main and second spaces, which will help you visually instantly understand what profile you are in, and not send a personal photo to the work chat.

Data Transfer and Interaction Between Spaces

Although spaces are isolated, the system provides tools for secure data sharing, so you can move files, contacts and app shortcuts from one profile to another, using a built-in import/export mechanism that copies the data rather than moving it around, leaving the original in place.

To transfer a file, open the settings of the second space and select Data Moving. Here you can select the type of content: images, videos, documents or installed applications. The system will create a copy of the selected file in the target profile. Note that some system applications may not be supported for portability.

The same principle works for contacts and messages: you can import contacts from the main profile into the second one so you can access the phone book without mixing up the call history, which is especially useful if you use your phone for work calls in the second space, but you need to quickly find the customer number from the main notebook.

Security issues and concealment of the very existence of the function

For many users, it is critical that no one guesses that there is a hidden profile, and the second space settings have the option to Hide the second space, and when it is activated, the switch icon disappears from the curtain and from the desktop. Access to a hidden profile remains possible only through a pre-configured fingerprint or PIN-lock-screen.

But it’s worth remembering that full cover-up is not absolute protection from professionals: In task manager or battery settings, an experienced user may notice increased resource consumption or strange processes. However, for a household level of protection (from children, friends or colleagues), this level of disguise is quite sufficient.

If you decide to opt out of the function, the deletion is done through the space management menu, the system will alert you to the loss of data and require confirmation, and after deleting all files, applications and settings of the second space will be erased, freeing up space on the drive.

💡

Hiding the switch icon does not remove the second space, but only makes it possible to enter it through biometrics or a special lock pin.
