Owning a modern smartphone often involves dividing digital life into work and personal. Xiaomi device owners, powered by MIUI shells or the new HyperOS, have the unique ability to create a complete, isolated environment directly on a single gadget, a feature known as Second Space that allows two independent sets of apps, contacts, photos and settings to be held, switching between them in seconds.
Many users are wondering how to activate this mode and whether data will be lost when switching. The answer lies in the deep integration of Xiaomi system security tools. The process of logging in and creating a profile is as simplified as possible by developers, but has its own technical nuances that are important to consider for the correct operation of the system.
In this article, we will discuss all aspects of using this feature in detail, where to find hidden settings, how to properly configure fingerprint access, and how this mode differs from a simple guest account, and we will also discuss the issues of performance and security of your personal data.
What is the Second Space and Why is it Necessary?
At its core, this feature creates a virtual copy of the operating system inside your main interface, and it's not just an application folder, it's a fully isolated environment. When you're in the main space, the second one is completely hidden: its applications don't consume battery power in the background, notifications don't come, and geolocation is not tracked.
The main purpose of implementing this technology is to ensure privacy and separate contexts of use, for example, you can install games with aggressive advertising in the second profile so that they do not interfere with the work, or store bank applications and personal photos in a hidden space, access to which is only possible through a special pin code or fingerprint.
⚠️ Note: When you delete the second space, all the data inside it (photos, contacts, installed applications) will be irretrievably destroyed.
System resources are dynamically allocated, which means that if you don't use the second profile right now, it consumes almost no RAM, but the internal storage space will be used for files and cache of applications installed in the hidden profile.
Step-by-step instructions for creating a new profile
The activation process is standard on most modern Xiaomi, Redmi and Poco models. Before you start, make sure that your device has enough free memory, as the system will need space to deploy additional system files.
To start, open the standard Settings app. At the top of the screen is usually the search bar — type in the “Second Space” request there, or find this item under “Advanced Settings” or “About Phone”, depending on the version of your firmware.
☑️ Preparation for activation
After you go to the menu, click the "Enable" button, and the system will suggest you choose how to switch between profiles. You can use a special icon in the notification curtain, a separate password, or, most conveniently, a fingerprint. If you choose biometrics, one finger will open the main profile, and the other (for example, the thumb of the left hand) will immediately start the hidden space.
You then need to set a password to protect, and this password will be used to log into the second space if you choose the method of authorization through the code, rather than through the fingerprint, and once confirmed, the system will create a virtual environment, which can take anywhere from 30 seconds to several minutes depending on the speed of the drive.
Access settings and switching methods
Access flexibility is a key feature of the MIUI shell. Once you create a profile, you can change the way you log in at any time. To do this, go to the second space settings (usually available through the gear icon inside the profile itself or through the phone's main settings menu).
Let’s consider the main methods of authorization:
- 🔑 Password: Classic numerical or graphical code that must be entered at each input.
- 👆 Fingerprint: the fastest way. Assign a specific finger to instantly move out of the blocked state.
- 📱 Switch icon: a special shortcut that appears on the lock screen or in the notification curtain.
Using a fingerprint requires pre-registration of fingerprints in the main profile, and the system will prompt you to attach a finger that will be associated with the second space, which creates a “secret login” effect: for an outsider, the phone will simply unlock into the main profile, and for you it will open hidden data.
What to do if you forget the password from the second space?
Data portability and application installation
Once you've successfully logged in to a new profile, you'll have a virtually clean desktop, no old photos, no contacts, no browser history, and to fill the space with the necessary software, you'll have to go to the GetApps or Google Play app store and install them again.
But it has a convenient import mechanism, so you can move apps, photos, music and contacts from the main space to the second, and you can do that in the second profile settings, you have a special section called Move Data.
It is important to understand the difference between copying and moving:
- 📂 Copy: Creates a duplicate file, and it takes up space in both the main and second profiles.
- ✂️ Moving: The file disappears from the main profile and only appears in the second one, saving space but depriving you of access from the main account.
💡
When transferring large amounts of photos or videos, use a Wi-Fi connection, as the process can consume significant traffic if files are uploaded from the cloud, or simply take up CPU resources.
Some system applications may not be supported for portability, for example, you may not be able to transfer a standard phone or messages in this way, as they are rigidly tied to the mobile phone. SIM-Bank applications may require re-authorization and FaceID settings or a new fingerprint within a new profile.
Comparison with the Guest regime and cloning
Often users confuse Second Space with Guest Mode or App Cloning, which are fundamentally different tools, each of which solves its own problems, and understanding the differences will help you choose the best option for your needs.
Guest mode is designed to temporarily transfer the phone to another person, and it makes no sense to create permanent accounts, because when you leave guest mode, all data is often cleared, while the second space, on the contrary, is created for permanent use by the owner of the device.
The app cloning (or dual apps) feature allows you to run a second instance of a particular messenger (like WhatsApp or Telegram) in the main profile.This is convenient for two SIM cards, but does not provide isolation: notifications come in a common curtain, and access to the files of the cloned application can be seen in the file manager.
| Characteristics | Second space | Cloning of applications | Guest mode |
|---|---|---|---|
| Data isolation | Complete. | Partial | Complete. |
| Data retention | Permanent. | Permanent. | Temporary |
| Notifications | Hidden in the main profile | Come together. | They don't come to the master. |
| Appointment | Personal/Work separation | Two accounts in the same app | Temporary telephone transfer |
Impact on productivity and battery
Using two active profiles inevitably affects device resources. Although the second space is asleep when you're in the main, the system's background processes still serve two sets of settings and services. On modern Snapdragon or Dimensity processors, this is almost invisible.
However, on budget models with 3-4 GB of RAM, you may notice more frequent downloading of applications from memory. If a heavy application is running in the main profile, and a navigator or music player is running in the background in the second, the system can forcefully stop one of the processes to save resources.
And in terms of autonomy, having a second space doesn't waste any power unless you have active processes running there, but if you install applications that have geolocation or a permanent network connection, they will consume power even when you're in the main profile, albeit in a smaller amount.
⚠️ Note: Some antivirus and optimization systems may not properly scan files in the second space, which leads to increased screening time and device heating.
Frequent problems and ways to solve them
Despite the stability of the work, users can face a number of typical problems, one of the most common is the inability to receive notifications from applications installed in the second space while being in the main, this is solved by setting up auto-start and allowing work in the background for specific applications in the battery settings.
Also, there is a “failed to create a second space” error, most often due to a lack of free space or a conflict of system files after updating the firmware, in which case it is recommended to clear the system cache or reset the phone settings (pre-backup).
If the switch icon is missing, check the display settings. In some versions of HyperOS, the shortcut may have been hidden in the corner of the lock screen. Go to the lock screen settings and activate the space switch display.
💡
The second space is a powerful tool for organizing digital detox and sharing work with personal life, but it requires a careful attitude to backing up data.
