Smartphones are no longer just a means of communication, becoming digital storage for our lives. Owners of Xiaomi and Redmi devices often face the need to separate work and personal content, but they do not know that the shell MIUI or HyperOS already has a powerful feature built in. The second space is not just a folder hidden by a password, but a full-fledged isolated operating system inside your phone, running parallel to the main one.
Imagine you have two different smartphones in your hands, one with work documents, corporate email and boring apps, and the other with games, personal photos and messengers to chat with friends. That's the ability that this technology brings, allowing you to switch between these worlds with a single finger movement or fingerprint. The unique feature is that it's completely data-isolating: apps in the second space don't see the files of the first, and notifications don't overlap.
In this article, we will take a look at how to activate this mode, what its real security benefits are, and how to set up the switch correctly, how to hide the presence of secret applications from prying eyes and why this tool is necessary for anyone who values their digital privacy.
The essence of technology and the difference from a simple guest mode
Many users confuse Second Space with Guest Mode, which is also present in Android. However, the difference between the two is huge. Guest Mode is a temporary solution that is usually reset after exit, without saving user settings and data. The second space is a full, permanent profile with its own file system, Google accounts and interface settings.
When you create a new profile, the system actually allocates a separate memory partition for it, which means that you can install the same game or social network in both spaces and log in from different accounts. For example, in the main profile you will have a personal WhatsApp, and in the second one – a work number, and both will work simultaneously without the need for constant work. logout/login.
It's worth noting that working in the background in the second profile is also possible, but it consumes the resources of the device. If you run a navigator or file bootloader in the second space, and then switch to the first, the process will continue to run, which makes the feature useful not only for separating life and work, but also for hidden downloads of files or listening to music.
- 🔒 Complete data isolation: files, contacts and browser history are separated at the system level.
- 📱 Cloning Apps: The ability to have two copies of the same app with different accounts.
- ⚙️ Independent settings: different wallpaper, volume, alarm clocks and notification settings for each profile.
Step-by-step instructions: how to activate and configure the mode
It takes only a few minutes to activate the function and doesn't require root rights or complex code manipulations. All the necessary tools are already built into the MIUI and HyperOS shell. First, you need to go to the main settings menu of your device. Usually, the item you're looking for is at the top of the list or in the About section, but the fastest way to use the search.
In the settings search bar, type in "Second Space" or "Second Profile." The system will prompt you to proceed to create. When you click on the activation button, you will see a warning that the function will require additional memory space to work. This is an important point: if your smartphone is crammed to the end, creating a profile may not be possible or not work properly.
☑️ Preparation for profiling
Once confirmed, the system will create a new desktop, and you'll see standard wallpaper and icons, just like on a phone you just bought, and at this point, it's important to set the password and login right away, you can use the same pin as you used to unlock the screen, or you can create a unique one, and the system will suggest you assign a separate fingerprint to instantly log in to the second space.
⚠️ Warning: Don't use the same fingerprints to enter the first and second spaces if you want to maintain a high level of security. If someone unlocks your phone with your finger, they will be placed in the profile that is attached to that fingerprint.
Switching mechanism and access management
The most convenient aspect of using this feature is the speed of switching, so you don't have to enter passwords every time or go through long login procedures. Once you've set up the first one, you can switch between worlds instantly, using a special utility that appears on the desktop of the second space, or a designated fingerprint.
If you've set up the biometrics input, it's magically simple: when you turn off the screen, you put your finger on the right profile, the main finger opens up your personal space, and the "secret" finger (like the left thumb) opens up your work or your hidden finger, which keeps your phone safe even if it's in the wrong hands.
Access control also includes the ability to hide the application icon to switch. You can configure the system so that you only enter the second space by entering a special password on the lock screen or through a double tap on a specific area of the screen, if this feature is supported by your firmware version.
- 👆 Quick switching over the assigned fingerprint on the lock screen.
- 🔢 Entrance through a special PIN-code other than the main.
- 📲 Using a floating window or widget to navigate between profiles.
💡
If you are afraid to forget the password from the second space, link to it Mi Account, which will allow you to restore access through a password reset in case of loss of the code combination.
Hiding applications and files: level of data protection
One of the main reasons users are looking for what 2 spaces in a Xiaomi Redmi phone are is to hide certain apps. Unlike simple “hidden folders” in a gallery, it hides the app itself. To an outsider who took your phone, it will look like Instagram, Telegram or a banking app just aren’t installed on the device.
In the second space settings, you can activate the switching shortcut hiding function, in which case you can only log in through a special password entered on the lock screen, or through a fingerprint, and if an attacker tries to unlock the phone with his primary finger, he will see the clean phone without any hint of the existence of a second profile.
The file system is also split, and the photos taken by the camera in the second space are not displayed in the first profile gallery, the documents uploaded in the hidden profile browser are not visible in the main file manager, which creates a strong barrier to the curious eyes of children, colleagues or in the event of a device loss.
| Parameter | Main space | Second space |
|---|---|---|
| Visibility of applications | You can see all the installed | Only the selected ones are visible. |
| gallery | Personal photos | Hidden/Working photos |
| Notifications | Going to the status bar. | Isolated (not disturbed) |
| Google account | Basic | Separate (no entry required) |

Impact on performance and battery of the smartphone
Using two active profiles inevitably affects the device’s resources. While the current Snapdragon and Helio processors installed in Redmi have enough power, working with two system environments simultaneously increases the consumption of RAM. If your smartphone has only 4 GB of RAM, you may notice more frequent unloading of background applications.
And in terms of autonomy, it depends on your activity, and if the second space is just hanging in the background and doesn't use geolocation or network, the battery consumption will be minimal, but if you have messengers, email clients or widgets, they will consume energy on a par with the main application profile, and double load on the radio module can reduce screen time by 10-15%.
To minimize the impact on performance, it is recommended to disable synchronization and geolocation in the second profile, if they are not needed right now, and it is also worth regularly clearing the cache of applications running in the background of hidden space.
⚠️ Note: When you reset your phone to a factory setting, the data is only deleted from the current active space. To completely clean the phone, you need to reset both profiles separately!
💡
The second space is the balance between convenience and resource consumption. On smartphones with 6 GB of RAM and more, the performance difference is almost invisible, but on budget models with 3-4 GB of RAM, it is better to close unused applications in the second profile.
Frequent problems and ways to solve them
Despite the system's fine-tuning, users may face typical problems: It's common for notifications from the second space to fail or to arrive late, due to aggressive MIUI energy savings, and to fix this, you need to go to the battery settings of the second profile and set the application mode to "No Limits".
Another problem is that you can't delete the second space, and the button can be inactive or hidden, and in such cases, permission checks help: make sure you're in the profile you want to delete, and you can't delete if there's any download or update process going on in the background.
Sometimes users forget the password from the hidden profile. If you haven't linked a Mi Account or asked a control question, it will be extremely difficult to restore access to the data, since the encryption in MIUI is implemented at a high level, in most cases you will have to delete the profile along with all the data.
- 🔋 Check the power saving settings for applications in the second space.
- 📉 Watch for free space: Memory filling can block switching.
- 🔄 Update your system regularly, as Xiaomi often fixes security bugs in this feature.
