Second space on Xiaomi Redmi: a complete setup guide

Modern smartphones have long ceased to be just devices for calls, turning into universal digital storage, where personal life, work projects and entertainment content intertwine. Owners of Xiaomi Redmi devices often face the need to strictly separate these areas, so as not to mix work chats with personal photos or game accounts with banking applications. MIUI (The new HyperOS feature was introduced under the name “Second Space».

This technology allows you to create a virtually independent second operating system inside your smartphone with its own set of applications, contacts, gallery and settings. You can switch between the main profile and the second space with a single touch or a special fingerprint, which creates the feeling of using two different phones in the same case. Understanding what the second space on Xiaomi redmi means opens up the possibility for the user to improve productivity and increase data privacy without having to buy an additional device.

Unlike just hiding apps or using guest mode, the second space provides complete data isolation, so if you hand over your phone to a colleague or child in the primary mode, they won't be able to physically access the files and programs installed in the second profile unless they know the password or use your biometric key, which makes it indispensable for those who value their digital hygiene and want to keep information structured.

The essence of technology and the principle of insulation

Technically, the second space is a separate user profile in the Android operating system, which is completely isolated from the main one. When you create a new profile, the system allocates a separate partition for it in memory, where all the data is stored: app cache, messenger databases, photos and system settings. This means that logging into a Google account in the second space does not affect the main account, which allows you to use two different phone numbers or email addresses at the same time.

Many users mistakenly believe that the second space is just a folder with a password, but it is a much deeper integration. When switching between profiles, the smartphone interface is completely updated: wallpaper, widget location, list of installed programs and even volume or brightness settings. Data isolation works at the file system level, so no application from the main profile can “see” or scan files from the second profile without special permission and access through the system Explorer, which is also divided.

⚠️ Note: Creating a second space takes up an additional amount of internal memory. If your Redmi has less than 5 GB of free space, the system can warn you that you can not create a profile or work slower.

It is important to note that some system resources, such as a communications module or GPS, are shared, but their use is controlled separately for each profile. For example, you can turn off geolocation in the second space while it is active in the first.This gives flexibility in managing power consumption and privacy, allowing you to fine-tune the behavior of the smartphone in different use cases.

Main use cases of the function

Xiaomi’s second space isn’t limited to just one scenario, although it’s often used to separate work and leisure, but the customization features allow you to adapt this feature to a variety of needs, making your smartphone a universal tool.

One of the most popular scenarios is to create a clean desktop, where you can install only the apps you need to work with: corporate email, messengers to connect with colleagues, and task managers, and by including this profile during work hours, you eliminate distractions like notifications from Instagram or TikTok that remain in the main profile, which helps you keep your focus and improve productivity.

Another popular use case is to create a safe environment for children or guests, and you can set up a second profile with a limited set of apps (like YouTube Kids and tutorial games only), set parental controls, and not worry that your child will accidentally delete important files or stumble upon unwanted content in the primary browser, and it’s also convenient when handing the phone over to a navigator in a car or a colleague to show you a presentation.

• 🎮 Game Profile: A separate gaming space allows you to disable call and message notifications so that nothing interrupts the gameplay, as well as use different accounts in games.
• 💼 Incognito mode: To store confidential documents, photos or correspondence, access to which is extremely rare and only by fingerprint.
• 📱 Application Testing: Developers and advanced users can install questionable or test versions of programs (APK) in the second space without risking the stability of the main system.

Another interesting case is using different interface languages or regions, and in the second space, you can set a different language, which is useful for learning foreign languages or for people who share a phone with relatives who do not speak the primary interface language, all settings, including keyboard layout and voice input, will be independent.

Step-by-step instructions for creating and configuring

The process of activating the second space on Redmi smartphones is as simple as possible and takes only a few minutes. However, it is important to correctly perform the initial settings so that you do not later encounter any inconvenience when switching or lack of memory. Before you start, make sure that your device is updated to the current version of MIUI or HyperOS.

To start the process, go to the settings menu. Find Settings → Second Space (some firmware versions may have Additional Settings → Second Space). Click on “Enable Second Space.” The system will warn you that the function will require additional space and prompt you to create a profile.

Once confirmed, the system will create a new profile, and you will be in an interface that looks like a new phone that has just been turned on, where you will need to re-select the language, connect Wi-Fi, and, if you wish, log into your Google account (or create a new one). At this point, it's important to configure the unlock method. You can set a separate pattern lock, PIN-code or attach a second fingerprint for instant entry.

Special attention should be paid to setting up a quick switch, in the notification curtain of the second space will appear a special icon that allows you to return to the main profile, also in the settings you can activate a floating button for a quick transition. If you want the second space to be completely hidden, do not add a switching shortcut to the main desktop profile and use only biometrics or codes.

⚠️ Note: When setting up the second space, the system may suggest migrating some applications from the main profile. Do this only with proven programs, as their data will be copied, but further synchronization between profiles will not work.

Access control and switching techniques

One of the key features of Xiaomi’s second space is the flexibility of access control, so you can switch between profiles in a number of ways, choosing the most convenient one for your situation, the standard method is through the “Second Space” app in the main menu or through the notification curtain, where the corresponding toggle switch is displayed.

However, the most effective and safe way is to use biometric unlocking, so in the second space settings (Settings → Second Space → Unlocking Setup), you can assign a separate fingerprint, which means that by putting a finger registered for the second profile, the phone will immediately unlock and enter it, bypassing the main screen, which creates a “hidden” mode effect.

For those who prefer graphic keys, there is a quick code switching feature available. You can configure that you enter a certain type of code. PIN-The lock screen immediately opens the second space, while the main code opens the main profile. This is ideal if you can be asked to unlock the phone and you want to quickly show the "safe" interface.

💡

Use different wallpapers for each space, and not only does it help you visually navigate which profile you are in, it also prevents you from accidentally sending files to the wrong messenger account.

It is important to remember that you can remove the sign-in label. If you hide the Second Space icon from the main menu, you can only access it through settings (Settings → Passwords & Security → Second Space) or with a designated fingerprint/code, which adds an additional level of privacy, as the unauthorized person who took your unlocked phone may not know that a hidden profile exists.

Data transfer and interaction between profiles

Despite its strict isolation, MIUI provides convenient tools for transferring files between the main and second spaces, when you need to quickly transfer a photo, document or contact information from one profile to another, the process of moving data is completely controlled by the user and does not happen automatically.

To move files (photos, videos, documents) you use the built-in import/export function. When you're in the second space, go to Settings → Second Space → Move Files. Here you'll see two tabs: "From Second Space" and "To Second Space." When you select files, you copy them to the corresponding folder of another profile. After copying, the original in the original profile is saved unless you manually delete it.

Contacts are the same thing. You can export contacts from the main profile to the second one and vice versa. This is convenient if you need to call someone from the second account, but the number is saved in the main phone book, the system will suggest you to select specific contacts or copy everything at once, which takes seconds.

• 📷 Gallery: Photos can be moved in a package by selecting entire albums or shooting dates.
• 📞 Contacts: When copying contacts, the system will warn about duplicates, suggesting that records be combined or new ones be created.
• 📄 Files: All file types are supported, including archives and office format documents.

Note that apps don’t flow automatically between spaces. If you need WhatsApp or Telegram in your second profile, you’ll have to download it and reconfigure it. However, the history of correspondence is not automatically transferred when you install it, so use the backup function inside the messengers themselves before you move to the new space to save important dialogs.

Impact on productivity and battery

The use of the second space imposes certain requirements on the hardware resources of the smartphone. Since the device actually runs two independent environments, the consumption of RAM (RAM) increases. Even if you do not use the second space actively, the system processes there can continue to work in the background, receiving notifications and updating data.

This can lead to faster battery drain, especially if the second profile has "heavy" active-synchronization applications installed, such as email clients or navigators. background activity in the second space consumes energy as much as it does in the main.So if you're not using the second profile right now, it's recommended to completely close the apps inside it or temporarily turn off sync.

On devices with a small amount of RAM (4 GB or less), active use of second space can lead to more frequent downloading of applications from memory.This means that when switching between profiles, applications can restart (“blink” the saver), which creates a sense of slowing down the smartphone. On the flagship models of Redmi with 8 GB of RAM and more, this effect is almost invisible.

⚠️ Warning: The second space is not a military-standard encryption tool, and while access is password-protected, a technically savvy attacker with physical access to the device and specialized software can extract data. Do not store critical information in the second space if the device could fall into the wrong hands.

Removal and resetting of second space

If you don't need a second profile, or if you've optimised your smartphone to free up memory, it can be easily deleted, and it's important to understand that removing the second space will result in the complete and permanent removal of all the data, applications and settings inside it, while leaving the main profile completely intact.

To delete, go to Settings → Second Space. In the upper right corner, click on the menu icon (three dots) and select “Delete Second Space.” The system will ask you to confirm the action by warning you of loss of data. Once you enter the unlock password, the process will take a few seconds, and the phone will return to state with one active profile.

If you forget the password from the second space and can't log in, the only way to access it is to completely reset your smartphone to factory settings, which will delete data from both profiles, so it's crucial to remember your password or use biometric unlock, which always works while the phone is on.

💡

The second space is a powerful tool for sharing digital life, but it requires careful management of memory and passwords, as data recovery after deleting a profile is impossible.
