Second Space on Xiaomi: A Complete Guide to Setup and Use

The second space feature on Xiaomi smartphones is a unique solution for those who want to separate personal and work data, hide sensitive information or simply experiment with settings without risk to the main system.

Many users confuse the second space with guest mode or multiplayer profiles, but it has key differences: you can use the same Xiaomi account (as opposed to guest mode), and synchronize some data between spaces. The feature is available on most devices with MIUI 12 and later, including Redmi models, POCO and Xiaomi’s flagship 13/14 series.

In this article, we will discuss how the second space works, what its limitations are, and how to configure it correctly to avoid common errors, with a focus on security, memory management, and application compatibility.

What is the second space and how it differs from the guest mode

Second Space is an isolated environment within a single device that runs on the same version of MIUI as the main space.

• 🔄 Data Synchronization: You can selectively copy files, contacts, or applications between spaces through the system menu.
• 📱 Same account: Both spaces are tied to the same Xiaomi account, but with different settings and data.
• 🔒 Separate passwords: for each space you can set your own PIN-code, pattern lock or fingerprint.
• 📊 Resource sharing: Memory and performance are dynamically distributed, but some applications (e.g. system services) run in both spaces simultaneously.

Guest mode, in turn, creates a temporary profile without linking to the account, and all data in it is erased after exit, while the second space stores all settings and files until you manually delete it.

⚠️ Note: Some banking applications (e.g. SberBank Online or Tinkoff) may block the second space due to security policies.

How to Enable and Configure Second Space on Xiaomi

The second space will take no more than 5 minutes to activate, but make sure that:

• 📱 It's on the device. MIUI 12 or later (check in Settings) → The phone. → Version. MIUI).
• 🔋 At least 30% battery charge (space creation process requires resources).
• 📶 There is a stable Internet connection (required for downloading system components).

Instructions for setting:

1. Open Settings → Special Opportunities → Second Space
2. Click "Create a Second Space" and confirm the action.
3. Wait until the preparation is completed (the device will restart).
4. After the reboot, select “Second Space” on the lock screen and complete the initial setup (as when you first turn on your smartphone).

Once you have created space, you can switch between them through:

• 🔄 Lock screen (swipe down on profile icon).
• 📱 Notification panel (the icon "Second Space" in quick settings).
• 🔧 Settings (Special Opportunities) → Second space → Switch over).

⚠️ Note: When you first log in to the second space, the system may request re-authorization on Google Play and other services. Use the same data as in the main space if you want to sync in-app purchases.

Memory and productivity management

One of the key limitations of the second space is sharing resources with the main system. By default, MIUI allocates up to 30% of the total memory of the device to the second space, but this value can be changed.

To optimize the work:

1. Go to Settings → Special Options → Second Space → Memory.
2. Select "Set up memory" and specify the desired volume (recommended at least 8-12 GB for comfortable work).
3. Turn on the “Performance Optimization” option if you notice lags when switching between spaces.

Tips for saving memory:

• 🗑️ Delete the app cache in the second space via Settings → Warehouse → Clear the cache.
• 📱 Use lightweight versions of apps (such as Facebook Lite or Messenger Lite).
• 🔄 Turn off automatic app updates in Google Play for second space.

💡

If the second space lacks memory, transfer some files (photos, videos) to the main space through the Settings menu → Second space → File Sharing.

Synchronization of data between spaces

One of the most useful features of the second space is the ability to selectively synchronize data, which allows you to, for example, copy contacts from the main profile to the work profile or transfer photos without using cloud services.

How to synchronize data:

1. Open Settings → Second Space → Data Exchange.
2. Select the data type: Contacts, Messages, Files or Applications.
3. Mark the copy elements and click "Transfer".

Synchronization limitations:

• 🚫 You cannot synchronize passwords, bank application data or settings for some system services (e.g. Mi Pay).
• 🔄 Applications are ported without data (for example, progress in games or settings of messengers will not be saved).
• 📁 Files are only copied to the SecondSpace folder in the internal storage.

Security: How to Protect Data in the Second Space

Although the second space is isolated from the main profile, it is not completely secure from hacking or leakage.

• 🔐 Set different passwords for each space (don’t use the same one) PIN graphical).
• 🛡️ Enable device encryption in Settings → Security → Encryption.
• 🚫 Turn off automatic login to critical applications (banks, instant messengers) in the second space.
• 📡 Do not connect to public Wi-Fi networks in the second space if sensitive data is stored there.

Pay particular attention to SMS-enabled applications (e.g., two-factor authentication) in the second space, they can intercept codes from the main profile if message synchronization is enabled, to avoid:

1. Open Settings → Applications → Permissions → SMS.
2. Disable message access for unnecessary applications in the second space.

💡

The second space does not protect against viruses or spyware. Install antivirus (such as Mi Security) in both spaces and scan the system regularly.

Typical problems and their solutions

When using the second space, users often encounter the following errors:

If the second space stopped starting or if it gives an error "space damaged", try:

1. Reset the device.
2. Remove the second space through Settings → Special Options → Second Space → Delete and Recreate.
3. If the error repeats, reset (Settings → About Phone → Reset), but note that this will delete all data.

⚠️ Note: When you delete the second space, all data in it is permanently erased, including photos, messages and application settings.

Comparison with alternatives: which is better to choose

The second space isn't the only way to divide data into Xiaomi, but let's look at the alternatives and their features.

• 🔄 Guest mode: suitable for temporary access, but not saving data after exit. Useful for demonstration of the device or one-time use.
• 📱 Multi-user profiles (on some models): allow you to create a full-fledged second user with a separate Google account, but require a reboot to change the profile.
• 🔒 Clone applications (e.g. Parallel Space): emulate a second space, but run slower and may conflict with the space. MIUI.
• 🌐 Cloud solutions (e.g. Mi Cloud with multiple accounts): allow data to be shared at the service level, but require a constant internet connection.

Advantages of the second space over alternatives:

• 🔋 Minimal performance impact (unlike cloners).
• 🔒 Native integration with MIUI (There is no risk of conflict with the system).
• 📱 Support for all smartphone functions (including: NFC, camera, sensor).

Disadvantages:

• 📴 Limited memory (cannot be allocated more than 50% of the total volume).
• 🔄 Difficulty synchronizing some data (e.g. passwords or game progress).

💡

If you only need to share messengers or social networks, you’d better use the built-in “Dual Apps” feature in Settings → Apps → Dual Apps. It’s lighter and doesn’t require creating a second space.
