Second Space in Xiaomi: What It Is, How to Set Up and Why You Need to

If you own a Xiaomi, Redmi or a smartphone POCO, You've probably encountered the mysterious "Second Space" feature in your settings. MIUI Since version 8, many users still don't understand what it's about, and we'll look at what's behind it, how it works in practice, and who's really going to use it.

The second space is not just an extra account or a guest mode, but essentially a fully-fledged, isolated copy of the operating system on one device, with its own apps, settings and data, Think of it as two independent smartphones in one enclosure, a feature that is particularly relevant for those who want to delineate their personal and work environments, test apps without risking the underlying system, or hide sensitive information from outsiders.

In this article, we will go into detail all aspects of the second space, from basic settings to hidden features that are not mentioned in the official instructions, learn how to correctly switch between spaces, what data is synchronized between them, and why some users mistakenly confuse this feature with multiplayer mode in Android.

What is the second space in Xiaomi and how does it work?

Second Space is a unique development of Xiaomi, which allows you to create an isolated virtual environment on your smartphone with a separate desktop, applications and settings. Unlike the standard guest mode in Android, this is a full-fledged second operating system that runs parallel to the main one.

Technically, the function is implemented through a Multi-ROM mechanism, where each space has:

• 📱 Own launcher with a unique set of icons and widgets
• 🔑 Individual accounts (including Google, Mi Account and social media)
• 📁 Isolated storage (files from one space are not visible in another)
• ⚙️ Independent system settings (sound, network, permissions, etc.)

It’s important to understand that the second space is not the same as the multiplayer mode on pure Android.The latter usually limits functionality (e.g., blocks calls or blocks calls). SMS), Second Space, in the same way. MIUI It provides full access to all smartphone functions, including:

• ☎️ Calls and messages (with a common number but a separate history)
• 📶 Mobile Internet and Wi-Fi (network settings do not overlap)
• 🔋 Battery and performance (each space consumes resources independently)

One of the key benefits is security, because if a smartphone is infected in the main space, the other one will remain intact, which is true for users who often install applications from unverified sources or work with sensitive data.

Differences between the second space and the guest mode and the multiplayer profile

Many people confuse the second space with other access differentiation features in Android, and let’s look at the key differences in the table:

The critical point is that the second space in Xiaomi uses a common file system, but with different access rights, which means that the physical data is stored on the same drive, but logically separated. For example, if you download a file in the main space, it will not be visible in the second one, and vice versa. However, both spaces consume space from the total memory of the smartphone.

Another important difference is autonomy: the second space can work even if the main one is locked with a password or a fingerprint, which is useful if you want to give a smartphone to a child or a colleague without disclosing personal data, while in guest mode, many functions (such as access to a gallery or contacts) can be blocked by the administrator.

💡

If you need to temporarily hide personal data, but do not want to configure the second space, use the Private Mode function in the Internet. MIUI. It hides selected files and applications behind a password without creating a separate environment.

How to Enable and Configure Second Space on Xiaomi

Activating the second space takes a few minutes, but requires attention to detail. MIUI 12/13/14 (including Redmi, POCO and Black Shark):

1. Open Settings → Special Opportunities → Second Space
2. Click on “Create a Second Space” and confirm the action.
3. Enter your login password (required! This will protect the data from accidental access).
4. Select which data to copy from the main space (contacts, messages, applications – optionally).
5. Wait until the setup is complete (it can take 5-10 minutes depending on the model).

Once you have created the second space, you can switch between the two:

• 🔄 Through the notification curtain (the icon "Two people»)
• 🔑 Through the lock screen (swipe up/down) + space-selection)
• ⚙️ Through Settings. → Special facilities

Note that when you first start the second space, the system will suggest you set it up as a new smartphone (Google account input, topics selection, etc.) this process can be skipped, but then some features (such as Google Play) will not be available.

⚠️ Note: If you delete the second space through the settings, all the data inside it (photos, messages, accounts) will be permanently erased!

Hidden Second Space Opportunities: What a Function Can Do, What It Doesn't Write About in the Instructions

1. Different versions of applications in the same smartphone

You can install different versions of one app in each space, like the main space, where you have a stable version of Telegram, and the second space, a beta version for testing, and that works because the spaces have separate package managers.

2. Circumvention of regional restrictions

If you have a Mi Account set up in the main space with Russia, in the second space you can create an account with Europe or China.
