The modern smartphone has long ceased to be just a means of communication, turning into a digital safe that stores our personal and professional lives. However, storing banking applications, work chats and personal photos in one pile becomes unsafe and inconvenient. Users are increasingly looking for a way to isolate their work profile from their personal profile without having to buy a second phone. It is for such cases that developers of mobile operating systems have introduced a function second spacethat allows you to create an isolated environment within one device.
This technology works on the sandbox principle: applications installed in the second space do not see the data of the first, and notifications can be completely hidden from prying eyes. The implementation of this function depends on the manufacturer of your gadget: for some it is a built-in system option, for others it is a hidden developer menu, and for others you will have to resort to third-party software. In this article, we will analyze in detail all the available methods so that you can choose the most suitable one for your smartphone model. Android-smartphone.
Before you start setting up, you should understand that creating an additional profile requires certain system resources. RAM and processor will be shared between two active environments, which may slightly affect the autonomy of the device. However, the level of privacy you get in return often outweighs these minimal performance losses.
Native solutions from smartphone manufacturers
Many major vendors have already implemented native support for second spaces directly into their shells on top. Android. This is the most stable and energy-efficient method, since the function is integrated at the system kernel level. For example, device owners Xiaomi and Redmi can take advantage of the “Second Space” function, which creates almost a separate desktop with the ability to set a separate password or fingerprint to log in.
To activate this option on devices MIUI, you need to go to settings and find the appropriate section. Usually the path looks like how Settings → Additional settings → Second space. After pressing the power button, the system will prompt you to configure the unlock method. You can switch between profiles by swiping with two fingers on the lock screen or through a special shortcut in the notification shade.
Users Samsung have an analogue function Secure Folder (Secure Folder), which, although it does not create a full-fledged second desktop, but allows you to isolate selected applications and files in an encrypted container. To activate, go to Settings → Biometrics and security → Protected folder. Inside this container you can install copies of instant messengers, banking applications and a gallery, which will be completely independent from the main ones.
- 📱 Xiaomi/Redmi/Poco: A full second space with a separate set of widgets and wallpapers.
- 🔒 Samsung: Protected Knox folder for isolating specific applications and files.
- 👥 Huawei/Honor: PrivateSpace function, which works similarly to the solution from Xiaomi.
- 🛡️ OnePlus/Oppo: Incognito mode or system application cloner, depending on the version of ColorOS.
⚠️ Attention: On some models of the budget segment, the second space function can be programmatically blocked by the manufacturer to save resources RAM. If you do not find the item in the settings, check the specifications of your model on the official website.
Activation through the menu for developers
If your The smartphone runs on a “clean” Android or shell, where the manufacturer has hidden a convenient power button, you can activate support for multiple users manually. This function is built into the operating system itself, but is often disabled by default in order to simplify the interface for the general user. To access it, you will need to enable developer mode.
First you need to unlock the hidden menu. Go to Settings → About phone and find the item “Build number”. Quickly click on it 7 times in a row until the “You have become a developer” notification appears. After this, a new section will appear in the main settings menu System → For developers. In this menu, you need to find the “Enable multiple users” or “Allow multiple users” switch and activate it.
After enabling this option, a user icon (usually a silhouette of a person) will appear in the notification shade or in the quick access menu. By clicking on it, you can add a new user. This will be a full-fledged second space with its own Google account, settings and applications. Switching between profiles occurs instantly, but applications running in the background of the first profile can be paused to save energy.
☑️ Activating developer mode
It is worth considering that using guest mode or a second user on some custom firmware may limit access to calls and SMS in the second profile. This is done for security purposes so that a second user cannot intercept your messages. Check these restrictions in the access rights settings before transferring important work tools there.
Using third-party clone applications
When system methods are not available or do not suit your tasks, specialized applications from the store come to the rescue. Google Play. These apps create a virtual environment (sandbox) within which the cloned applications run. The most popular solutions are Parallel Space, Island and Shelter.
The application Island, created by the developer of the famous Nova launcher, uses the built-in Android Work Profile. This makes it very lightweight and integrated into the system. After installation Island you will be prompted to set up a work profile, after which copies of your apps with a briefcase icon will appear in the application menu. They work independently, have their own notifications and battery settings.
In contrast, Parallel Space creates its own isolated environment that does not require superuser rights, but consumes more resources, since it emulates the environment within a single process. This allows you to clone even those applications that usually prohibit the launch of multiple copies, for example, some banks or corporate instant messengers.
| Application | Isolation type | RAM consumption | Presence of advertising |
|---|---|---|---|
| Island | System Work Profile | Low | No |
| Parallel Space | Virtual machine | High | Yes |
| Shelter | Work Profile (Open Source) | Low | No |
| 2Accounts | Process cloning | Medium | Yes |
⚠️ Attention: When using third-party cloners, avoid logging into banking applications with critical amounts. The virtual environment may not provide the same level of encryption as the native system space.
Why are some applications not cloned?
Some highly secure banking applications and services (for example, Google Pay or corporate VPNs) may detect running in a third-party sandbox as a security risk and block work. In such cases, only the system second space or developer mode will help.
Configuring notifications and switching
One of the main problems when using two spaces is chaos with notifications. When you have two WhatsApp or two Telegram, it is important to clearly understand where the message came from. In the system settings Android you can flexibly control the display of icons on application icons (badges) and pop-up windows.
To separate information flows, it is recommended to use the “Notification Summary” function or configure different sounds for each profile. If you're using system-based user separation, notifications from the second profile won't appear on the first profile's lock screen by default until you switch. This guarantees complete privacy: no one will see the text of the message from the boss when the phone is on the table unlocked in personal mode.
Quick switching between spaces can be configured through the control panel. Add the Users widget to your notification shade for instant access. On devices Xiaomi the two-finger gesture works on the lock screen, which is the most convenient way to instantly change the context from personal to work.
Set up different wallpapers for the first and second space. This visual anchor will help you instantly understand which profile you are on and avoid accidentally sending a personal photo to your work chat.
It is also important to set up contact synchronization. By default, contacts from different spaces are not mixed. If you need the subscriber's name to be displayed when making a call, regardless of which profile the number is saved in, use the export/import contacts function or synchronize both profiles with one Google account (although this partially negates the meaning of the separation).
Impact on performance and battery
Running a second space is a load on the hardware. Even when you are in the first profile, processes in the second space can consume RAM if there are background services running there. Modern versions Android have learned to aggressively freeze applications in the inactive profile, but it is not possible to completely reset resource consumption.
Expect a decrease in battery life by about 10-15% in the active mode of using both profiles. The processor is forced to handle interrupts and events for two sets of applications. The impact is especially noticeable on devices with 4 GB of RAM or less: the system may unload applications from memory more often, which will lead to them taking longer to load when reopened.
To minimize performance damage, it is recommended:
- 🔋 Disable autorun of heavy applications in the second space.
- 🚫 Do not hold open maps and navigators in the background of an inactive profile.
- ⚙️ Limit background activity for messenger clones if they are not critical.
⚠️ Warning: Interfaces and algorithms for working with memory are constantly updated by manufacturers. The way the system managed the second space in 2023 may differ in new versions Android 14/15. Always check your battery optimization settings after major firmware updates.
Secondary space puts a strain on RAM. If your phone starts to slow down, try closing all applications in the second profile before switching to the main one.
Data security and deleting a profile
The main purpose of creating a second space is security. When using system separation of users, data is encrypted with different keys. Even if an attacker gains physical access to the phone's file system without the password for the second profile, he will not be able to read the data inside it thanks to the encryption mechanism FBE (File Based Encryption).
However, it is worth remembering the risks when using third-party clone applications. They do not provide the same level of isolation as a system profile. The data in Parallel Space is stored in the application's shared folder, which can theoretically be accessed if you have root access or vulnerabilities in the system.
If you decide not to use the second space, it is important to properly delete the profile to free up space and remove all traces. Simply removing application icons is not enough. In Settings, go to Users or Second Space, select a profile and click Delete. The system will warn that all data, including photos, messages and installed apps within this profile, will be permanently deleted.
Settings → System → Multiple users → Select user → DeleteBefore deleting, be sure to back up important data from a second space if it is not synchronized with the cloud. After deleting, the profile will disappear, and the free space on the drive will be available for use in the main mode.
What will happen to the data when resetting the settings?
When you perform a full phone reset (Factory Reset), ALL spaces and profiles are deleted at the same time. The phone will return to the state it was in when purchased, without any trace of the second space.
Frequently asked questions (FAQ)
Is it possible to log into the same WhatsApp account in both spaces?
No, this is technically impossible. WhatsApp messenger is linked to a unique phone number. You can use two different numbers (for example, personal and work SIM cards) to log into two different WhatsApp accounts, but the same number cannot be active in two places at the same time.
Does the owner of the main phone see the browser history from the second space?
When using system separation of users (through Android settings) - no, the history is completely isolated. When using clone applications like Parallel Space, the history is stored inside the application container and is also not visible in the main browser, but is formally located in the shared file system of the device owner.
Is it possible to transfer files between the first and second space?
Yes, but it depends on the method. System solutions (Xiaomi, Huawei) have built-in tools for transferring files between spaces. In the “Multiple Users” mode, sharing is possible through the shared “Downloads” folder or through transfer via Bluetooth/Wi-Fi Direct as between two different devices.
Why did the phone start to heat up after creating the second space?
Probably, synchronization processes, downloading application updates or geolocation work are running in the second space. Check active applications in the second profile and close unnecessary ones. This may also be a consequence of background indexing of files by the system.
Will the second space be deleted when updating Android?
Usually no, system profiles are saved when updating over the air (OTA). However, if you install custom ROM or do a hard reset before updating, all data in the second space will be lost. It is recommended to make a backup before major system updates.
