Modern smartphones often become a family gadget or work tool used by different people. However, transferring a device from hand to hand under one account creates risks of data leakage and confusion in applications. The operating system Android provides an elegant solution to this problem - a multi-user mode function. It allows you to create an isolated environment for each person using the device, while maintaining a single hardware base.
The implementation of this feature varies depending on the manufacturer. While on “pure” Android or devices Google Pixel this feature is available by default, some brands, such as Samsung or Xiaomi, may hide it in specific sections of the settings or replace it with analogues like “Operation mode” or “Second space”. Understanding the differences in the interfaces of various shells is critical for successful setup.
In this article we will analyze in detail the process of activating and configuring the second profile. You'll learn how to share personal photos, messages, and apps among family members or colleagues. We will also touch on technical nuances that affect device performance when multiple sessions are running simultaneously, and discuss the limitations imposed by the security system.
Checking compatibility and preparing the device
Before you begin, you need to make sure that your device technically supports the creation of additional profiles. This feature requires sufficient RAM and processing power, since the system must keep multiple user processes running in the background. On budget models with 2-3 GB RAM activating a second user can lead to a significant slowdown in the main interface.
Find the switch in the settings menu. Usually the path looks like this: Settings → System → Multiple users. If you don't see this option, the manufacturer may have disabled it programmatically. Owners of tablets based Android more often encounter full support for the function, while on smartphones it may be limited or absent altogether for ergonomic reasons.
⚠️ Attention: On some devices the function may be hidden in the mode developer or require inclusion via ADB commands. If the standard path does not work, check the specifications of your model on the manufacturer's official website.
Make sure that there is enough free space on the device. Each new profile creates its own file structure, application cache and database. Although the system uses a copy-on-write mechanism to save space, installing heavy games and storing media content in a new profile quickly eats up gigabytes of internal memory.
Step-by-step guide for creating a profile
The process of initializing a new account is intuitive, but requires care when choosing a profile type. The system will offer you two main options: a full-fledged “User” or a limited “Guest”. The choice depends on how long-term and deep the second person’s access to the device should be.
To create a full-fledged account, click the add button in the user menu. The system will ask you to confirm the action, warning that the new owner will be able to install applications and change settings that affect everyone. After confirmation, the initialization process will begin, which takes from 30 seconds to several minutes depending on the speed of the drive.
☑️ Preparing to create a profile
During setup, you will be asked to enter a name for the new profile. This name will be displayed on the lock screen and in the switch menu. It is important to choose a clear name to avoid confusion when changing sessions. You can also customize your avatar at this stage if the manufacturer’s shell supports visual customization of profiles.
After creation is complete, you will find yourself in a “clean” environment. Your contacts, call history, or installed applications will not be shown here. This is an isolated space that functions as a separate virtual smartphone inside a physical device. To access it, you will need to set up an unlock: a pin code, a pattern, or a biometric other than the main one.
Setting up access rights and restrictions
Managing access rights is a key aspect of a multi-user environment. The owner of the main profile (administrator) has full control over the device, including the ability to remove other users and limit their actions. Additional users are not allowed to change global network settings or reset the device to factory settings.
Particular attention should be paid to file sharing. By default, media files can be seen by all users, but system data and documents of each profile are strictly isolated. You can set up public folders to share photos or documents without mixing personal galleries. This is convenient for family use when you need to transfer pictures without using instant messengers.
| Access type | Main user | Additional. user | Guest |
|---|---|---|---|
| Installing applications | Full access | Full access | Temporary access |
| Changing Wi-Fi settings | Yes | Yes (affects everyone) | Yes (reset on exit) |
| Access to contacts | All contacts | Only your own | No access |
| Deleting profiles | Yes | No | No |
Restrictions also apply to calls and SMS. On most smartphones, a second user cannot make calls or send messages through the primary SIM unless explicitly allowed in the settings. This is done to prevent accidental waste of funds or leakage of the administrator's personal correspondence.
Technical details of process isolation
Each user in Android receives his own unique Linux UID (User ID). This means that one user's files have permissions that are physically prohibited from being read by another user at the file system level, even if the device is rooted, without explicit privilege escalation.
Working with apps and data in different profiles
One of the main advantages of separation is the ability to have different sets of apps for different tasks. You can install work instant messengers and email clients in the “Work” profile, and leave social networks and games in your personal profile. Applications installed by one user are not visible to another by default, which eliminates visual noise from the desktop.
However, there is a category of applications that can be accessed by everyone. If an application is installed in the owner's profile and supports multi-user mode, the system may prompt you to install it for all users to save disk space. In this case, application data (cache, logins) still remain separate, but the binary file itself is stored in a single copy.
Data transfer between profiles is carried out not directly, but through shared media resources. If you need to transfer a file, the easiest way is to save it to a folder Downloads or DCIMthat can be scanned by the media server for all users. For more complex sharing, it is better to use cloud storage or the Nearby Share function, which works on top of the separation of profiles.
⚠️ Attention: Deleting an application in one profile does not delete it in another if it was installed independently. If the application was installed “for everyone,” then deleting it by the administrator will delete the app for all users at the same time.
Google accounts are also synchronized independently. In the second profile, you must sign in to your own Google account to use the store Play Market, synchronize contacts and calendars. This ensures that your search results, YouTube recommendations, and location history are not mixed with the device owner's data.
Use the App Clone feature only if multi-user mode is not available. However, remember that cloning only works for selected applications (messengers), while the second user gives complete isolation for any app.
Switching between users and Guest mode
Navigation between accounts is implemented through the quick settings panel or the lock screen. Swiping down from the top edge of the screen opens the notification shade, where the current user's icon is usually located in the right corner. Clicking on it opens a selection menu that allows you to instantly switch to another profile or add a new one.
Guest mode is a simplified version of the second user. It is ideal for situations where you need to give your phone to a stranger to make a call or view a map. The main feature of the guest mode is the ability to completely reset data upon exit. When the guest ends the session, the system offers to delete all files and settings created by him, returning the phone to its original state.
The time for switching the profile depends on the activity of background processes. If another profile is running heavy applications or loading, the transition may take a few seconds. The Android system tries to suspend the processes of an inactive user to save battery, but some services (for example, instant messengers) may continue to run in the background, receiving notifications.
Guest mode automatically clears data after the end of the session, which makes it ideal for temporary access, but unsuitable for permanent use.
Deleting a profile and solving problems
If the need for the second user is no longer necessary, you can easily delete it. To do this, go to the multi-user mode settings, select an unnecessary profile and click the delete button. The system will warn you that all data, applications and settings of this user will be irretrievably lost. Make sure that important information is saved or transferred to the main profile before confirming.
Sometimes users encounter the problem of “ghost” profiles that cannot be deleted using standard means. This can happen after a system crash or a failed update. In such cases, entering safe mode or using the ADB command to forcefully delete a user by his ID helps. The command looks like this:
adb shell pm remove-user Where user_ID is a numeric identifier that can be found through the command adb shell pm list users. Be extremely careful when using this command: deleting the main user (usually ID 0) will result in the device not working and will require a full reset via Recovery.
It is also worth noting the problem with notifications. In some shells, notifications from the secondary user's apps may not appear on the lock screen while the primary profile is active. This is a feature of the security implementation that cannot be changed without deep modification of the system. If it is critical for you to see notifications from both accounts at the same time, consider using two physical devices.
⚠️ Attention: Settings interfaces may differ depending on the Android version and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the described items, check the official documentation for your specific phone model.
Frequently asked questions (FAQ)
Is it possible to receive calls on a second profile?
By default, the second user does not have access to phone functions (calls/SMS) through the main profile SIM card. However, on some dual SIM devices you can configure call routing, but this depends on the specific model and firmware version. Most often, the second profile is used only for working with data and applications.
Does the second user take up a lot of disk space?
The empty profile itself takes up minimal space (several megabytes of system files). Most of the memory is consumed when installing applications and saving photos. Applications installed “for everyone” take up space only once, but their data (cache) is duplicated for each user.
Will the battery drain faster with two users?
Yes, the background activity of the processes of the second user (mail synchronization, instant messengers) leads to increased battery consumption. The Android system tries to optimize this process by freezing inactive profiles, but it is not always possible to completely stop background services, especially if the profile runs navigators or streaming services.
Is it possible to restore a deleted profile?
No, deleting a profile is
