The modern rhythm of life dictates its own rules, and often one messenger number is not enough. Separating work and personal accounts is not just a convenience, but a necessity for maintaining a balance between business correspondence and communication with loved ones. Owners of smartphones running an operating system Android 10 are in an advantageous position, since this version of the OS provides ample opportunities for multitasking. However, unlike some newer versions or custom shells, “pure” Android 10 does not always have a built-in button for quickly cloning applications.
Many users mistakenly believe that installing a second copy of the messenger necessarily requires superuser rights or complex manipulations with system files. This misconception may result in loss of warranty or unstable operation of the device. In fact, there are several proven and safe ways to run two WhatsApp at the same time. We will look at methods from built-in manufacturer functions to the use of specialized container applications.
In this manual, we will analyze each step in detail so that you can choose the most suitable option for your smartphone model. It is important to understand that the menu interface may vary slightly depending on the brand of your device, be it Samsung, Xiaomi or Motorola. The main thing is to understand the operating principle of each method in order to competently manage multiple accounts on one device without conflicts and failures in notifications.
Using built-in application cloning functions
The first thing you need to do before looking for third-party solutions is to carefully check the settings of your smartphone. Electronics manufacturers often implement their own tools for duplicating applications, which are more stable than any analogues from the Play Market. This function can be called differently: Dual Apps, App Twin, Clone App or Parallel Apps. The presence of such an option depends solely on the shell manufacturer, and not on the version of Android 10 itself.
To find this function, you will need to go to the system settings section. Usually the path looks like this: go to Settings → Applications → Cloning applications. On Xiaomi i Redmi devices, this function is often placed in a separate “Applications” or “Dual Applications” menu. If you are the owner of a smartphone Samsung, you may need to use the function Secure Folder (Secure Folder), which creates an isolated space for duplicating apps.
If you do not find the cloning function in the standard settings, try use the search inside the settings menu by entering the word “clone” or “dual.”
Activation of the function occurs in one click. After turning on the switch opposite the icon WhatsApp, the system will automatically create a second copy of the application. A new icon will appear on the desktop, often marked with a special icon (for example, an orange or blue corner), which allows you to visually distinguish the primary account from the secondary one. This method is the most preferable, since it does not consume excess RAM and is integrated into the notification system.
☑️ Checking built-in cloning
Use of container applications for cloning
In cases where the smartphone manufacturer has not provided a built-in cloning function, specialized container applications come to the rescue. These apps create a virtual environment inside your phone into which you can install a second copy of any application. The most popular and time-tested solutions are Parallel Space, 2Accounts and Multiple Accounts. They work on the principle of an emulator, running a WhatsApp clone in an isolated space.
The installation process of such a solution is simple: download the selected application from the official store Google Play, launch it and provide the necessary permissions. Inside the container app's interface, you will see a list of installed applications. You need to find WhatsApp and click the add button. After this, the installation process will start inside the container, and you can log in using the second phone number.
⚠️ Attention: Container applications consume more battery and RAM resources than native cloning systems. It is recommended to close the container when the second WhatsApp is not in use to extend the operating time of the smartphone.
One of the key features of using containers is the notification mechanism. To receive messages in the second account, the container application itself must constantly hang in memory or have permission to autorun. In some cases, the Android 10 system can “kill” background processes to save energy, so you will need to add the container application to the list of power saving exceptions.
Why may the second WhatsApp not receive messages?
Often the reason lies in the aggressive energy saving policy of Android 10. The system limits the background activity of applications that you rarely open. To fix this, go to Settings → Applications → Select a container (for example, Parallel Space) → Battery → and select the “No restrictions” or “Do not optimize” mode.
Installing modified versions of the messenger
There is another radical method - using modified versions of a popular messenger, such as WhatsApp Plus, GBWhatsApp or WhatsApp Business. The official WhatsApp Business is available in the Play Market and allows you to legally use a second number on one device in parallel with regular WhatsApp. This is an official solution from the developers, which is completely safe and supports all functions, including business profiles.
Using unofficial assemblies (mods) carries certain risks. Although they offer advanced functionality such as hiding online status, viewing deleted messages, and themes, installing them requires downloading APK files from third-party sources. This violates the terms of use of the service and may lead to temporary or permanent blocking of your number by the administration of the messenger.
If you still decide to use this method, make sure that you download files only from trusted sources to avoid introducing malicious code. Installation is done through the menu Settings → Security → Unknown sources, where you need to allow installation for your browser or file manager. After installing the APK file, you will receive an independent application with its own set of data.
| Application type | Security | Risk of blocking | Availability in Play Market |
|---|---|---|---|
| WhatsApp (Main) | High | No | Yes |
| WhatsApp Business | High | No | Yes |
| Container applications | Average | No | Yes |
| Mods (GBWhatsApp, etc.) | Low | High | No |
Setting up notifications and power consumption
After successfully installing the second instance of the messenger, it is critically important to properly configure the notification system. Android 10 is known for its strict battery management policies, which can prevent messages from arriving in a timely manner to non-essential apps. If notifications arrive with a delay or do not arrive at all, the problem lies precisely in the power saving settings.
You need to find the installed application (or container, if you are using it) in the list of all apps. Go to section Battery or Energy consumption. Here you should select the “No restrictions” operating mode or uncheck the “Save energy in the background” option. This will give the system a signal that this application is a priority and its processes should not be interrupted.
It is also worth checking your notification settings. Make sure that all notification categories are enabled for the second account: messages, calls, and group chats. Sometimes the system may hide notifications from cloned apps by default, deeming them less important. The visual difference between the icons will help you quickly figure out which account received the new message.
The stable operation of the second WhatsApp directly depends on the permissions granted to the application in the “Battery” and “Auto Start” sections.
Solving common installation problems
During the setup process, users may encounter various technical difficulties. One of the most common problems is an error when checking the phone number in the second application. This may happen if the SIM card is not currently active or if the network connection is unstable. Make sure that the SIM card used to register the second account is installed in the phone and accepts SMS or calls for confirmation.
Another common problem is version conflicts. If you try to install a modified version over the official one, or vice versa, the system will throw a package signing error. In this case, you must completely uninstall the previous version of the application, including all its data, before installing the new one. Don't forget to make a backup copy of the correspondence before deleting it, if it is important to you.
Sometimes users complain that the second WhatsApp constantly crashes. This often happens on devices with low RAM (less than 3 GB). In such a situation, using heavy container applications may not be possible. The only way out is to use lightweight versions of applications (for example, WhatsApp Lite, if it is available in your region) or switch to the built-in cloning method, which is better optimized.
⚠️ Attention: Settings interfaces and menu item names may differ depending on your smartphone model and firmware version. If you cannot find a specific setting, check the official documentation of your device manufacturer.
Frequently asked questions (FAQ)
Can you use the same number on two different phones at the same time?
No, the standard WhatsApp protocol does not allow one number to be active on two devices at the same time. When registering a number on a new device, the session on the old phone will automatically end. However, using the Linked Devices feature, you can use your primary phone as a server and a second phone (or tablet) as a client, but your primary phone will still require an occasional connection to the network to function. Is it safe to use apps like Parallel Space? Apps from the official Google Play store are subject to security reviews and are considered relatively safe to use. However, you transfer your account information to a third party developer. For maximum privacy, it is better to use the built-in phone functions or the official WhatsApp Business, which do not require data transfer to third-party container services.

What to do if the second WhatsApp does not receive verification codes?
Make sure the SIM card is active and within network coverage. If the SMS does not arrive, try ordering a voice call to read the code. Also check if your operator has blocked short numbers or Premium SMS services. Sometimes turning airplane mode on and off to reboot the network module helps.
Does the second WhatsApp take up a lot of memory space?
Yes, each application takes up space not only for installing the APK file itself, but also for storing the cache, media files and correspondence database. If you actively use both accounts, the amount of memory used will be added up. It is recommended to regularly clear the cache or use memory cards to store media files, if the smartphone model supports it.
