Moving to a new device or the need to simultaneously use the messenger on two smartphones is a common situation faced by millions of users. The process of how to log into your WhatsApp on another Android phone depends on your ultimate goal: whether you want to completely transfer your correspondence history to a new gadget or plan to use the second phone as an additional terminal for reading messages. In the first case, we are talking about data migration with reference to a number, in the second - about the “Linked Devices” function, which allows you to bypass the limitation on one active smartphone.
Modern ecosystem Meta offers flexible tools for account management, but many users are still confused in the backup and recovery procedures. Incorrect actions may result in the loss of important photos, voice messages or documents. Therefore, it is critical to understand the differences between a regular login with backup recovery and multi-device mode before you begin setup.
Preparing your old device for data transfer
Before you try to activate your account on a new smartphone, you need to make sure that all the data on your old device is saved in cloud storage. This is a fundamental stage, without which restoration of correspondence is impossible. Go to the application settings and find the section Chats → Chats backup. Here you will see the date of the last save and the amount of space occupied.
Make sure that the backup is configured to use Google Drive, and not just the phone's internal memory. Local copies are often lost when there is a factory reset or the drive is damaged. Select the frequency of creating backups, for example, “Daily,” to minimize the risk of losing recent messages. Also check if your Google account is connected in the phone's system settings, as the application will not be able to download the file without authorization.
If you have limited traffic or a slow connection, it is recommended to connect the device to the network Wi-Fi before starting a forced backup update. Press the button Backup and wait for the process to complete. This action will create a fresh snapshot of all your conversations in the cloud.
⚠️ Attention: The backup copy is tied to a specific phone number and Google account. You will not be able to restore chats from +7900... to a Google account registered in the name of another person without access to their mail.
☑️ Preparing for transfer
Classic login with full history restoration
This method is suitable for those who change their phone and want to see the entire correspondence history on the new device, In this case, the old phone will stop receiving messages. Installing the application WhatsApp on a new smartphone begins with the standard download procedure from the store Google Play. Once launched, you will be asked to accept the terms of service and enter your phone number.
Enter the same number you used on your old device. The system will send SMS code or offer automatic entry through the confirmation service. After successful verification, the application will detect the presence of a backup copy on the linked Google account. A request to restore chats and media files will appear on the screen.
It is critically important to press the button Recover at this stage. If you accidentally click "Skip", the application will launch in its pure form, and it will be extremely difficult to get back old messages without reinstalling. The process may take from several minutes to an hour depending on the amount of data and Internet speed.
| Process stage | User action | Risk of error |
|---|---|---|
| Installation | Downloading from Google Play | Downloading modified versions (unsafe) |
| Verification | Entering a number and SMS code | Entering a code on an old phone (will leave the network) |
| Recovery | Clicking the "Restore" button | Clicking "Skip" (loss of history) |
| Setting up a profile | Entering a name and photo | No significant risks |
If the recovery is stuck at 99%, do not reboot the phone right away. Wait 10-15 minutes, sometimes the system indexes media files in the background.
Using the “Linked devices” mode
Modern versions of the messenger allow you to log into your account on a second Android phone without disconnecting the main one. This feature is called “Linked Devices” and turns the second smartphone into a full-fledged client that synchronizes messages in real time. This is an ideal option for those who want to separate their work and personal phones, but receive notifications on both.
To implement this scenario on a second (new) phone, do not enter the phone number when starting the application. Instead, click on the three dots in the upper right corner of the screen and select Connect as an additional device. A QR codewill appear on the screen, which needs to be scanned.
Take your main phone, where the account is already active. Go to menu Settings → Associated devices → Device connection. Allow access to the camera and point the lens at the QR code displayed on the screen of the second phone. After successful scanning, the correspondence history will begin to synchronize.
⚠️ Attention: The main phone must be connected to the Internet at least once every 14 days, otherwise additional devices will be automatically disabled for security reasons.
How many devices can connect?
You can connect up to 4 additional devices at the same time. These could be other smartphones, tablets or computers. All of them work independently of the main phone, even if it is turned off, but synchronizing new chats requires the main account to be online periodically.
Login through emulation or application cloning
Some smartphone manufacturers, such as Xiaomi, Samsung or Huaweioffer a built-in cloning function applications. This allows you to install a second WhatsApp icon on the same phone or use specific settings to log in with a different number without third-party software. However, if we are talking about logging into same account on different phones without the linked devices mode, restrictions arise here.
An attempt to simply install the application and enter the same number on another device will result in the session on the first phone being forcibly terminated. The messenger does not support simultaneous activation of one number in the “main device” mode on two different phones. The only exceptions are corporate solutions or specific modifications, which are not recommended for use due to the risk of blocking.
If your goal is to have two different accounts on one Android phone, use the function Cloning applications in the system settings. To log into your WhatsApp on another phone with the same number, the only correct legal way is the method through the QR code described in the previous section.
- 📱 Built-in clones work more stable than third-party apps.
- 🔒 Using unofficial clients (GBWhatsApp etc.) threatens to permanently block the number.
- 🔄 The linked devices mode allows you to read the history even when the main phone is turned off (up to 2 weeks).
Restoring from a local backup
Sometimes Google Drive cloud storage is inaccessible, damaged, or the user fundamentally does not want to use it. In such cases, you can use a local backup, which is stored in the phone memory or on the SD card. The files have names of the form msgstore-2023-10-25.1.db.crypt14, where the numbers indicate the date, and crypt14 is the encryption version.
To recover data using this method, you will need a file manager. Find the folder Android/media/com.whatsapp/WhatsApp/Databases (on new versions of Android) or just WhatsApp/Databases (on old ones). Copy the desired backup file to the new phone in the exact same directory. Rename the file to msgstore.db.crypt14 (removing the date from the name), but leave the encryption version extension unchanged.
After moving the file, install the application on the new phone. When checking the number, the system will not find a copy in Google Drive, but will detect a local file and offer to restore chats from it. This method requires careful attention to the encryption versions: if you try to restore a copy of crypt12 when you have installed a version of the application that only supports crypt14, the restoration will fail.
Local recovery is an “emergency” method. It is more complicated than the cloud version, but is indispensable if you do not have access to the Internet or a Google account at the time of moving.
Typical problems and ways to solve them
Despite its apparent simplicity, users often encounter errors when logging in. One of the most common is the message “The backup could not be restored.” This is often due to mismatched Google accounts. Make sure that in your phone settings you have added exactly the mailbox to which the backup was made.
Another common problem is endless downloading of media files after logging in. This is normal behavior when there is a large amount of history. Do not uninstall the application in this case. Leave your phone connected to charger and Wi-Fi overnight. The process of loading photos and videos in the background can take considerable time.
If you use two-factor authentication (PIN), be prepared to enter it when logging in on a new device. If you forget this code, access to your account will be blocked for 7 days. The support service cannot reset this code instantly, since it serves as the main protection against hacking.
⚠️ Attention: The interface and paths to settings may vary slightly depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the menu item, use the search inside the phone settings.
Frequently asked questions (FAQ)
Is it possible to log into WhatsApp on two phones at the same time with one number without a QR code?
No, the standard messenger protocol prohibits the activation of one number as the “main device” on two different phones at the same time. Trying to log in via SMS on a second phone will automatically log you out of the first one. The only way to work on two devices is to use the “Linked devices” mode by scanning a QR code.
What happens to my chats on the old phone after logging in on the new one?
If you performed a full transfer with restoration from a backup, the old data will remain on the old phone, but new messages will not arrive there - they will only arrive on the new phone. If you used the “Linked Devices” mode, then the correspondence will be synchronized on both devices in real time.
How to transfer WhatsApp from Android to iPhone or vice versa?
Direct transfer via Google Drive or iCloud cloud is not possible due to differences in systems. Switching from Android to iOS requires a cable connection and the Transfer to iOS utility when you initially set up your iPhone. In the opposite direction (from iOS to Android), the function is available on Samsung smartphones and some other models during initial setup or through special cables.
Is it safe to use clone apps to log into WhatsApp?
Using the official application cloning function built into the phone (for example, Dual Messenger) is safe. However, installing third-party modified versions of the messenger (so-called “gray” assemblies) carries a high risk. WhatsApp developers are actively blocking numbers that use unofficial software, and there is also a threat of personal data leakage.
