Transferring a messenger WhatsApp to a new device sometimes becomes an urgent need, especially when there is no access to mobile data or Wi-Fi at hand. Although Google Drive cloud services offer automatic recovery, in some cases the user requires local data transfer via Bluetooth. This is relevant when setting up a smartphone for the first time, while roaming or if there is limited traffic.
It is important to immediately clarify the technical nuance: the application itself is an executable file APK, and your correspondence and media files are stored in a separate database. The standard messenger interface does not have a “Send to a friend” button, so the process is divided into two stages: transferring the installation file and transferring the backup folder. Android allows you to implement this scheme seamlessly if you know the correct algorithm of actions.
Next we will analyze each step in detail, from preparing devices to restoring message history. You will learn how to avoid common mistakes, why sometimes the database is not picked up automatically and what restrictions the protocol imposes Bluetooth on the speed of transferring large amounts of data.
Preparing devices and enabling visibility
The first critical stage is establishing communication between the transmitting and receiving smartphones. Both devices should be in close proximity to each other, preferably at a distance of no more than 3-5 meters, to ensure a stable signal. On both gadgets, you need to activate the wireless module through the quick settings panel or menu Settings → Connected devices.
Particular attention should be paid to the visibility settings. By default, many modern shells MIUI, One UI or OxygenOS hide the device from prying eyes for security purposes. You need to go to the advanced Bluetooth settings and select the "Visible to all devices" option or similar. Without this step, the search for a new device may drag on indefinitely.
⚠️ Attention: When you turn on visibility, your phone becomes available for pairing with any device within range. Once the data transfer is complete, it is strongly recommended that you return your privacy settings to their original state to avoid unauthorized connection attempts.
The pairing process requires confirmation on both screens. When you find the target device name in the list of available devices, the system will ask you to confirm that the digital code matches. Make sure the number combination on both screens is identical before pressing the Pairingbutton. This ensures that you are connecting exactly to the right gadget, and not to the neighboring one.
Exporting the APK installation file
To start using the messenger on a new phone, the installation package itself is required. Unlike transferring contacts or photos, application files are hidden from the standard file manager in system partitions. To access the APKfile, you will need a third-party tool, for example APK Extractor or built-in functions of some shells.
After installing the extraction utility, open it and find it in the application list WhatsApp. Click on the gear icon or menu next to the name and select "Extract" or "Share APK". The system will generate a file that can be transferred. It is important to select the option to send a file, and not a link to the Play Market store.
In the menu that opens for selecting an application to send, find the icon Bluetooth. The system will prompt you to select a previously paired device. Once the sending is confirmed, the receiving device will ask you to receive the file. Agree to the download and wait for the process to complete. The transfer speed will depend on the protocol version and file size, usually it takes from 30 seconds to 2 minutes.
If you have a beta version of WhatsApp or a modified build (for example, GBWhatsApp), make sure that the receiving device allows the installation of applications from unknown sources in the security settings.
Database backup
The most valuable part of your messenger is your correspondence history. It is stored in a local database, which must be manually copied, since automatic synchronization via the cloud is not used in this scenario. To do this, open any file manager on your old device, for example Files by Google or the built-in explorer.
Directory navigation depends on the version of the operating system Android. On older versions (before Android 10), the path looks like /WhatsApp/Databases. On new devices where file access rules have been tightened (Scoped Storage), the path has changed to /Android/media/com.whatsapp/WhatsApp/Databases. Find a file with a name like msgstore.db.crypt14 (the number may differ depending on the encryption version).
Highlight this file with a long press and select the "Share" or "Send" option. In the list of available methods, again specify Bluetooth. Transferring the database may take significantly longer than installing the application, especially if the chats have a lot of media files, which may also be stored in nearby folders. For a complete copy, it is also recommended to transfer the folder Mediaif it is not too large.
| File type | Location (Android 11+) | Location (Android 9 and below) | Importance |
|---|---|---|---|
| Message database | /Android/media/com.whatsapp/WhatsApp/Databases |
/WhatsApp/Databases |
Critical |
| Media files | /Android/media/com.whatsapp/WhatsApp/Media |
/WhatsApp/Media |
High |
| Account settings | Synchronized online | Synchronized online | Automatically |
| Installer | Extracted via utilities | Extracted via utilities | Required |
☑️ Preparing files for transfer
Installing the application on a new phone
After successfully receiving the APKfile on the new device, find it in the folder Bluetooth or Downloads via a file manager. When you try to launch, the system will display a security warning because the file was not downloaded from the official store. You will need to provide permission to install from this source.
Click Settings in the pop-up window and activate the "Allow installation" switch. Go back and complete the installation. After installation do not run application immediately. This is a common mistake: if you open WhatsApp before transferring the database, it will create a new empty database, which can complicate the process of restoring the old one.
⚠️ Attention: Do not log into your account and do not go through the initial setup before copying the backup files to the desired directory. Starting early may overwrite data paths or cause an attempt to download an older version from Google Drive, which will cause an encryption version conflict.
Make sure that the version of the installed app is the same or newer than the one you backed up. If the database file is encrypted with the key from a newer version of the application, the older version of the messenger simply will not be able to decrypt and read it. In this case, you will need to update the application through the official website of the developer.
Moving backup files
Now you need to place the files received through Bluetooth in the correct system directory on the new smartphone. Open your file manager and go to your downloads folder. Find the file msgstore.db.crypt...that you transferred earlier. It needs to be moved (not copied, but moved to avoid confusion) to a folder Databases.
If the target folder is missing, create it manually, following the path structure described in the previous section. For Android 11 and higher, the path will be Internal memory → Android → media → com.whatsapp → WhatsApp → Databases. Make sure that folder names are written accurately and case-sensitive, as the Linux file system underlying Android is sensitive to this.
What to do if the com.whatsapp folder is not is being created?
Sometimes the system does not create hidden folders until the application is launched for the first time. In this case, create a folder structure manually: first the Android folder, inside it media, then com.whatsapp. If the system blocks the creation of a folder in the root of Android, try creating a WhatsApp folder in the root of the internal memory (for older versions of Android) or give the file manager full rights to manage files in the application settings.
After moving, check the file properties. Make sure that its size is not zero bytes and that the modification date matches the backup creation date. If the file is too small (a few kilobytes), the transfer may have been interrupted and the data may be corrupted. In this case, the transfer procedure via Bluetooth will have to be repeated.
Restoring message history
Now you can launch the installed WhatsApp. Go through the registration process by entering your phone number. The system will send an SMS code for confirmation. As soon as you enter the code, the messenger will automatically scan the internal memory for backup copies.
If the files are located correctly, you will see the message “Backup found.” Click the button Restore. Do not click "Skip", otherwise it will be extremely difficult to restore chats without reinstalling the application. The process of unpacking and decrypting the database can take from several minutes to an hour, depending on the amount of history and the processor power of the device.
Once the recovery is complete, click Next. Your chats will appear in the list. Remember that media files (photos, videos) may not be loaded instantly, but as needed or in the background. If you transferred the folder Media separately, make sure that it is also placed in the appropriate directory next to the database.
The success of recovery is 90% dependent on an exact match of the path to the database file and the absence of an attempt to launch the application before transferring the files.
Possible problems and their solutions
Despite its apparent simplicity, transferring data via Bluetooth is associated with a number of technical difficulties. One of the most common problems is the “File not found” error during recovery. This almost always means that the file is in the wrong folder or has the wrong name. Rename the file to standard msgstore.db.crypt14 (or the current encryption version), removing the date from the name.
Another common situation is a 99% transmission interruption. The protocol Bluetooth is sensitive to interference. If this happens, delete the incomplete file from the receiving device before trying again. Do not try to reload it, start the transfer again. Also make sure that the power saving option is disabled on both devices, which may limit the operation of the communication module in the background.
- 📶 Low speed: Make sure that there are no microwave ovens or powerful 2.4 GHz Wi-Fi routers nearby that interfere with the signal.
- 🔋 Disconnection: Check the battery level. When the charge is low, some smartphones artificially reduce the power of the Bluetooth transmitter.
- 📂 Format error: If you are transferring data between phones from different manufacturers (for example, from Samsung to Xiaomi), the folder structure may differ, check the paths manually.
⚠️ Attention: File manager interfaces and system paths may change with Android version updates. If the standard paths do not work, use the file search inside the manager by entering part of the name
msgstoreto find the current location on your specific model.
Why are videos not restored?
Often users transfer only the database file, forgetting about Media folder. The database contains only links to media files and text history. If the folder with pictures and videos is not manually moved to a new directory, "File not found" messages will be displayed in chats or thumbnails will be missing.
Frequently asked questions
Is it possible to transfer WhatsApp via Bluetooth without losing encrypted chats?
Yes, local database contains all messages, including encrypted ones. However, encryption keys are tied to the account and phone number. When restoring on a new device with the same phone number, the application will automatically generate new keys and decrypt the database if the file is not damaged.
How long does it take to transfer a 2 GB database?
Bluetooth speed varies greatly. On version 4.0, the transfer may take more than an hour. On Bluetooth 5.0 and higher, the process will be faster, in about 15-20 minutes. For large amounts of data, this method is considered slow, and if possible it is better to use a cable or Wi-Fi Direct.
What should you do if the application writes “Invalid signature” when installing an APK?
This means that you are trying to install a modified version over the official one or vice versa. Completely uninstall the current version of WhatsApp from your new device before installing the transferred file. Also check if the Google Play Protection feature is enabled, which may block the installation.
Do you need to delete your account on your old phone before transferring it?
No, you do not need to delete your account. WhatsApp allows you to use one number on one active device. As soon as you activate the messenger on the new phone, the session on the old device will automatically end and you will receive a notification about this.
