Loss of important correspondence in messenger is a situation that every smartphone owner has encountered at least once. On devices Samsung managed Android the data return process has its own nuances associated with the features of the file system and the application algorithms. Fortunately, the architecture WhatsApp provides for several levels of information protection, which gives the user a real chance to recover lost dialogs.
The message history saving mechanism works in the background, creating copies of data in the cloud storage and in the internal memory of the device. However, the success of the operation directly depends on exactly when the last backup was created and whether it was overwritten after the chat was deleted. In this article we will analyze in detail all available methods, from standard procedures to working with system files.
Before taking active steps, you need to assess the scale of the problem and understand what type of backup was activated on your Samsung Galaxy. Ignoring this stage may lead to the fact that you will completely lose the opportunity to restore data by replacing the old copy with a new one, without the necessary messages.
The mechanism of backup copies in WhatsApp
Understanding how exactly the messenger saves data is the key to successful recovery. The application uses two main channels for backup: cloud service Google Drive and local storage in the phone memory. Cloud backup is convenient because the data is tied to the account and is available when changing the device, but it has a critical time delay.
Local copies are created automatically every night at 02:00 and stored in the internal memory or on a memory card microSD. These files have the extension .crypt14 or .crypt15 depending on the application version and contain encrypted correspondence history for the last 7 days. It is working with local files that often allows you to return messages that have not yet been synchronized with the cloud or were deleted after the last cloud synchronization.
⚠️ Attention: Encryption of backup copies is one-way. You cannot simply open the backup file and read the text without the recovery process through the official WhatsApp application.
It is important to consider that when restoring from the cloud Google Drive you roll back the state of the chats exactly at the time this copy was created. All messages received after this time will be permanently lost unless they were saved in another way. Therefore, before starting the procedure, always check the date and time of the last saved backup in the application settings.
Before restoring, check the date of the last backup in the WhatsApp menu -> Settings -> Chats -> Chat backup. This will help you understand which messages you will lose during a rollback.
Restoring from a cloud copy of Google Drive
This is the simplest and most common method that suits most users who regularly synchronize data. To implement it, you will need the same account Googlethat was used to create the backup, and a stable network connection Wi-Fi. The process is fully automated and does not require intervention in the file system.
The algorithm of actions is extremely simple: you need to delete the application WhatsApp from your smartphone Samsung and install it again from the store Google Play. When you first start and enter your phone number, the system will automatically detect an available backup copy in the cloud and offer to restore it. Refusal of this offer at this stage will lead to the fact that it will be impossible to restore data using the standard method later.
- 📱 Delete the current version of WhatsApp through Settings -> Applications.
- ☁️ Make sure that the same Google account is active on your phone as when creating the backup.
- ⬇️ Download the messenger again and go through the number verification procedure.
- 💾 Click the "Restore" button when the corresponding request appears.
The speed of the process depends on the size of the archive and the speed of the Internet connection. During loading, the progress bar may freeze at a certain percentage - this is normal when unpacking large databases of media files. Do not interrupt the process or lock the device screen to avoid damaging the restored database file.
Restoring from a local backup
If the cloud backup is out of date or missing, local copies stored in the device memory come to the rescue Samsung. This method requires more careful handling of files, since you will have to manually replace the current database with the saved version. First you need to find the folder with backup copies, which is usually located along the path /sdcard/WhatsApp/Databases or /sdcard/Android/media/com.whatsapp/WhatsApp/Databases on new versions Android.
In this directory you will find a file msgstore.db.cryptXX (current database) and files with names like msgstore-YYYY-MM-DD.1.db.cryptXX (archive copies for past days). To restore correspondence for a specific date, you need to rename the current file, adding any ending to it, for example .old, and rename the selected archive file to msgstore.db.cryptXX, removing the date from the name.
Was: msgstore-2023-10-25.1.db.crypt14
Became: msgstore.db.crypt14
After renaming the files, you need to clear the application data WhatsApp in the phone settings or reinstall it. When launched, the messenger will detect a local file with the name msgstore.db.cryptXX and offer to restore the history from it, ignoring the cloud copy at this moment if you turn off the Internet before starting the application.
☑️ Preparing for local recovery
⚠️ Attention: On Samsung smartphones with One UI shell, access to the Android folder can be limited. Use the built-in file manager "My Files" or connect your phone to a PC for convenient work with directories.
Using third-party software and file managers
To manage backup files on Samsung an advanced file manager is often required, since standard tools may hide some system directories or not allow rename files with certain extensions. Applications like Solid Explorer or FX File Explorer provide full access to the file system and allow you to work with encrypted databases more flexibly.
Some users resort to using specialized PC software that promises to recover data directly from the phone’s memory without backups. The effectiveness of such utilities, such as Dr.Fone or Tenorshare UltDatavaries greatly and depends on the phone model and version. Android. In most cases, they scan only those data that have not been overwritten by new memory cells.
| Recovery method | Required backup | Complexity | Risk of losing new data |
|---|---|---|---|
| Google Drive | Cloud | Low | High (from the moment of backup) |
| Local file | Internal memory | Average | Average (depends on the file date) |
| Third-party software | Not required (search for deleted files) | High | Low (but low guarantee of success) |
When using third-party apps, it is important to remember the security of your personal data. Giving full access to your phone to unverified software can lead to leakage of confidential information. Always download such utilities only from official developer sites and avoid dubious free versions.
Why are not all files restored?
The flash memory of smartphones is designed in such a way that when a file is deleted, the space it occupied is marked as free. New data can be written over deleted messages, making their recovery impossible even for special software.
Recovery of individual messages without rollback
Often, users do not need to return the entire correspondence history, but only one specific message or media file that was deleted by mistake. Unfortunately, using standard means WhatsApp it is impossible to unload a single message from a backup copy - the process always involves completely replacing the current database with an archived one. However, there are workarounds for media files.
If we are talking about photos or videos, it is worth checking the folder .Statuses or gallery of the device, since media files are often duplicated in different directories. You can also ask the other person to export the chat. The "Chat Export" function allows you to send your chat history as a text file .txt along with attachments to email or another messenger.
To export, go to the contact or group information, scroll down and select Exporting a chat. You will be able to choose whether to attach media files to the archive. The resulting file can be opened on any device and read the history, although it will not be possible to return these messages back to the application interface in this way - they will remain in the form of an archive for reading.
Exporting a chat is a one-way process. You receive a file to read, but you cannot import it back into WhatsApp to continue the conversation in the same window.
Typical errors and ways to prevent them
One of the most common reasons for recovery failure is a conflict in encryption versions. If you try to restore a copy created on a newer version WhatsAppto a device with an older version of the application, the process will fail. Always update the messenger to the latest current version before you start manipulating databases.
Another common problem is lack of memory space. To unpack a backup copy Google Drive or a local file, an amount of free space is required that is 2-3 times larger than the size of the archive itself. If the phone memory Samsung is full, the system will not be able to correctly deploy the database, and you will receive an error message during the installation process.
⚠️ Attention: Menu interfaces and file paths may vary slightly depending on the version of the One UI shell and the version of Android. Always check the current settings of your device.
It is also worth mentioning the problem with the phone number. Backups are linked not only to your Google account, but also to your phone number. If you have changed your SIM card and number, you will not be able to restore old correspondence to a new number using the standard method unless you have first completed the number change procedure within the application itself before deleting your account.
Free up at least 5-10 GB of free space before restoring a large database. This will prevent failures when unpacking media files and ensure the integrity of the restored correspondence.
Is it possible to restore messages if I did not make backup copies?
The chances are extremely low. Without a local or cloud backup, correspondence can only be restored using specialized paid PC software that scans the phone’s memory. However, success is not guaranteed, especially if the phone was actively used after deleting messages.
What to do if WhatsApp writes “File is damaged” when restoring?
This means that the backup file was not downloaded completely or was damaged during storage. Try choosing a different date for the local backup (files are stored for 7 days) or make sure that the Internet connection is stable when downloading from Google Drive.
Will new messages disappear when you restore the old copy?
Yes, all messages received after the date the restored backup was created will be deleted. Therefore, before the procedure, it is recommended to make a fresh export of important new chats, if possible.
How often should you make backups for security?
The optimal setting is daily backup at 02:00. This minimizes data loss in the event of a failure. Make sure that the phone is connected to Wi-Fi and charged at this time, or allow backup via a mobile network.
