Deleting a contact from the phone book on Samsung Galaxy often leads to panic: not only the subscriber's data disappears, but also all correspondence on WhatsApp. In fact, chats are not permanently erased; they can be returned even if you have already cleared your message history. The main thing is to act quickly and choose the right recovery method.

Many users mistakenly think that deleting a contact automatically deletes the correspondence. This is not true: messages remain in the messenger database, but become invisible in the main interface. You can restore them through backups, hidden settings, or even third-party utilities - but each method has limitations. For example, if you have already reinstalled WhatsApp after deleting a contact, the chances of returning chats without a backup are close to zero..

This article contains proven methods for Samsung on Android 10-14, including models Galaxy S23, A54, Z Flip and others. We will analyze both official solutions from Metaand alternative approaches for complex cases. Important: some methods require root access working with system files - this may violate the warranty or stability of the device.

Before you start, check:

  • 📱 Phone model Android version ( Settings → About phone)
  • 🔄 Last date backup Whatsapp (⋮ → Settings → Chat → Backup)
  • 📁 Free space on the device (minimum 1 GB for file manipulation)
📊 Have you already tried to restore the correspondence WhatsApp?
Yes, via Google Drive
Yes, via local backup

The easiest way is to return the deleted contact to the phone book. If you haven't cleared your chat history manually, the conversations will appear automatically after synchronization.

How it works:

  1. Open the application Contact on your Samsung.
  2. Click + (or Create contact in older versions).
  3. Enter exact phone number remote subscriber (including country code).
  4. Save the contact and restart WhatsApp.

The chat should appear in the list of dialogs in 5-10 seconds. If this does not happen:

  • 🔍 Check if the chat is hidden (scroll down the list to the section Archive).
  • 📶 Make sure you have access to the Internet (WhatsApp synchronizes data).
  • 🔄 Update the application to the latest version in Galaxy Store or Google Play.
⚠️ Attention: If you deleted a contact to creating a WhatsApp backup, this method will not restore messages older than the date of the last backup. For example, if the backup was on May 1, and the contact was deleted on May 10, correspondence from May 1 to May 9 will remain unavailable.
💡

If you do not remember the contact number, check your call history in the standard application Phone or in Call log. Even deleted contacts can be displayed there for 30 days.

2. Using local backup WhatsApp

WhatsApp automatically creates local backups every day at 2:00 am (if the phone is connected to charging and Wi-Fi). These files are stored in the device memory and can save correspondence even after deleting the contact.

Instructions for Samsung:

  1. Connect the phone to the PC via USB cable (mode File transfer).
  2. Go to the folder Internal Storage → WhatsApp → Databases.
  3. Find a file named msgstore.db.crypt14 (or crypt12/13 for older versions).
  4. Copy it to your desktop and rename it to msgstore_backup.db.crypt14.
  5. Delete WhatsApp and install again from Google Play.
  6. When you first start the messenger will offer to restore chats from a local backup.

If the backup file is missing:

  • 🔎 Check the folder sdcard/WhatsApp/Databases (for devices with a card memory).
  • 📅 Make sure that there is enough space on your phone to create backups (minimum 500 MB).
  • ⚙️ Enable automatic backup in WhatsApp settings (Chat → Backup → Local).
Whatsapp version Backup format File location Features
2.21.15 and later msgstore.db.crypt14 /sdcard/WhatsApp/Databases Requires Google Drive for cloud backup
2.12.45 – 2.21.14 msgstore.db.crypt12 /storage/emulated/0/WhatsApp/Databases Supports local backups without cloud
Old versions msgstore.db.crypt8 /data/data/com.whatsapp/databases Requires root access for extraction
⚠️ Attention: Do not rename the backup file after reinstall WhatsApp. The messenger looks for a file with the original name (msgstore.db.crypt14) and ignores the modified copies.

3. Restoring via Google Drive (cloud backup)

If your Samsung backup to Google Driveis enabled, you can return correspondence even after completely reinstalling WhatsApp. This method only works if: Google Drive contact.

  • 🔗 Account Google the same as when creating a backup.
  • 📅 The latest backup has been created to delete a contact.
  • 📱 There is enough space on the phone to download the archive.

Step-by-step guide:

  1. Delete WhatsApp via Settings → Applications.
  2. Install the messenger again from Google Play.
  3. When you first start, enter the same phone number as before.
  4. Click Restorewhen the backup request appears from Google Drive.
  5. Wait for the process to complete (may take up to 30 minutes depending on the size of the archive).

If recovery does not start:

  • 🔄 Restart your phone and try again.
  • 📶 Connect to Stable Wi-Fi (mobile data may interrupt downloads).
  • 🔑 Make sure you have enough storage space Google Disk (15 GB free).

Important: WhatsApp restores only the latest backup. If you created an archive after deleting a contact, the correspondence will not be returned. Also, this method does not work if you changed your phone number or account Google.

What to do if Google Drive does not find the backup?

If WhatsApp does not see the archive in Google Drive, check:

1. Account correctness — you must be logged into the same Google account as when creating the backup.

2. Synchronization settings must be enabled —in Google Settings → Backup the option WhatsApp.

3. Date of last backup — if the archive is older than 1 year, it can be automatically deleted from the cloud.

4. Regional restrictions — in some countries (for example, China) Google Drive is blocked, you will need a VPN.

4. Recovery through third-party utilities (without root)

If standard methods do not work, you can try specialized apps for extracting data from WhatsApp backups. These tools analyze files msgstore.db.crypt* and recover messages even without an active account.

Top 3 proven utilities for Samsung:

  • 🛠️ Dr.Fone – WhatsApp Transfer (supports Android 10-14, does not require root).
  • 📱 iMobie PhoneRescue (works with encrypted backups crypt12-14).
  • 🔍 Backuptrans WhatsApp Transfer (allows you to export chats to HTML or PDF).

Instructions using an example Dr.Fone:

  1. Download and install the app on your PC (Windows or Mac).
  2. Connect Samsung via USB (enable USB debugging in Settings → About phone → Build number).
  3. Select option Whatsapp data recovery.
  4. Follow the app prompts to scan the device.
  5. After analysis, select the desired chats and export them in a convenient format.

Limitations of methods:

  • 💰 Most utilities are paid (free versions restore only part of the messages).
  • 📅 Restoration is possible only from existing backups (apps do not “recover” deleted files).
  • 🔒 Some utilities require disabling Knox protection on Samsung, which may lead to the warranty being reset.
⚠️ Attention: Do not use apps that promise recovery without backups (for example, “recovering deleted messages directly from WhatsApp servers”). This is a scam. — WhatsApp does not store user messages on its servers after delivery.

5. Manually extracting data from backup (for advanced)

If you have root access on Samsung, you can manually extract correspondence from backup files. This method is suitable for technically savvy users and requires working with ADB or file system.

Required tools:

  • 🖥️ PC with installed ADB Tools and SQLite Browser.
  • 📱 Samsung with unlocked bootloader and root access.
  • 🔌 Cable USB Type-C (original for a stable connection).

Step-by-step process:

  1. Connect your phone to the PC and open ADB Shell:
    2. adb shell

    su
    

    cp /data/data/com.whatsapp/databases/msgstore.db /sdcard/msgstore_backup.db
    

    exit

  2. Copy the file msgstore_backup.db to your computer.
  3. Open it in SQLite Browser and export the table messages to CSV.
  4. Use the script on Python (for example, whatsapp-parser) to convert the data into a readable format.

Alternative method (without ADB):

  • Using Root Explorer find the file /data/data/com.whatsapp/databases/msgstore.db.
  • Copy it to folder Download.
  • Use the online service WhatsApp Viewer to view messages.
⚠️ Attention: Working with root access on Samsung may result in triggering Knox (indicator 0x1), which voids the warranty and blocks some functions (for example, Samsung Pay or Secure Folder).
💡

Manual extraction data is the only way to return correspondence if all backups are overwritten or deleted. However, this method requires deep technical knowledge and is risky for beginners.

FAQ: Frequently asked questions about restoring WhatsApp correspondence

Is it possible to restore correspondence if I have already reinstalled WhatsApp after deleting the contact?

Yes, but only if you have one cloud backup in Google Drive or local copy file msgstore.db.crypt14. If there are no backups, recovery is impossible - WhatsApp erases the data upon uninstallation.

Exception: if you use Samsung Smart Switch to transfer data, the correspondence may be saved in the phone backup (check Settings → Accounts and archiving → Backup and recovery).

I deleted the contact and cleared the chat history on WhatsApp. Is there a chance to return messages?

The chances are minimal. Clearing history manually (Delete chat or Clear chat) deletes messages irreversibleeven if the contactlater is restored. The only option is to check if screenshots or exported copies of the chat are saved on the device.

If clearing has occurred to creating the latest backup, try restoring from an earlier backup (for example, via Google Drive or a local file).

How to restore correspondence on a new Samsung phone if the old one broken?

  • 📱 The phone number is the same as on the old device.
  • ☁️ Account Google the same as when creating a backup.
  • 📅 The latest backup has been created before phone breakdown.

If there is no cloud backup, but the old phone turns on (even with a broken screen), connect it to the PC and copy the folder WhatsApp/Databases.

Is it true that WhatsApp stores all messages on its servers and they can be restored through support?

No, this is a myth. WhatsApp uses end-to-end encryptionand messages are stored only on users' devices. Support cannot restore correspondence, even if you provide evidence of the importance of the data.

Exception: if you have enabled Backup to Google Drive, the data is stored in encrypted form on Google servers, but is available only to you.

  • 🔋 Low battery —charge your phone to 50% or more.
  • 📁 Lack of space —free up at least 1 GB memory.
  • 🔑 Changing Google account —log in to the account where the backup was created.
  • ⏳ Outdated version WhatsApp —update the application to Google Play.

If the problem persists, try:

  1. Delete the folder WhatsApp manually through the file manager.
  2. Restart the phone.
  3. Install WhatsApp again and repeat the recovery.
