Have you explored File Explorer on your Android phone? If you haven't set up WhatsApp to back up your chats to Google Drive, your Android device will take care of it by saving a local backup.
If you use an external SD card for storage, you can find this backup in the SD Card > WhatsApp > Databases folder.
Android will store the backup on your phone's internal memory if your device doesn't have an SD card.
Remember, deleted messages are only stored in the local backup for a week. So, if you need to recover them, do so within seven days. The exact steps to restore your messages can differ based on your Android version and phone model. Still, they generally involve navigating your phone settings to find and restore the backup. Here are the steps to find:
- Launch File Explorer on your Android device and navigate to WhatsApp > Databases.
- Here, you can view the backup files. The latest backup file is named msgstore.db.crypt12.
- Rename the latest backup file to msgstore-latest.db.crypt12.
- Rename the other older msgstore-YYYY-MM-DD. 1 .db.crypt12 files you want to restore to msgstore.db.crypt12.
- Uninstall WhatsApp.
- If you’ve enabled Google Drive, tap the left menu tab and select Backups.
- You can view the backup files with your phone number in it.
- Hit the three-dot menu and tap Delete Backup.
- Next, reinstall WhatsApp.
- When prompted while setting up, select Restore from backup.
You can try Android Data Recovery Software if this method doesn't work, but don't overwrite your phone by using it excessively.
