How to recover deleted WhatsApp messages
1. Through local storage
This method only works for Android users, not for iOS users.
First of all open your file manager.
Go to WhatsApp folder here, then click on Database.
This folder contains all the backup files of WhatsApp.
Press the file named msgstore.db.crypt12 for a while and edit the name.
Keep the new name msgstore_backup.db.crypt12. This was done because it would not replace the new file.
Now name the latest backup file msgstore.db.crypt12.
Now go to Google Drive and delete your WhatsApp backup.
Now reinstall WhatsApp after uninstalling.
When you start WhatsApp again, it will ask for backup from local storage.
After selecting the msgstore.db.crypt12 file here, tap on Restore.
Now you will get your message.
2. via Google Drive or iCloud
This method can be used by both iPhone and Android users.
Reinstall WhatsApp from your smartphone after uninstalling it.
When you start WhatsApp again, it will ask for backup from Google Drive or iCloud.
Restore the backup.
Your message will also come back with full chat.
