If you accidentally deleted your WhatsApp conversations, so don’t worry, there is a way to recover them very easily because WhatsApp backups all the conversations on its servers. If you want to recover old conversations then you will just have to uninstall WhatsApp from your phone and reinstall it back in your phone. Remember that when you reinstall WhatsApp, it will ask you if you want to restore history or if you want to continue without restoring it. And one more method is there Go to SD card > WhatsApp > Databases and find these two files named (msgstore-yyyy..dd..db.crypt and msgtore.db.crypt ). The first file has all the messages that you have sent or received in last seven days and the second file has the messages of the current day.
