There are many applications to chat with your contacts on Android and iPhone but after being using Android devices for three years, it would not wrong for me to say that WhatsApp is one of the best applications that I have come across till now. Using internet connection you can chat with any of your friends on your phone that too free of cost (other than the one you spent for internet).
Recently I have restored my device to defaults; I noticed that all my previous chat messages have been deleted. You would probably know that WhatsApp by default creates a backup of your chats at a scheduled time but that feature also proven useless for me as it was unable to restore my previous chats.
This could be because of some error or anything else. While searching a solution for this issue, I have come across an online application that helped me a lot. Thus it would be worthy to share it on this blog. The application is known as Recover Messages that allows you to recover your deleted WhatsApp messages on your iPhone and Android device. In other words you can say that it serves as a Forensic tool for your device.
How to locate the WhatsApp database file on your device
