Whatsapp one of most downloaded Android app.I am sure if you are a smart phone user then you might also be usingWhatsapp.One survey tells that more then 1 billion whatsapp messages are sent daily.
Whatsapp offers a excellent feature last seen option.It will let you know whether the person on other side checked your message or not.Actually this is a best feature but now a days it has becoming trouble for many people.Yes if you want to skip chatting.....
