I use whatsapp for messaging between platform. I like using it, but it's using a lot of my internal storage data. First time I notice it's using 50+mb of data. I did email the developers, he said to delete all the chats. I did that and the data is still there. the only way to clear it is to go to manage application and "clear data". If I do this, I have to sign in again, use my sms (I have to pay for every sms, that's why I'm using whatsapp), and relink all of my contacts again. Now the data is at 20+mb. Anybody knows how to clear the data without going into manage applications and have to sign in again.
