Today I am giving my bit of knowledge about WhatsApp today millions of peoples are using this application even I use this application scenes 1 yr and I observed that the oldest or the old one application is better than the new one. The reason behind this is in the oldest one the interference is very simple and clear one can easily understand and in the new one the interface is complex and it hard to understand not hard but not so easy that’s why I thought that oldest one is better than new one.
