Whatsapp will not be working on some smartphones , as We said last month according to Google they will not be supporting their many of the ssl certified sites to show on some smart phones. That means in phones which are below 7version or KitKat will not be supported to browse through the chrome . So with this said WhatsApp owned by Facebook has announced that even they won't allow their chat application i.e. WhatsApp to run on phones which are even below the Android version on 4.1.3.

This things might find very disturbing to many people who are not economically good . But at the same time the advancement is for the betterment of the futuristic technology and the data optimization . But at the same time the company should give some concession to the underlying areas to use older version as they should atleast know the basics of all about the mobile computing . Again it's all up to them  .
