Whats app, I could not explain the use of this application. My mobile has this application which is running 24 hours. Now, even my higher officials are using it to send important messages to us.
Before, facebook occupied in social marketing era but it can be available on PCs, Laptops and smart phones having high internal memory. But, WhatsApp is running in any smart phone irrespective of its internal memory.
While we using this application, we have to delete the images or videos immediately after we watch them because our phones may struck due to overloading of memory. This is the precaution to be taken while we using WhatsApp.
Unnecessary messages to be avoided while we using this application. We get frustration if real usage is violated with this application.
