WhatsApp introduced voice calls in March 2015, first with the invitation and then for everyone. WhatsApp’s calling feature performance was somewhat unstable at first but now it offers a fairly stable service, with less internet consumption. The report also said that WhatsApp calls have been giving tough competition to its competitor Skype, as the competitor skype only has 300 million active users. As per the data from WhatsApp blogpost. The maximum numbers of users of WhatsApp are from India. Approximately, 95% of smartphones users use WhatsApp in India and the app itself also has a setting that helps to diminish the quality of the call to reduce the bandwidth consumption. The WhatsApp has announced that they have already reached 100 million voice calls a day , or what is the same more than 1,100 calls per second. “Today, more than 100 million voice calls are made every day on WhatsApp – that’s over 1,100 calls a second! We’re humbled that so many people have found this feature useful, and we’re committed to making it even better in the months to come.” WhatsApp said in the blog post. WhatsApp has made efforts to offer improved services to its users if we take a look at its latest WhatsApp beta version that is 2.16.188 it includes a “Quick Quote” feature that somehow works similar to some online forum sites. WhatsApp is also working on adding GIF’s feature. “Quick Quote” feature is officially available to all WhatsApp users.
