The details on the WhatsApp group video calls remain in paucity until the company either silently releases the update in beta versions, or announces the rollout officially later. Imam also announced that WhatsApp now has over 450 million daily users who are making over 2 billion minutes of video and audio calls on the app. WhatsApp is also adding stickers to the platform, taking a cue from the rival messaging platforms such as WeChat, Hike, and Line. The company said that the sticker service will be open for developers to experiment with their custom stickers and publish them for people to use. There is no word when WhatsApp is planning to roll out the stickers. Finally, the WhatsApp Business app that was launched earlier this year is set to expand with monetisation being planned for the brands. WhatsApp will charge big brands for additional features and support to reach a large user base via the platform. The changes to the WhatsApp Business are expected to be rolled out later this year.
