Twitter seems to be testing a dedicated WhatsApp share button inside its Android app. A number of screenshots showing the experimental feature were tweeted earlier today. In some of the screenshots, the button is placed at the top of the screen next to the search icon and in some others, it is located next to the existing share button below the tweet. Currently, there is a generic share button to quickly post a tweet on Facebook, WhatsApp, or any other app. Right now the company is testing this feature in India, which WhatsApp CEO Jan Koum believes to be one of the countries where its app is growing the fastest.
