In recent news, it was reported that WhatsApp is testing a revamped user interface and a new reply bar for images and videos on Android devices. Before that, WhatsApp allowed users to text unknown phone numbers by creating 'wa.me' URLs using their web browsers.
The feature can be used in situations, for instance, when you need to have a quick chat with a delivery person. It was introduced earlier this year on mobile devices and allows users to quickly initiate conversations with people they don't know so well.
The feature is currently available to a limited number of testers running the latest beta update and it will be available to more testers in the coming future.
