WhatsApp is always working to add new features to its app, so it’s no surprise that beta users are already seeing some options that are not yet available to anyone else. The new feature that’s available for WhatsApp beta users on Android allows them to share audio content during a video call.
This feature was originally released in a previous beta version of WhatsApp for iOS, so it’s safe to assume that the ability to share audio over video calls will eventually come to both iOS and Android platforms.
