Facebook-owned WhatsApp recently introduced some interesting features in order to enhance the app's user experience. Now, the company is testing to a new feature which will enable the users to switch between voice and video calls. Along with this, WhatsApp is reportedly working on a new app, targeted towards businesses.

As per WaBetaInfo (@wabetainfo), a Twitter account that tracks changes in WhatsApp's beta builds, WhatsApp is testing a new feature on Android which will allow the users to switch from voice calls to video calls (and vice- versa) without disconnecting. Currently, users have to end a voice or video call in order to switch between them.

WaBetaInfo has also noticed a change in the UI of the app. After the roll out of the feature, it seems that users will have a new video call button placed at the bottom of the display, when they are on a voice call. So, if users want to switch the call, then they just need to tap on the video button to activate the camera and start the call. Once done, the recipients will get a notification as to whether they want to accept or reject the call.

Along with this, WaBetaInfo has revealed that WhatsApp is working on a new app for small and medium businesses. The app will be available for Android, iOS and Windows 10 Mobile platforms. Businesses will be able to communicate with their customers and vice-versa using the app.
