whatsApp Android beta users will now be able to directly switch between video and voice calls. The Facebook-owned messaging platform has been testing this feature for over quite a few months now. By introducing this feature, WhatsApp is basically aiming to save user's time when switching between video and voice call or the other way around. The feature is currently available for WhatsApp beta for Android and we can definitely expect the feature to debut soon for all Android users around the world. The rollout timeline is still unknown though.WhatsApp has introduced a dedicated button to switch from video to voice call or vise versa. So, how does this feature really works? Imagine you are on a voice call via WhatsApp with your friend, and suddenly decide to make a video call instead. Currently, to switch between calls, you need to cut the voice call, go back to the chat, and then separately make a video call by clicking on the dedicated video call icon. This consumes a lot of time, and WhatsApp - though late - has now realized that.
