WhatsApp 2.18.4 beta for Android is now available for download. The latest beta update comes with bug fixes and improvements. In addition, the update has added a new video call switch button. This button is visible when you are in a voice call. When pressed, WhatsApp will send a request to the recipient, asking if he wants to “convert” the current voice call in a video call. The version number is updated from v2.18.1 to v2.18.4. Check out more details below.
