This is the WhatsApp's view style. It's a try to mimic WhatsApp's volume HUD when watching "stories" in your iDevices. This view style is minimal and elegant giving you a clean look. Due to it's dark background and it's bright colors it will be visible and elegant no matter the background. Since there is no space to play, you can single tap at the speaker to reveal a new view under the main one where you can set the volume level by swipping on it. Welcome to the WhatsApp's experience!
