WhatsApp released its new version, the 2.17.265 on the beta channel yesterday and it brought a cool new feature with it. The social app now supports picture-in-picture video calls, but it turns out, you need to be on the newest version of Android OS, the Android O to take advantage of the change.
On Android Nougat and below, when you tap back during a video call, the screen goes into the background and the video gets paused while the audio continues. But on Android O, when tapped back, the video screen shrinks down to a floating window. Users can then continue their call — with video — while texting and using the app normally.
Android Police reported that the Picture-in-Picture API was only added in Android O natively, so it’s unlikely this feature would come to WhatsApp on older versions of the mobile OS.
