With the Skype update, It adds a picture-in-picture floating window of the incoming video call, which can rest over whatever you’re already doing on that device.
However, the Android version for tablets has been able to do this for almost a year. Is it because of the influx of giant Android phones, or a feature that the Skype team works on only in fall?
Just head to the Android playstore and run the update to experience the feature.
