WhatsApp is launching and testing new features, recently report claimed that WhatsApp group call feature is out and will soon be available for every user but initially you can just add 4 people.
WhatsApp picture-in-picture feature for Android.
Now WhatsApp is working on a new picture-in-picture feature for Android that allows users to play videos from Instagram and Youtube in a tiny window within the messaging apps itself. This feature is useful because you will not need to go to Instagram and Youtube apps to view a video shared by a contact.
When this feature is available on Whatsapp for Android, you will find White colored play icon on and any Youtube or Instagram video link shared by your contact on the messaging app. You just need to tap the button and the tiny box will appear on the screen which is expandable and can be placed anywhere and you can still continue texting.
This PiP support has already been implemented in the iOS app so it will be available for Android soon.
