The PiP works like this. When you’re on a video call and want to multitask by opening another app, quitting WhatsApp will minimize the video chat and allow it to float above other apps. You can move it around the screen with your finger while the video chat continues and the other app you wanted to open is underneath. The feature might not work right away and WhatsApp says it will roll it out over the next few weeks.
WhatsApp adds Picture-in-Picture support for video chat
The update to version 23.3.77 also includes other new features, including the ability to add captions when sending documents to contacts in personal or group chats. You will also be able to use longer topic names and group descriptions when describing a WhatsApp group. Following the update, these names and descriptions can contain up to 2,048 characters, which is a huge increase from the previously allowed 512 characters.
Facebook and Instagram stable friends allow users to create custom avatars and now WhatsApp users will be able to do so as well. To create your own avatar, open the WhatsApp app and go to Settings > Avatar > Create your avatar. Follow the instructions and press Do. This is only the first step. To make your new Avatar the profile picture on WhatsApp, open the app and tap on your profile picture. Then press Modifier > Modifier.
