WhatsApp has been using a picture-in-picture mode since 2018; it is one of the more convenient features. For instance, when you get a video link from YouTube, Instagram, or Facebook, the app allows you to play the video in a small floating window within the chat. You can reply to the messages and watch the video at the same time. The feature has been around for some time, but apparently, it is now getting a refresh.

According to WABetaInfo, WhatsApp is testing a new redesign for picture-in-picture mode to add a new control bar to the video player. The control bar will appear at the bottom of the video and features controls like the pause/resume button, full-screen button, and close button. Previously, these controls appeared, but they did so on the video itself, and well, intruded the overall viewing experience. However, with a dedicated control bar, you will be able to get an unobstructed view of the video feed.
