In mid-December last year, foreign media uncovered that WhatsApp began to test the picture-in-picture function of the iOS version of the video call. During the video call, users can open and operate other programs without interfering with the video call. This feature has existed in FaceTime video calls for a long time, but if you want to video call with Android phone users, WhatsApp is one of the options.
After updating to the latest WhatsApp version 23.3.77, iPhone users can theoretically use the above-mentioned, picture-in-picture function, but some users may have to wait a while because WhatsApp said that picture-in-picture, together with other new features, will be available to users sequentially in the next few weeks.
Other features of this update include adding descriptions when sending files, adding longer descriptions, and themes to groups, and using personalized Avatars as stickers or profile avatars.
