Starting from iOS17, iPadOS17 and macOS Sonoma, if users use FaceTime or other remote video conferencing applications, Apple has added an expression reaction function when making video calls. For example, when you give a thumbs up, Apple will automatically add video effects such as fireworks to the video. For most non-business activities, these facial expressions can make video chats more interesting.
However, in some serious situations, such as remote video conferences where many people are online, frequent facial expressions may be embarrassing, and this type of problem has also attracted the attention of developers.
In iOS 17.4, Apple has brought a new API to developers. Developers can directly disable the emoticon reaction function by default, so that even if the user does not know that this function exists, there will be no such embarrassment during video conferences.
Apple still turns on the expression reaction function by default. Unless developers update the application and call new APIs for control, there will still be expression reactions.
In this way, developers can control it according to their own needs. On the one hand, video conferencing software can disable this function by default, while ordinary video calling software can enable this function. Of course, users can also provide users with the option to enable and disable it in the settings.
