Why does WeChat video have special effects than the heart?

The telepathic effect in the platform video is due to the interesting features added by WeChat in the iOS 17 system.

When you make a gesture of sympathy in WeChat video chat, the system will automatically trigger the corresponding animation effect. The appearance of this special effect increases the interest of video chat and makes users get a better experience in the use process.

This special effect is not limited to iOS users. Even if the other side of the video call uses an Android phone or has not upgraded to iOS 17, they can still see this special effect, but they can't trigger it. This design enables all users to enjoy this interesting special effect in video chat, and enhances the interaction between users.
