What happened to the WeChat video "Floating Balloon"?

The floating balloon of WeChat video may be caused by network instability. It is recommended to check in a stable network environment and try to use WiFi network. If the problem still exists, you can try to change another mobile phone to check. For Apple's mobile phone, if the balloon icon appears in the chat, it may be because the balloon effect in iMessage is enabled, which is a full-screen animation. When making a video call, you can click the function button at the bottom of the screen to enter the special effects window, find and open the beauty effect, and then see the beauty effect in the video call interface. If you need to turn off the beauty function, just enter the Special Effects window again and click Remove Beauty Effects.
