In the video of WeChat and the other party, you enter information on your mobile phone. Can the other party know the content of the information?

At the same time as the other party's video, many programs on our mobile phone are not affected. For example, suddenly I don't have a short message record. Whether it is the short message on our mobile phone or the message on WeChat, the other party can't see it at all. Where is the other party? First, we chatted with the longest video. The other party saw our faces and backs through the camera. What about this camera? If there is no mirror behind, take out the money without a mirror, and the other party can't see our information. If there is a mirror behind, the mirror can reflect light and refract the information on our mobile phone, then the other party can see it. In addition to this situation, there is basically nothing else.
