If you use a vivo phone, you can check the QQ face-to-face fast file transfer method:

1. Both parties enter the mobile QQ-click their respective avatars in the upper left corner-enter My Files-the left and right arrow icon in the upper right corner-and find the function of "face-to-face fast transmission (free of traffic)" to enter;

2. After entering the face-to-face fast transmission, choose whether to send or accept the file, and search and select the other party's QQ;

3. When the last party sends it, the other party can receive it.
