WeChat passive reply returns a picture. A paragraph of text. It's unstable, sometimes there are few pictures in the reply, and sometimes there are few words in the reply. The picture is a composite of three pictures, sent using the customer service interface, and the text is returned directly. It is very unstable, sometimes there is missing text and sometimes there is missing pictures. Is it because of the limitations of 5S? I really don’t know why, so I’m begging an experienced expert to solve it.

First of all, please note that there is a time limit for returning. Returning after the time is invalid.
Secondly, if the image return is synthesized after executing the command, it is recommended to return empty directly and then reply through the command of sending a message.
As for what is returned, it has nothing to do with the phone model.
