Hello, how can I upload my novel to an MP4 with my phone?

He could connect his phone to the computer using a data cable and then use the file transfer assistant on the computer to transfer the novel to the MP4. Or you could install a file manager app on your phone and copy the novel to your MP4. However, it should be noted that some mobile phones may not support the direct transfer of novels to MP4. It requires some third-party software or methods to achieve this.
