The only problem I see with KDE Connect is that you need to pair the devices. Works great if both are yours, but probably its not something you want leave with the default settings if its shared with someone else.
Miniserve is a program for computers. Though you can run it in termux. It just opens a tiny server instance for file sharing, you can download/upload files to a directory directory. Will also show QR for the link.
