One complaint I have of the Samsung Galaxy Note 8 (and all the Samsung Galaxy phones I know of) is that sharing files from a windows machine to the Samsung Galaxy Note 8 phone via SMB is incredibly slow. I suspect it’s because this method doesn’t make the phone exit power save, but I can’t be sure. It’s something I’ve written about before and I’ve only just now thought of an obvious solution.
If you share a folder to a linux machine, you can then connect to that machine. If you don’t have a linux machine, you can either run virtualisation software and install CentOS or Debian (it’s completely free) or buy a Raspberry Pi 3 B (you could technically do it with a Raspberry Pi Zero W as well.)
I’m a bit tired now, but this idea suddenly came to me and I will write about this further tomorrow at the previous page I’ve made. The idea is you can then connect to the intermediary box using the phone, and then browse to the network file share–it’s sort of like accessing a share within a share.
It’s arguably convoluted but it’s also arguably more secure because you can use an SSH key and disable passwords altogether. On the windows machine, you can limit the network share to the IP address of the Raspberry Pi 3 B (or virtual computer) and then the only theoretical way of accessing the file is from an SFTP share.
