So you know... https://xkcd.com/949/ I have this thing, I often want to transfer a couple of files to my android phone from a Linux laptop. I do this by connecting the USB cable, mounting mtpfs, copying. I don't feel this is a good way. Any cable-free, simple alternatives?
I use SSHDroid, but they later nerfed it not to support pubkey without purchase and the purchase doesn't work without gapps so I tweaked its shell scripts as root to fix...
