I recently moved, and the infra provider of the non-profit ISP I use imposes them a two month delay to set up a new fiber line.

During this delay, I met neighbors who accepted to share their WiFi with me. They live a bit far, across the way. The best way I found to get a stable connection with decent speeds was to hang my phone at the top of a window using a salad bag, and share the phone connection to a computer via USB.

I didn't find a way to automatically enable the USB connection sharing before plugging in the USB cable (didn't look for a solution neither, admittedly), so I had to plug the cable, enable the sharing and then put the phone in the bag and adjust the position, all that making sure the cable doesn't disconnect or everything needs to be redone from the start.

I discovered far too late that my distro now has a scrcpy package, which makes enabling the sharing conveniently from the computer.

Yes, I could have tried to ask immediate neighbors instead, probably. I should get my own line this morning, as it happens.

scrcpy is fantastic. I used to write longer texts with it, and now that I can use it again, I'll probably start doing it again.

In recent version of Android, it appears one needs to unlock blindly as the screen is black at this time, I suppose for security reasons.
