I went down the hole of installing Linux on my phone (Samsung Galaxy S7). The easiest path is compiling and installing UBports, some people have heavily started the process but it is still a work in progress.

This is the first part: step by step description to build and boot the system, with helpers scripts to setup the system once flashed.

Small hacky script to set regular temperature changes in 3D printer gcode, to easily use “Temperature towers”.

I had to move my previous Wireguard VPN + Pi-hole ad blocker to another server, but this time I was not able to expose Pi-hole DNS port (53) to the host machine. It was also better to have Wireguard VPN inside a Docker container… so I did!

Moreover, stateless is great when used from a phone as there is no power-hungry keep-alive like OpenVPN, nor reconnection time when switching from Wi-FI to 4G.
