Turn an old Android phone into a Local AI Voice Assistant

I had a nice old cracked pixel 5a laying around that I wanted to get some use out of, so I turned it into a local AI Voice assistant. A server on a laptop running llama.cpp gemma-3-4b-q4.gguf served by flask connects to a script running on the phone. scrcpy was used to access the phone, setup termux, and ssh in.
Here's the repo! https://github.com/pioneermushrooms/termux-node-assistant

Script sets up a config file on the first run. You might be able to get this up and going in under 10 minutes.

I ask it how the weather's going to be, or other random questions I think of while I'm putting on my shoes.

Note: On my pixel 5a I could start the server via ssh and termux would always listen. On my pixel 7, I had to type directly into my phone for termux mic to activate. Maybe because I installed via playstore there, and not apk. Maybe you don't have a pixel and don't care!
