Just signed up for your newsletter! I understand you don't want to open up the audio fingerprinting details, but everything else would be very interesting. I am interested in how do you get an old Android phone to run some your APKs headless, how do you update them OTA, how do you power them with solar (I guess you have an external power bank) — some basic questions if I want to put an old Android phone to my DIY project use.

I don't use Android but just did some googling and only have these ideas: roll your APK updates over a custom F-Droid repo, use SSHDroid to log into the headless machine, and/or use one of the DEX patching libraries. How far off are my thoughts?
