I found a few old phones from my family. II cleaned them, installed LineageOS and rooted most of them. On one I installed postmarketOS, one is still stock Android and one is lets say bricked (after installing lineagesos it stay on boot logo for ever, before that I installed lineageos and nethunter on it). One one disk encryption doesnt work for some reason.

Phones (all samsung galaxy):

  • S4
  • A5
  • A5 (bricked)
  • A5 (postmarketOS)
  • J3
  • J4+ (no encryption)
  • A31 (stock)

What can I do with them? Something like Monero node or Tor relay, but I’m already running that on old pc. For something that needs speed I have rpis (like a website). Camera security system? Tracking device?

Is it possible to run (and autorun) cli apps and/or services that can access interent, bluetooth, gps, sensors, camera, files, etc. just like on linux? I’m a programmer and I don’t like making normal android apps for a simple project.

    I have a s9+ as a home assistant remote. Put 2 strong magnets in the silicon back cover and stuck it on the fridge.

    Got an automation for the charging, when the battery is at 5% adapter on, at 100% off again… the automation toggles a tradfri switch.

      Nice, I do something similar for my main phone, with the charger at my work place :)

      You could improve the battery life by chaning the automation to charge when below 20% and stop charging at 80%. That way the battery is always between these percentages which apparently is best for it’s health.

      Also deliberately using a slow charger for that setup is also a good idea.
