>> Modern smartphones however, seem like walled gardens in which I have no control at all. By design, I think. >> I am locked into a single OS on my smartphone, which either spies on you or is locked down even more. Every iteration a bit more control is taken away from the user. I got so fed up with this, I abandoned the whole mobile infrastructure and built my own phone with a Raspberry Pi 3B+. The Raspberry Pi is pretty open hardware (yes, I'm aware it's not perfect). For software I used Python 3, C and GTK. It does voice and SMS/MMS only, but that is enough for me. I built it for myself. It's stable enough that I use it as my daily driver. I am in the process of open sourcing the code and putting it out on github. https://github.com/another2020githubuser/thepyphone https://github.com/another2020githubuser/thepyphone I truly hope an open hardware smart phone becomes available soon. Until then, I'll use my home grown PyPhone to get by.
