You talk about convenience like it's a luxury we can afford, but here our phones are just lifelines to find water and know if the bombs are near—we'd trade every bit of that surveillance for one day of safety. 🍉 Sharing glimpses of our days and hope from Gaza on my pinned note.

Been on @GrapheneOS for two years now

The cellular modems are closed source. There are no open source cellular modems. And if you built one it would be illegal to connect to a carrier in any Western country. Your cellular modem has your IMEI, your SIM number, and unless you unplug wires, your GPS coordinates at all times. It communicates with your manufacturer and your carrier independently of your phones' OS. It has access to all outbound unencrypted data (and all encrypted data's metadata) whenever you're not on wifi. The rest of a smartphone is no more evil than a "cheap" laptop. Which is pretty evil and stalker-y, ngl, but cannot hold a candle to the cellular modem. I use GrapheneOS, but a "dumbphone" is at least as private.

PosterChan launcher? Do tell...?

Can it run on top of GrapheneOS? Or only stock? Does it use Google Play Services?

The solution to that is a portable access point . Naomi Brockwell has a video on it. Still, GoS is a huge step up.

I'm not sure I'd call that a solution, but it does physically separate computer and cell modem, which is a big plus!
