Get a Google Pixel and install GrapheneOS.
First Smartphone/OS combo I really enjoy, mostly because this device is fucking secure. I just can't bare non-updatabe CFWs, long forgotten branded roms and Google services...
Problem is things like cars and banks. Some banks now require you to run their app to have online banking. That app refuses to run on rooted devices or custom ROMs, if they can detect it. Some cars have no satnav and require Andrio Auto. Which is in someways is good, but it means there is arm race between FOSS people and car makers + Goings, because of course only they are "secure".
There needs be regulation to protect user freedom/privacy/security and ensure there can be competition to the Google/Apple duopoly.
How about a cave with some art on the wall I could visit on my own time? I hate it when someone interrupts my phone information smoke signals (or smokies as the kids call them these days) and when you miss a puff or two it's impossible to find your place again.
