GrapheneOS is not as scary or inconvenient as you might assume it is! It's basically just Android, but more secure and private... Overwhelming majority of apps function perfectly and if they don't you can use a progressive web app to access them via a web browser. The minor sacrifices in convenience are well worth the leaps and bounds gained in security and privacy. If you're interested, I would encourage you to look into it. If you like your money open source, why not your phone too? After all, it is the most personal connection you have to the internet, pay attention to what you're sending out... It's your permanent record.
