GrapheneOS is a operative system for your phone that's open source and its practically identical to android but its super oriented towards privacy. I left android one year ago and I'm so happy. Its an amazing rabithole. Worth mentioning that I have zero technical knowledge and that it's all well built for like me. I went full on bezerk with this and I took it to the extreme. I'm already one year running with 100% open source apps. I only have 2 proprietary apps :: binance and my local bank :)

There is one catch tho... It only works in pixel phones. This is cuz they can run the "developer options" easily and are more ready for such type of experimentation.
You know what's amazing?? When I look at my phone and I know nobody is listening.
