Breaking Free from Android
Here, the big picture. In the book: the full method and the detailed walkthrough.
Description
GrapheneOS is the most secure mobile OS on the market. It hardens Android deeply: enhanced sandboxing, memory protection, network randomization. Google Play Services can be installed in a sandboxed profile, allowing most apps to run without compromising security. Limited to Pixel phones (the only ones with a properly securable bootloader).
My take
The security reference, recommended by experts. But it requires a Google Pixel and real technical comfort: it's not where I'd advise you to start. Chapter 12.
