After much research and testing I have found that GrapheneOS is currently the best security phone operating systems available. “GrapheneOS is a privacy and security-focused mobile OS with Android app compatibility developed as a non-profit open-source project. It’s focused on the research and development of privacy and security technology including substantial improvements to sandboxing, exploit mitigations, and the permission model.” https://grapheneos.org/
“GrapheneOS improves the privacy and security of the OS from the bottom up. It deploys technologies to mitigate whole classes of vulnerabilities and make exploiting the most common sources of vulnerabilities substantially more difficult. It improves the security of both the OS and the apps running on it. The app sandbox and other security boundaries are fortified. GrapheneOS tries to avoid impacting the user experience with privacy and security features. Ideally, the features can be designed so that they’re always enabled with no impact on the user experience and no additional complexity like configuration options. It’s not always feasible, and GrapheneOS does add various toggles for features like the Network permission, Sensors permission, restrictions when the device is locked (USB peripherals, camera, quick tiles), etc. along with more complex user-facing privacy and security features with their own UX.” https://grapheneos.org/
One very interesting point is that Edward Snowden recommended GrapheneOS on his Twitter feed. If you don’t know who Edward Snowden is you can find a lot of good information on Wiki. There are a limited amount of options for secure phones that are a good option for daily use. However, when an internationally known privacy advocate endorses a solution it deserves notice.
Recently, I have been watching videos of Edward Snowden. I would highly recommend checking out the following video. It provides some more information about why security is important. It’s only 10 minutes and it is definitely worth the watch.
