They are doing a good job, but GrapheneOS exceeds in quality of the implementation.
For example, sandboxed Google Play runs actual version signed by Google but with no system level access. All other forks either runs Google Play at system level or runs a spoofed version breaking security model of Android.
It's really impressive what GrapheneOS is doing. With a such a small team, they are able to push so many features that just works. I think average consumer does not realize the value of this project. With constant surveillance of Apple and Google, GrapheneOS is the only high quality alternative we have. Whoever reads this, please use GrapheneOS and donate if possible.
This is incorrect. It strengthens both privacy and security in a lot of ways for an average user.
Your English is perfect. There is no indication of low intelligence from the way you described your issues. B and C grade are pretty average and indicates you can learn with hard work. I think what you might be experiencing is anxiety and that is causing you to think you don't have skills or intelligence. I am not from US so I don't know what kind of help might be available for you there, but I would suggest you to look for a job with something you like to do even though the pay might not be great and then eventually your interest will take you further in your career.
That explains why MullvadVPN keeps disconnecting on Android.
FSF does not get in the way of security. FSF believes source code should be publicly available in order to even assume the software is secure or private. In a perfect world that would be nice. But in the real world, proprietary blobs are required to make the hardware functional. As long as OEMs are removed about open sourcing the firmwares, both GrapheneOS and GNU are right in their own way.
GrapheneOS is the easy to install OS among any mobile platform. Everything is through a web UI, so you are very unlikely to brick your phone. You don't need to type a single command. Also even if you brick a Pixel phone, it's very easy to install stock Android build through Google with a similar installation process.
GrapheneOS is a security and privacy focused mobile OS with Android app compatibility.
After using LineageOS for long time, I have finally moved to GrapheneOS. I use a lot of banking and financial apps which I never felt comfortable using on LineageOS due to lack of proper sandboxing, unlocked bootloader etc.
GrapheneOS works flawlessly just like Android. You don't even notice there's hardening underneath. Also it protects from Google's evil location tracking using WiFi/Bluetooth or even when the Location is turned off. I don't understand how people in general are comfortable with Google tracking all the time. You can use Google Play and Play Services in a sandbox that works just like regular installation, but without deep tracking.
If you haven't tried GrapheneOS, try it. You won't go back to regular Android.
Yep. It was developed to improve parallelization and security of Firefox. Many core parts of Firefox have been replaced with Rust implementations.
