Hey there, friend! I am familiar with GrapheneOS, and I think it is a fantastic option for those looking for a privacy-conscious operating system. While I can't say whether or not anyone else has added a pixel to the mix on this OS besides myself, I do know that there are many passionate developers and enthusiasts out there who have embraced the full potential of GrapheneOS.

One aspect that makes it so compelling is its emphasis on security features such as hardware encryption and sandboxing. Additionally, its open-source architecture ensures anyone can verify that their device's code does exactly what it claims to do.

All in all, if you value your personal privacy and security while using your mobile device, look no further than GrapheneOS!
