GrapheneOS not only leverages the same hardware-based security features as the OS but implements major hardware-based features unavailable elsewhere.
Hardware memory tagging for production hardening is an exclusive GrapheneOS feature with a best-in-class implementation.
Our USB-C port and pogo pins control feature does hardware-level attack surface reduction with code written for the drivers on each device:

Our Auditor app leverages the pinning-based hardware attestation available on Pixels based on our proposal for it.
Many of our other features are hardware-based, and some of these exist because of features we proposals or helped to secure against weaknesses.
In April, Pixels shipped reset attack protection for firmware based on our proposal, which is not available on other Android devices.
@GrapheneOS Should have led with this and I wouldn't have had to read any further. Anything involving that dbag is automatically suspect on so many levels.
Thanks for all your work.
