You have it backwards. It's smartphones other than iPhones and Pixels with the front door open due to lack of basic security patches and protections. You're making unsubstantiated claims about backdoors not backed by any evidence. Those claims can be made about ANY available hardware. Using devices without basic privacy/security patches for firmware/drivers, an end-of-life Linux kernel and lack of important hardware-based security features is the opposite of being serious about security.

The reason GrapheneOS has an OEM partner we're working with towards their at least one of their upcoming devices meeting our requirements is because Pixels are the only currently viable options. If other OEMs were making reasonably secure devices with support for using another OS on their own, we wouldn't need OEM partnerships. The currently available devices from our OEM partner don't meet our security features or update requirements, but a subset of their future devices will. GrapheneOS will be officially supported so it will be easier to provide a fully production quality OS and we'll be able to do lower level privacy and security improvements at a hardware, firmware and driver level.
