Eggplant So far there is zero indication that Motorola is planning to change the hardware design of upcoming 2027 devices to run GrapheneOS, let alone that Motorola is hoping users will chime in suggesting new hardware features, or that the GrapheneOS project will suggest new hardware features.
It seems pretty clear that the plan is for Motorola to ship in 2027 exactly a phone they have already designed in 2026, and for Motorola and GrapheneOS to collaborate on the software.
If that goes well, who knows, maybe Motorola will be open to hardware feature requests. But it seems unlikely that Motorola will ship a special phone model for security and privacy enthusiasts, and adding hardware features to general-audience models has real risks. There are already plenty of complaints here from users who want a way to disable the green dot displayed when an app is using location. Shipping a hardware camera/microphone LED that could not be disabled would need to balance what I suspect is a small number of people who would really like it against a large number of people who would really hate it. That tradeoff may make sense for a small company who is fine with limiting themselves to a tiny market, but it seems unlikely that a large-volume company would risk poor sales for a model by forcing that feature on all of their customers.
For Motorola/GrapheneOS devices in 2028, 2029, etc., I think invisible security enhancements are much more likely to be added than in-your-face features that will cost real money and will offend many users.
