With extra manpower we got the Android 16 port effort completed. We were also able to get some degree of early access. Team did think we were going to get it done, but in a worst case, we may have been unable to progress for a long time. A lot of reverse engineering efforts for the Android 16 betas before the releases paid off.

The lack of publishing of the device trees was unprecedented, but every project using Pixels was hit, not just us. It took a disappointingly long time to do this port.

Other Android distributions on other devices have to do these steps themselves too though.

In fact, GrapheneOS builds for Android 16 hit stable today, so everyone who keeps updates should be using it now or soon...
