igork When should we expect grapheneos to be released on this OS version?
The developers have been preparing as much as they can without early access to Android 16 code. Hopefully it goes smoothly and it'll be done quickly. If not, it can take a while longer. It's not possible to know how long it'll take before Android 16 is actually released.
igork Will the new design be implemented in GrapheneOS?
I saw a rumor that it won't even be released with Android 16 upstream until later. I don't know if it's true.
Either way, if it's released with AOSP, I'd expect it to be in GrapheneOS.
igork The standard apps look straight out of 2014.
There have been updates to the apps, and I believe there are plans to improve them. I don't know if or how they'll look different after the Material 3 update.
