In May, we began preparing to port to Android 16 despite our most active senior developer responsible for leading OS development being unavailable. Android 16 launched today and porting is going to be significantly more difficult than we were expecting.

We did far more preparation for Android 16 than we've ever done for any previous yearly release. Since we weren't able to obtain OEM partner access, we did extensive reverse engineering of the upcoming changes. Developers also practiced by redoing previous quarterly/yearly ports.

Unfortunately, Android has made changes which will make it much harder for us to port to Android 16 and future releases. It will also make adding support for new Pixels much more difficult. We're likely going to need to focus on making #GrapheneOS devices sooner than we expected.

We don't understand why these changes were made and it's a major turn in the wrong direction. Google is in the process of losing multiple antitrust cases in the US. Android and Chrome being split into separate companies has been requested by the DOJ. They may be preparing for it.

We're hard at work on getting the port to Android 16 done but there's a large amount of additional work we weren't expecting. It can be expected to take longer than our usual ports due to the conscription issue combined with this. It's not good, but we have to deal with it.

Having our own devices meeting our hardware requirements (https://grapheneos.org/faq#future-devices) would reduce the time pressure to migrate to new releases and could be used to obtain early access ourselves. Based on talks with OEMs, paying for what we need will cost millions of dollars.

Maybe get a small preorder thing going just to test first batch?

It would need to be more than that, since a lot of projects like that end up being dead wood that isn't maintained, and therefore don't end up being secure at all. We'd want an OEM to build since there can be some assurance there will be maintained security updates and patching for years down the line.

GrapheneOS needs the same requirements or effort Pixels have, else there's security or functionality shortcomings and it misleads our users.

That is really a bummer to hear as graphene is a great project. On a somewhat related note, I do find it interesting that when users on your forum used to post messages asking about the dangers of google making it harder for 3rd party OS's like nostr:nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpq235tem4hfn34edqh8hxfja9amty73998f0eagnuu4zm423s9e8ks3f750r to be used on their hardware in the future, they were largely told they were being hysterical and that google hasn't done anything like this in the past and wasn't planning to do anything like this.

I guess those users had a point to be worried about longevity of the project before investing time/money/effort in switching to a niche OS like graphene

We've made a lot of progress on porting to Android 16 already. If things hadn't been made harder for us, we would likely be able to publish an experimental release tomorrow and quickly get a release into the Alpha and then Beta channels to start ironing out the bugs in the port.

We have early builds of #GrapheneOS based on Android 16 booting in the emulator. We would usually be working on quickly porting over device support and getting the kernels ready including doing the production kernel builds now. Unfortunately, that will be harder than usual.

Our speculation about this is that a result of Google losing a US antitrust case and likely losing several more soon, they're preparing for Android and Chrome being split into separate companies. If Android gets split off, they want to retain Pixels.

Google seems to be in the process of splitting up Android and Pixels along with moving towards treating other Android-based platforms as their competitors instead of their partners. Pixels retain first class alternate OS support with Android 16 firmware so it's not about that.

Thanks for the update. I hope main development branch of Android can stay opensource even after splitting off from GOOGLE.

So the upcoming Pixel 10 devices and onwards can't be used with #GrapheneOS anymore?
