Google shipped an out-of-band update to droidguard breaking using RCS with sandboxed Google Play. We've already fixed it and it will be included in the OS release we're making later today (2026062300). That will likely be our first Android 17 to reach our Stable channel.

Our 2026062200 release is currently available in our Alpha channel and will likely be available in our Beta channel soon. It may be solid enough to reach our Stable channel but it won't have the opportunity to get there since our 2026062300 release will replace it once it's built, signed and tested.
Google heavily criticized Apple for their closed iMessage ecosystem and initial refusal to implement RCS. Apple then took ages to provide end-to-end encryption support for RCS and it was kept as an iMessage exclusive feature until recently. Google is doing the same kind of thing as Apple with RCS.
RCS isn't truly an open standard or open ecosystem. It isn't open to anyone making a client working with any carriers which can interoperate with the Apple and Google implementations. Google does device integrity checks which supposedly exist to combat spam without testing it works on GrapheneOS.
Resolving most of Google's anti-competitive behavior with Android would be straightforward for regulators: ban the Google Mobile Services licensing model and require Google to make their apps and services work on any AOSP-based OS without privacy invasive access and massive control over the OS.
Android was successful due to being open source and an open platform. Google chose that approach to catch up and get near universal adoption by OEMs and carriers. They've gradually phased in illegal anti-competitive practices making it into a bait and switch. They can be forced to roll it all back.

@GrapheneOS I wish the remedy in the google anti-trust case for chrome and android had been that google had to give both these projects to the Linux foundation.

It wouldn't have been perfect or enough but it would have been fitting so much better than the absolutely no meaningful consequences that they faced.

@GrapheneOS Remember folks, its not illegal if you can pay for enough lawyers to create a legal war of attrition.

They can indeed be forced back into compliance, but who is going to fund it?
