GrapheneOS [Unofficial]

Our initial highly experimental release based on Android 16 has been published for all sixteen of the supported devices (Pixel 6 through Pixel 9a). It should only be installed on a spare device you don't depend on. It won't brick devices but there will be broken functionality.

If you have a spare device and want to help test, join our testing chat room. It can be installed either by updating an existing GrapheneOS installation or doing a CLI install. We'll make the staging site web installer use it a bit later. Don't put it on your daily driver yet.

We've received enough feedback for the initial experimental release. There were recent regressions in the port due to SELinux policy changes which resulted in the testing being less useful than expected due to major issues with third party apps which weren't present previously.

We've implemented a workaround for this issue and are also addressing lockscreen UI issues caused by porting our 2-factor fingerprint authentication feature to Android 16. We'll also try to get fixes for various issues related to device-specific configuration being missing too.

Our aim is to have another much more robust and functional experimental Android 16 release in around 8 hours. SELinux policy issue breaking third party app compatibility was unexpected. It only occurred on production builds, not debug builds, so we missed it in earlier testing.

We've found a proper solution rather than a workaround for the SELinux issue. It was caused by an upstream Android 16 change incompatible with how we provided compatibility with several apps banning GrapheneOS including Revolut. We've also included our new overlay automation.
