#GrapheneOS version 2025092700 released.
This release adds official support for using RCS in the Google Messages app if you use Sandboxed Google Play and choose to install it.
Using this requires granting the Phone permission to Play services to provide carrier information to it, granting the required permissions to Google Messages and then setting Google Messages as the current carrier messaging app. Setting an app as the carrier messaging app provides it with device identifier access which is documented in our FAQ. However, Google Messages is a special case where part of the implementation is in Play services. We've dealt with this by special casing the device identifier permission check to detect when the user has granted this access to the official Google Messages app which then also provides the official Play services app with the same access. This doesn't provide any extra access in practice since Google Messages shares the information with Play services. Re-enabling RCS after disabling it isn't expected to work yet and you'll need to clear the app data to enable it.
• add SystemUI and Settings integration for detecting and notifying Pixel 6a users with batteries impacted by the fire hazard issue resulting in capacity and charging being throttled along with directing users to the support options for getting a free battery replacement, $150 credit or $100 cash as compensation for the faulty battery (a subset of this will be replaced by AOSP code when Android 16 QPR1 is finally pushed to AOSP)
• Sandboxed Google Play compatibility layer: add request for the unprivileged READ_PHONE_NUMBERS permission to Play services since it's needed for RCS activation but is not requested since they request the privileged permission instead
• Sandboxed Google Play compatibility layer: when users have granted device identifier access to the official Google Messages app by setting it as the default SMS/MMS/RCS app
• Vanadium: update to version 141.0.7390.43.0
• Vanadium: update to version 141.0.7390.43.1
