Android 17 QPR2 has added MTE support for the Pixel 11 series and we've confirmed it works with GrapheneOS with our QPR2 port.

Our port to Android 17 QPR2 is nearly complete. Pixel 11 support can be added after we launch it for the other devices. Completing Signature 27 support is our main priority after QPR2 but we essentially finished Pixel 11 support a long time ago so we can ship that after QPR2 too.
