GrapheneOS has fixed the Android 17 QPR1 kernel performance regression
3 hours ago
- Android 17 QPR1 was released for Pixels on September 15, but introduced a kernel regression causing stuttering, lag, and freezes under memory pressure.
- GrapheneOS fixed the regression in their own release after updating firmware and drivers, but Google's fix is delayed.
- Google typically takes 2–3 months to ship fixes for severe regressions and security issues, and their release engineering process is broken.
- The Pixel 11 series received a bug fix update near September 2026 with the 2026-09-01 patch level, which was not Android 17 QPR1 and lacked the September firmware/driver security patches.
- GrapheneOS reduced memory usage from their secure spawning feature and plans to ship the improvement before November 2026.
- The commit fixing the Android 17 QPR1 regression is available on GitLab.
