GrapheneOS resolves significant kernel performance regression in Android 15 QPR1

GrapheneOS developers have successfully identified and patched a major performance regression affecting the Android 15 QPR1 kernel. The issue, which caused significant slowdowns and system instability for users, was traced back to specific changes introduced in the latest quarterly platform release. By implementing a targeted fix, the GrapheneOS team has restored system responsiveness and efficiency, ensuring that the privacy-focused operating system maintains its performance standards. This update highlights the project's commitment to rapid maintenance and stability, even when upstream Android releases introduce critical bugs. Users are encouraged to update their devices to the latest build to benefit from these performance improvements. The fix serves as a reminder of the importance of community-led efforts in maintaining the integrity and usability of Android-based custom ROMs, particularly when official releases from Google experience technical setbacks that impact the end-user experience.
