Android 16 QPR2 Brings Smarter Features
Google’s December 2025 quarterly update delivers AI-powered notification tools, advanced customization, and critical security fixes to Pixel devices
Google released Android 16 in June 2025, but the December 2025 update represents a different approach to Android development. The company is now delivering more frequent platform releases instead of a single yearly update. This December release, officially called Android 16 QPR2 (Quarterly Platform Release 2), marks the first minor SDK release in Android history.
The update rolled out on December 2, 2025, to Pixel devices from the Pixel 6 series through the Pixel 10 lineup. According to Google’s official blog, the release brings AI-powered notification summaries, a notification organizer, and expanded customization options. The update also includes fixes for 33 device-specific bugs and patches for 107 security vulnerabilities.
Update at a Glance
The QPR2 update follows Android’s new accelerated release schedule. Google released Android 16’s major version on June 10, 2025, moving the typical fall release to Q2 to align with device launches across the Android ecosystem. The company now plans a major release in Q2, feature releases in Q1 and Q3, and a minor SDK release in Q4.
This approach allows Google to deliver new APIs and features more rapidly without the behavior changes that typically require extensive regression testing. The December security patch addresses vulnerabilities ranging from High to Critical severity across the Framework, System, and kernel components.
