Android 17 (codenamed Cinnamon Bun¹) is the seventeenth major release of the Android mobile operating system, developed by the Open Handset Alliance led by Google. The first public beta was released on February 13, 2026.²

Google shifted the development cycle for Android 17, moving away from the traditional "Developer Preview" phase in favor of an earlier public beta release. This accelerated timeline is intended to align with hardware launches in the first half of the year.

The initial Beta 1 release carries two primary build identifiers:

• CP21.260116.011.A1: For Pixel 6 through Pixel 7 series.
• CP21.260116.011.B1: For Pixel 8, 9, and 10 series, including Tablet and Fold models.

• Enhanced large screen support: Apps targeting Android 17 (API 37) are now required to be resizable, effectively eliminating "letterboxing" on tablets and foldables.
• Predictive Back 2.0: Refined animations for the predictive back gesture, providing more consistent previews of the preceding screen.
• Gemini integration: A new "screen shrink" animation when invoking the Gemini assistant via corner swipes.

• VVC (H.266) support: Native support for Versatile Video Coding, offering superior compression for high-resolution 8K video.
• Loudness Management API: A system-level tool to prevent sudden volume jumps when switching between different media applications.
• Camera improvements: Optimized transitions when switching between physical camera lenses (e.g., Wide to Ultra-wide) to reduce frame jitter.
• Generational garbage collection: An update to the Android Runtime (ART) that improves memory management efficiency and reduces system micro-stutter.
