Google has officially released Android 17 Beta 1, opening public testing for the next major Android update. This early build continues Android’s ongoing focus on stronger privacy and security, smoother day-to-day performance, and a more polished experience overall. It also brings a wave of under-the-hood and developer-facing updates designed to make apps behave better across more device types, especially as large-screen Android hardware becomes more common.
One thing Google has clarified in its beta materials is the naming you may see in different places. In the documentation, the preview SDK identifier appears as targetSdkPreview = “CinnamonBun”, while the official Android 17 emulator system image is labeled “Baklava” in the download instructions. They refer to the same Android 17 preview track, but the different labels can be confusing if you’re cross-checking files or reading developer notes.

Android 17 Beta 1 build number and security patch level
In the official release notes, Android 17 Beta 1 is listed as build CP21.260116.011.B1, with CP21.260116.011.A1 specifically noted for Pixel 6 Pro, Pixel 6, Pixel 6a, Pixel 7 Pro, and Pixel 7. The security patch level included with this beta is 2026-01-05, which is helpful for anyone tracking monthly patches alongside platform upgrades.
How to install Android 17 Beta 1 on a Pixel phone
The easiest way to try Android 17 Beta 1 is through the Android Beta for Pixel program. After signing in with your Google Account and enrolling your supported Pixel device, you can check for the OTA update by going to Settings > System > System update.
Before installing, it’s worth taking Google’s warnings seriously. Beta software can include bugs or performance issues that may disrupt normal use, including battery life, app compatibility, and stability. Google also notes that you generally can’t unenroll and roll back to the stable public Android release without wiping locally stored data, and availability may vary by carrier.
What’s new in Android 17 Beta 1
Android 17 Beta 1 includes changes aimed at apps, performance, and media features, plus platform updates tied to connectivity tooling and companion-device profiles. While many features will evolve between now and the final release, these early changes offer a strong hint at where Android 17 is headed.
Better, more consistent app behavior on large screens
Google is making a notable adjustment for large-screen devices. For apps that target Android 17 (API level 37) on larger displays (Google cites sw ≥ 600dp), Android 17 removes the developer opt-out for certain orientation and resizing restrictions. The goal is more consistent behavior across tablets, foldables, and other big-screen form factors, reducing situations where apps refuse to resize properly or behave inconsistently when rotated.
Performance and runtime improvements
Android 17 also targets smoother UI performance. Google says it’s introducing a lock-free MessageQueue implementation for apps targeting SDK 37 and above, which is intended to help reduce missed frames and improve responsiveness.
On the runtime side, Android 17 adds generational garbage collection support to ART’s Concurrent Mark-Compact collector. In plain terms, that’s designed to reduce the cost of garbage collection, which can translate into fewer slowdowns and better performance consistency, particularly in demanding apps.
Camera and media upgrades, including VVC support
For camera developers and power users, Beta 1 introduces dynamic camera session updates through CameraCaptureSession.updateOutputConfigurations(). This enables switching certain camera use cases without closing and recreating the session, which can improve flexibility and potentially reduce camera lag in apps that juggle different capture modes.
Google’s release notes also mention platform support for VVC (H.266), a next-generation video codec designed to improve compression efficiency. Broader codec support can matter for recording, playback, streaming, and long-term media compatibility, especially as newer formats become more common.
Android 17 Beta 1 is here for Pixel owners who want an early look at what’s next, and for developers who need time to test apps against the newest platform changes. If you rely on your phone for everyday work or can’t risk instability, waiting for later betas (or the stable release) may be the smarter move—but if you’re comfortable testing and providing feedback, this is the starting line for Android 17.
