Google rolled out Android 17 beta 4, the final scheduled beta before the OS ships in mid‑2026. The build, CP21.260330.008, is available on Pixel 6 through Pixel 10 devices via the Android Beta Program. Unlike earlier betas that introduced UI changes, this iteration trims new features to focus on stability and performance polishing.

The headline change centers on app memory limits, a safeguard that caps RAM usage based on each device’s total memory. Google says the limits will curb aggressive memory hogging that causes UI stutters, battery drain, and unexpected app termination. Early testing suggests smoother multitasking and longer battery life, especially on devices with modest RAM configurations.

Developers now face a tight testing window: they must adapt apps for mandatory large‑screen orientation support, local‑network protection, and revised background‑audio rules before the stable release. The beta’s bug‑fix roster addresses several stability issues, but Google urges anyone not on the beta to wait for the final build rather than risk regressions.

Pixel owners can receive the OTA now, sideload the image, or flash the factory build if they prefer a manual route. Early adopters report the update runs noticeably smoother on the Pixel 9 Pro Fold, where the new memory caps prevent the bubble‑style multitasking UI from lagging. The final beta sets the stage for a polished Android 17 launch.
