Googlebook finally supports Samsung Galaxy phones with new One UI 9 update

Googlebook expands to Samsung Galaxy lineup

After a lukewarm debut, Googlebook is finally rolling out its cross‑device features to Samsung Galaxy phones. The initial launch limited the service to Pixel devices, leaving the majority of Android users in Europe and North America without access. On 10 October, Android Community Engagement Manager Mishaal Rahman announced on Reddit that the ‘Better Together’ suite would be available on all Galaxy phones running One UI 9 within a few days.

What devices are supported?

Early reports confirm that the Samsung Galaxy S26 Ultra receives the full set of Googlebook capabilities after installing the October security patch. Users of the Samsung Galaxy Z Flip 8 have reported mixed results, with some still waiting for the rollout. Compatibility depends on the device running Android 17, which Samsung labels as One UI 9.

Key integration features

The core features now available on supported Galaxy models include Continue On, Cast My Apps, Quick Access, and Notification Sync. These tools let you start a task on your phone and pick it up on a Windows laptop or ChromeOS device without interruption.

How to prepare your Galaxy phone

Rahman outlined seven steps to ensure a smooth transition:

1. Verify that your phone is on Android 17 / One UI 9.
2. Connect both devices to the same private Wi‑Fi network.
3. Turn on Bluetooth on both devices.
4. Update Google Play Services to the latest version.
5. Update Cross‑device services in the Settings app.
6. Enable the sub‑toggles under Continue activity.
7. Restart both the phone and the companion device.

What Google is fixing

In addition to expanding compatibility, Google has released a patch that streamlines the setup flow for cross‑device services and resolves a QR‑code bug that prevented some users from pairing devices. These fixes aim to reduce the friction that early adopters experienced.

Remaining challenges

Despite the technical improvements, the ecosystem of optimized apps remains limited. Most third‑party apps have not been fully adapted for Googlebook, resulting in a fragmented experience. Until a broader range of apps receive official support, Googlebook is unlikely to replace a Windows PC or Mac for the average consumer.

Future outlook

Google has signaled that further updates will focus on expanding the app library and tightening integration with Samsung’s One UI. If the company can deliver a robust selection of optimized applications, the service could become a compelling alternative for users who already own Samsung Galaxy devices.

Conclusion

For Samsung Galaxy owners, the arrival of Googlebook on One UI 9 marks a significant step toward a more unified Android experience. By following the seven preparation steps, users of the Samsung Galaxy S26 Ultra, Samsung Galaxy Z Flip 8, and other One UI 9 devices can start enjoying seamless cross‑device workflows. The next few months will reveal whether Google can turn this promising start into a truly competitive desktop replacement.
