Wear OS smartwatches can now deliver earthquake alerts even without a phone

Google is expanding the security capabilities of its wearable ecosystem, introducing a major update that will allow Wear OS smartwatches – including models like the Samsung Galaxy Watch – to receive independent earthquake alerts even if they are not paired with a phone. The update comes as part of the latest release of Google Play Services v26.07, which marks a major change in the way emergency notifications reach users.

Personalized notifications come to the wrist

Earthquake alerts in Wear OS previously worked as mirrored notifications. If the user’s phone receives a regional earthquake alert, the watch displays a corresponding alert – meaning smartwatches were only useful if the paired phone was nearby, connected, and turned on. With the new update, that dependency is removed. According to the official changelog, “you can now receive earthquake alerts on your Wear device even if it’s not connected to a phone.”

This transforms Wear OS from a passive utility to an active, independent security tool. Notifications can now come via Wi-Fi or mobile networks (depending on the capabilities of the watch), giving users a much higher chance of receiving alerts in real time. In earthquake-prone regions, even a few seconds can greatly improve safety outcomes – allowing people to take cover, move away from dangerous buildings, or protect vulnerable people nearby.

This move follows recent efforts from Samsung, which improved the earthquake warning functionality in One UI 8.0, strengthening the reliability of warnings on phones. Google’s decision to extend the same initial security push to wearables reflects an industry-wide shift toward stronger emergency communications on personal devices.

Why users should care

For many smartwatch owners, especially those who often leave their phones on the desk, in the gym locker, or charging in another room, this change can be important. Earthquakes strike without warning, and phones are not always available. The watch, however, is always on the wrist – making it a quick point of contact for emergency alerts.

This update is particularly important for residents of regions such as Japan, Turkey, Indonesia, Mexico, and the US West Coast, where real-time earthquake warnings are becoming important public safety tools. Wear OS expands its capabilities meaning more people are reached faster, reducing the risk of missed notifications during crucial seconds.

What remains unclear

Despite the significant improvements, Google has yet to clarify important details. The company did not confirm how the alerts will work independently, or completely rely on a network connection, and whether the feature will work on all Wear OS devices or only those with mobile support. It is also unknown whether Google will extend support to all additional regions or integrate more deeply with national early warning systems.

More information is expected as Google finalizes the rollout and partners begin updating their Wear OS-powered smartwatches.
