Samsung’s One UI 8.0 is introducing a beefed-up earthquake alert system that goes beyond what Google currently offers on standard Android devices. While Google’s Android Earthquake Alerts System has been gradually rolling out to more regions and devices, Samsung appears to have built its own version tucked inside One UI 8.0—complete with customization options, emergency resources, and a native One UI feel.

Earthquakes can strike with little warning, and early alerts—sometimes mere seconds before shaking begins—can make a real difference in safety. Over the past few years, Google has partnered with seismic data networks to push Android Earthquake Alerts System notifications to supported devices in high-risk regions. These alerts aim to give users a brief lead time to “drop, cover, and hold on,” potentially reducing injuries during initial tremors. However, that core functionality—while invaluable—has largely remained a one-size-fits-all implementation: an alert appears with a sound and full-screen message when seismic data indicates imminent shaking in your area.

Studies and anecdotal reports show that even a few seconds can allow people to move away from hazards (shelves, windows, heavy machinery), pause critical tasks, or send quick notifications to loved ones. But beyond the raw alert, additional context or preparatory steps could further aid users in emergencies. This is where Samsung’s version steps in.

Tipster GalaxyTechie uncovered that One UI 8.0 includes an “Earthquake Warnings” module (version 1.0.07.0) that feels native to Samsung’s design language—unlike prior alerts on One UI 7.x or the current public beta of One UI 8.0, which leaned on Google’s standard approach. Samsung hasn’t officially highlighted this in its published changelog, suggesting it’s quietly rolling out or still in testing. Screenshots shared online reveal a dedicated settings page under Settings > Safety and emergency > Earthquake warnings, complete with intuitive toggles, descriptions of seismic intensity levels in simpler language, and time-slot differentiation (day vs. night thresholds).

One of the standout additions is the ability to set custom “seismic intensity” thresholds for when the alert triggers. Where Google’s system might use a preset magnitude threshold (e.g., magnitude 4.5+ in many regions), Samsung lets users choose their own sensitivity levels—reportedly ranging from as low as 1.0 (barely noticeable tremors) up to around 4.0 or higher, depending on region and local interpretations of seismic scales. Moreover, you can set separate thresholds for daytime and nighttime, acknowledging that users might prefer fewer false alarms when they’re asleep, or conversely, want higher sensitivity at night when vulnerability feels greater. Below the chosen threshold, the system will still display a non-intrusive banner but won’t interrupt ongoing activities—allowing people to gauge severity without abrupt distractions.

Samsung adds a “preview” function so users can test how an earthquake warning would look and sound on their Galaxy device. This helps demystify the sudden pop-up and ensures you’re familiar with its behavior should a real alert arrive. Additionally, a warning history log keeps track of past alerts. For frequent travelers or those in seismic regions, this archive can be useful to verify whether alerts were issued (and potentially cross-reference with local seismic reports later).

Beyond alerts, Samsung’s system surfaces nearby emergency shelters, emergency contacts, and medical information. Users can predefine emergency contacts so that if an earthquake strikes, the system can display a quick-access option to call or message those contacts. Entering medical details—such as allergies, chronic conditions, or medications—means first responders (if they access the unlocked phone or if the user shares info) have critical health info instantly. The nearby shelters list draws from location data to guide users toward safer zones after an initial alert—especially valuable when outside familiar surroundings or in unfamiliar cities during travel.

Google’s Android Earthquake Alerts System is robust in that it aggregates seismic network data across devices to deliver warnings globally on supported handsets. It’s built into core Android services and has the advantage of consistency across brands and regions where Google services operate. However, Google’s implementation lacks user-facing customization beyond enabling/disabling alerts; there’s no built-in preview or sensitivity slider, nor integrated emergency contacts or medical info sections.

Some regions restrict Google’s system due to local regulations or service availability; Samsung’s custom solution could fill those gaps, especially in markets where Google’s alert infrastructure isn’t present or is region-locked. Rumors suggest Samsung’s system might initially target markets like China, where Google services are limited, akin to Samsung’s region-specific alternatives for other features.

Why build a parallel system? For Samsung, offering a richer, more customizable experience aligns with One UI’s ethos of personalization and added value. By integrating emergency resources directly into the alerts interface, Samsung positions its devices as not just smart but safety-conscious hubs. From a business perspective, differentiating One UI from stock Android fosters brand loyalty and gives Galaxy owners reasons to prefer Samsung devices.

Integrating emergency contacts and medical info raises privacy questions: how securely is that data stored? Samsung should clarify encryption practices and whether data remains on-device or syncs to cloud backups. Users must trust that sensitive health details are protected and only accessible when needed. Location access is inherent for alerts and nearby shelters; transparency on data usage, retention, and opt-in processes remains crucial. Given regulatory scrutiny around personal data, Samsung will need to ensure compliance across different markets.

As of mid-June 2025, this earthquake warnings module hasn’t appeared in public One UI 8.0 beta builds on the Galaxy S25 series, suggesting it’s still under internal testing or region-locked preview. Samsung may roll it out gradually, possibly starting in high-risk zones or markets lacking Google’s alert service. When it goes live, users should check Settings > Safety and emergency > Earthquake warnings for the new options. If your region doesn’t see it immediately, patience is key; Samsung often staggers feature launches based on model and location.

Samsung’s additions—custom thresholds, previews, integrated emergency resources—represent user-centric enhancements that other OEMs or Google itself might consider. The Android Earthquake Alerts System is open-source in parts; Google could incorporate threshold settings or preview functions in future OS updates. Meanwhile, third-party seismic apps already offer some of these features but lack system-level integration. If Samsung’s approach proves valuable in the field (e.g., faster responses or better user preparedness), it could spur wider adoption of richer alert features across Android.
