The update is an essential part of Samsung’s update strategy, focusing on long-term device reliability rather than just adding new features. Since the Galaxy Watch 8 lineup and the all-new Galaxy Watch Ultra are Samsung’s most premium wearable offerings in 2025, it’s no surprise that Samsung is prioritizing their maintenance with frequent updates.

What’s Included in the Update

Unlike major updates that introduce new features, fitness tracking modes, or UI changes, this update is centered around security and performance improvements.

Here’s a breakdown of what it includes:

August 2025 Security Patch:
Strengthens the watch’s defense against potential vulnerabilities and malware.
Bug Fixes & Stability Enhancements:
While not explicitly mentioned in the changelog, these updates typically include minor optimizations that make the software more reliable.
Runs on One UI 8 Watch:

This update might feel small on paper, but it is crucial for maintaining smooth day-to-day performance.

Update Details

The rollout is happening in phases, beginning in South Korea and expanding globally over the coming weeks. Samsung follows this regional rollout strategy to ensure stability before a worldwide release.

Here are the specific details:

Device	Software Version	Download Size	Notes
Galaxy Watch Ultra (2025)	BYH6	~164 MB	Security patch & stability
Galaxy Watch 8 Series	AYH7	~163 MB	Security patch & bug fixes

Even though the download size is relatively small, it plays a significant role in enhancing the watch’s long-term usability.

Why Security Updates Matter for Smartwatches

Many users may wonder why a security patch update is important for a smartwatch. Unlike smartphones, which directly handle sensitive apps, payments, and personal data, smartwatches may seem less critical. However, modern smartwatches like the Galaxy Watch 8 and Watch Ultra are deeply integrated with smartphones, meaning they often share:

Health & Fitness Data (heart rate, sleep tracking, blood oxygen, workouts)
Payment Information (Samsung Pay, Google Wallet)
Personal Notifications (calls, texts, app alerts)

Without regular updates, vulnerabilities could expose this sensitive data. That’s why Samsung is consistent in delivering security patches even to its wearable devices.

How to Get the Update

If you own a Galaxy Watch 8 series or Galaxy Watch Ultra, you can manually check for the update. Here’s how:

Open the Samsung Health app on your connected Android smartphone.
Navigate to the Watch Settings.
Select Watch Software Update.
Tap on Download and Install if the update is available.
Ensure your watch is connected to Wi-Fi and has at least 50% battery before updating.

Pro Tip: Keep your Samsung Health app updated to the latest version for a smooth update experience.

Rollout Timeline

Currently, the update has started in South Korea – Samsung’s home market. Traditionally, updates expand to:

Asia-Pacific regions (India, Japan, Vietnam, etc.)
European markets
North & South America

Based on previous rollout timelines, most global users can expect the update within 1–3 weeks.

One UI 8 Watch – The Software Platform

Both the Galaxy Watch 8 series and the Galaxy Watch Ultra (2025) run on One UI 8 Watch, Samsung’s latest smartwatch software layer. Built on Google’s Wear OS, it integrates Samsung-exclusive features such as:

Advanced Samsung Health features
Galaxy AI enhancements for workouts and sleep tracking
Better battery optimization
Seamless Galaxy ecosystem connectivity (phones, tablets, Galaxy Buds, and SmartThings)

Even though this update is security-focused, it ensures that One UI 8 Watch remains secure and stable across devices.

Galaxy Watch Ultra (2025) – The New Flagship

The Galaxy Watch Ultra is Samsung’s new rugged, premium smartwatch designed to rival the Apple Watch Ultra lineup. With features like:

Larger display with sapphire glass protection
Extreme durability (water, dust, shock resistance)
Advanced sports tracking & GPS
Extended battery life

… it has quickly become a favorite among fitness enthusiasts and adventure seekers.

Receiving frequent updates like the August 2025 patch ensures that this new flagship remains reliable during intense outdoor activities and professional use.

Galaxy Watch 8 Series – The All-Rounder

The Galaxy Watch 8 series builds on Samsung’s successful wearable legacy. Available in different sizes and styles, it is a versatile smartwatch for daily users. Key highlights include:

Improved health sensors (ECG, skin temperature, stress tracking)
Customizable design with multiple strap options
AI-powered insights for workouts and sleep
Smooth performance with new processors

This August 2025 update strengthens the series’ software reliability, making sure it stays fast, safe, and future-ready.

Should You Install the Update Immediately?

Yes – absolutely. While some users may prefer to wait, security patches are essential. Here’s why you should update:

Protects against vulnerabilities
Optimizes background processes
Prepares your watch for future updates
Improves compatibility with the latest apps

Since the download is lightweight (under 200MB), it won’t take long, and your watch will benefit instantly.

Samsung’s Commitment to Software Updates

Over the years, Samsung has significantly improved its software support. While older watches like the Galaxy Watch 4 series received updates for 3 years, the Watch 8 and Watch Ultra are expected to get 5 years of support – matching Samsung’s smartphone policy.

This strategy ensures that Samsung remains competitive against Apple, where long-term updates have been a major advantage.

Final Thoughts

The August 2025 security update for the Galaxy Watch 8 series and Galaxy Watch Ultra may not be the most exciting update in terms of features, but it is essential for performance, security, and stability. With software versions AYH7 (Watch 8) and BYH6 (Watch Ultra), this rollout ensures that Samsung’s premium watches remain in top shape.

If you’re in Korea, you can update right away. For global users, it’s just a matter of time before the notification pops up. Keeping your smartwatch updated is the best way to ensure it runs smoothly and securely for years to come.
