Samsung's One UI 7 Introduces AI-Powered Spam Blocking in South Korea

Samsung’s latest mobile software update, One UI 7, is bringing an innovative AI-powered spam blocking feature to Galaxy smartphones in South Korea. This new capability aims to combat the growing problem of illegal spam messages that often contain malicious content related to loans, gambling, and adult goods.

How the New AI Spam Blocker Works

The AI-powered spam blocking feature in One UI 7 uses advanced machine learning algorithms to automatically detect and filter out potentially harmful text messages. Here’s how it functions:

Step 1: The AI analyzes incoming text messages in real-time.

Step 2: It scans for suspicious patterns, keywords, and links commonly associated with illegal spam.

Step 3: Messages identified as potential spam are automatically blocked before reaching the user’s inbox.

Step 4: The system continually learns from new spam patterns to improve its accuracy over time.

This AI-driven approach provides a more dynamic and adaptive solution compared to traditional rule-based spam filters.

Collaboration with Korean Regulators

Samsung developed this feature in partnership with the Korea Internet Security Agency (KISA), a government body responsible for promoting cybersecurity and safe internet usage. This collaboration ensures that the spam blocking system aligns with local regulations and addresses specific concerns in the South Korean market.

The partnership with KISA is part of a broader initiative announced in late 2024 to combat the rising tide of illegal spam messages in South Korea. By combining efforts between technology companies and regulatory bodies, the goal is to create a more comprehensive defense against malicious actors.

Availability and Device Compatibility

Currently, the AI-powered spam blocking feature is available on the Galaxy S25 series devices in South Korea. Samsung has confirmed that it will extend support to other compatible Galaxy smartphones and tablets as they receive the One UI 7 update.

The global rollout of One UI 7 is scheduled to begin on April 7, 2025. However, it’s important to note that the availability of specific features may vary by region due to different regulatory environments and partnerships.

Potential for Global Expansion

While this particular implementation of AI-powered spam blocking is currently limited to South Korea, it represents a significant step forward in mobile security that could potentially be adapted for other markets. Samsung may develop similar features tailored to the specific spam and cybersecurity challenges faced in different countries.

The success of this feature in South Korea could serve as a model for collaboration between tech companies and regulatory bodies in other regions to address local digital security concerns.

Complementing Existing Security Measures

The new AI spam blocker in One UI 7 works in tandem with existing spam-filtering measures provided by mobile carriers in South Korea. This multi-layered approach creates a more robust defense against unwanted and potentially harmful messages.

For users, this means:

  • Reduced exposure to phishing attempts and scams
  • Less clutter in their message inboxes
  • Improved overall mobile security without requiring manual intervention

Privacy Considerations

Samsung has emphasized that the AI-powered spam blocking feature operates locally on the device, ensuring that message content is not sent to external servers for analysis. This approach helps maintain user privacy while still providing advanced protection against spam.


As mobile threats continue to evolve, features like Samsung’s AI-powered spam blocker showcase how smartphone software is adapting to provide users with smarter, more effective security tools. While currently limited to South Korea, this development signals a promising direction for mobile security worldwide.
