As Cybersecurity Awareness Month closes, Google has released a detailed breakdown of Android’s anti-scam infrastructure, accompanied by independent evaluations and a commissioned survey designed to benchmark its protections against those found on iOS. The company claims its platform blocks more than 10 billion suspected malicious calls and messages monthly, and that a single month of ongoing RCS integrity checks stopped over 100 million suspicious numbers from accessing the messaging service entirely.

Survey Data and User Perception

A YouGov survey of 5,000 smartphone users across the United States, India, and Brazil found measurable differences in reported scam exposure between Android and iOS users. Key findings include:

  • Android users were 58% more likely than iOS users to report receiving zero scam texts in the prior week.
  • On Pixel devices specifically, users were 96% more likely than iPhone owners to report no scam texts.
  • iOS users were 65% more likely than Android users to report receiving three or more scam texts per week, a gap that widened to 136% when comparing iPhone directly against Pixel.
  • Android users were 20% more likely to rate their device’s scam protections as “very effective” or “extremely effective.”

Survey data commissioned by a vendor carries inherent limitations, and security professionals should weigh these figures accordingly. That said, the directional findings are consistent with the independent technical evaluations Google also cited.

Independent Technical Assessments

Counterpoint Research compared the latest Pixel, Samsung, Motorola, and iPhone devices across ten AI-powered protection categories, including email, browsing, and on-device behavioral protections. The firm found Android devices covered all ten categories with AI-driven features, while iOS covered only two.

Separately, cybersecurity firm Leviathan Security Group conducted a funded evaluation of scam and fraud protection across the iPhone 17, Moto Razr+ 2025, Pixel 10 Pro, and Samsung Galaxy Z Fold 7. Their analysis ranked the Pixel 10 Pro highest for default scam and fraud protection, citing call screening, scam detection, and real-time warning capabilities as primary differentiators. Both studies were funded or facilitated by Google, which is worth noting when interpreting results.

How the Protections Work

Google outlined the core mechanisms underpinning Android’s defenses:

  • Google Messages filtering: Analyzes sender reputation and message content to route suspected spam to a quarantine folder. An on-device AI model also scans for conversational scam patterns, such as pig-butchering schemes, and issues real-time warnings. Suspicious links in flagged messages are blocked.
  • Phone by Google call protection: Known spam calls are blocked before the phone rings. A Call Screen feature can intercept calls on the user’s behalf. On answered calls, on-device AI continues monitoring for suspicious conversational patterns. Call content is processed ephemerally and never leaves the device.
  • Social engineering countermeasures: Android blocks high-risk in-call actions such as installing untrusted apps or disabling security settings, and alerts users if screen sharing is active without their awareness.
  • Platform-level protections: Real-time app scanning via Google Play Protect and large-language-model-enhanced Safe Browsing in Chrome complement the messaging and call-layer defenses.

The broader context matters: mobile scam losses are estimated at over $400 billion globally in the past 12 months, driven in part by fraudsters adopting AI tools to generate more convincing lures. Platforms that can deploy equivalent AI countermeasures at scale, as Android appears to be doing here, represent a meaningful defensive advantage, provided the underlying detection models keep pace with attacker innovation.
