Executive Summary
Google is expanding its AI anti-fraud push in India, rolling out on-device real-time call scam detection for Pixel 9 and launching screen-sharing scam alerts in a pilot with Navi, Paytm and Google Pay on Android 11+. This matters because it moves detection closer to the edge-where scams happen-reducing data exposure and latency. But language (English-only) and device (Pixel 9+) limits mean the immediate coverage is narrow in a market where Android is dominant but Pixel share is under 1%.
Key Takeaways
- Short-term impact is constrained: call detection runs only on Pixel 9+ and in English; alerts apply to unknown numbers and are off by default.
- Screen-sharing alerts have broader reach (Android 11+), with a clear user escape hatch (one-tap to end call/stop sharing) and Indian language support planned.
- Privacy posture is strong: Gemini Nano analyzes calls on-device, with no audio uploaded; a periodic beep during the call signals analysis to participants.
- Play Protect enforcement is scaling: over 115 million blocked installation attempts of risky sideloaded apps this year; Google Pay surfaces 1+ million weekly fraud warnings.
- Ecosystem risk remains: fake or predatory apps still slip through reviews, highlighting the limits of marketplace policing.
Breaking Down the Announcement
Google’s real-time scam detection listens to ongoing calls and uses Gemini Nano on-device to spot social engineering patterns (e.g., demands for OTPs, PINs, or urgent transfers). It does not record or send audio to Google’s servers. The feature is off by default, applies only to unknown numbers, and inserts a beep during the conversation to notify both parties. It launched in the U.S. in March and is now expanding to India, but initially only on Pixel 9 and later models and only in English-warnings are English-only too. Google says support for non-Pixel Android phones is planned without a timeline.
Separately, screen-sharing alerts—first previewed at Google I/O—are piloting in India with Navi, Paytm, and Google Pay. On Android 11+, users will see prompts if they are screen-sharing while on a call, with a one-tap control to end the call and stop sharing. Google expects to add more app partners and will localize alerts into Indian languages, though specifics are pending.
Industry Context
India’s fraud problem is acute and rising. The Reserve Bank of India reports that frauds involving digital transactions made up more than half of reported bank fraud in 2024—13,516 cases with ₹5.2 billion ($58.6 million) in losses. The Ministry of Home Affairs estimates ₹70 billion ($789 million) lost to online scams in the first five months of 2025 alone, and many incidents go unreported. Android powers roughly 96% of smartphones in India, yet Pixel held under 1% share in 2024, and most users rely on non-English languages. That mismatch is the core adoption challenge.
What This Changes for Operators
On-device detection matters because it reduces latency and preserves privacy while providing context beyond number reputation lists. For BFSI and fintech teams, the screen-sharing alerts can directly blunt a common fraud path: social engineers walking victims through screen-share to capture OTPs and PINs. The one-tap interrupt lowers friction for the user to exit a risky flow. Combined with Play Protect’s pressure on predatory app sideloading and Google Pay’s weekly warning volume, this signals a platform-level shift toward proactive tripwires at the moment of risk.
that said, the call-detection feature’s default-off setting and Pixel-only, English-only scope sharply limit immediate benefit. Enterprises should assume near-term protection gains will come primarily from the screen-sharing alerts in partner apps and from continued marketplace enforcement—not from universal call screening across their user base.
Risks and Constraints
- Coverage gap: With Pixel under 1% share, most Indian users won’t get on-device call detection at launch; non-Pixel rollout lacks a timeline.
- Language gap: English-only detection and warnings miss the majority of users who operate in Indian languages, limiting efficacy.
- User control: Feature is opt-in and limited to unknown numbers, dampening activation and leaving room for targeted scams from known or spoofed contacts.
- False positives/negatives: Enterprises should expect calibration issues in early phases; overzealous prompts can add friction and drop-offs in legitimate service flows.
- Ecosystem loopholes: Despite stronger Play Protect, malicious apps have historically passed review until external reports force takedowns.
Competitive and Ecosystem Angle
Third-party services like Truecaller and OEM dialers already flag spam based on number reputation and user reports. Google’s new approach adds conversational analysis, which can detect intent even when number reputation is clean—an advantage when fraudsters frequently switch numbers. Compared with pure cloud screening, on-device LLM inference reduces data transfer risks and can run even with limited connectivity. The screen-sharing alerts leverage OS-level cues, creating a stronger safety net than app-level heuristics alone.
Operator’s Playbook: What to Do Now
- Join or prepare for the screen-sharing pilot: BFSI, lending, and wallet apps should engage Google to participate. Instrument funnels to measure alert-triggered drop-offs, recovery rates, and fraud loss deltas.
- Localize user education: Until call detection supports Indian languages broadly, push in-app and SMS education in users’ primary languages on screen-share risks, OTP/PIN hygiene, and safe support channels.
- Harden verification flows: Reduce reliance on OTP during live calls and add rate-limits, out-of-band confirmations, and contextual risk scoring for high-value actions.
- Tune for friction: Set up A/B tests where alerts appear, record opt-out and escalation paths, and train support agents to handle alert-driven call terminations without losing legitimate customers.
- Audit app permissions and distribution: Use Play Protect guidance to strip sensitive permissions, block sideload pathways for your app, and routinely test against predatory loan-app impersonators.
Looking Ahead
If Google moves call scam detection beyond Pixel and expands language coverage, the protective surface area could scale quickly across India’s Android base. Until then, expect the most tangible wins from OS-integrated screen-sharing alerts and ongoing marketplace enforcement. Enterprises should treat this as a step-change in the platform’s safety tooling—useful, privacy-preserving, but not yet ubiquitous—and plan controls and education accordingly.
