Google's Scam Detection Feature Poised for vivo Expansion, APK Teardown Suggests

Google's real-time scam detection system—designed to identify and warn users of potential voice-based fraud during incoming calls—may be expanding beyond its initial Pixel and Samsung Galaxy S26 deployments to include vivo smartphones, according to technical analysis published on August 17, 2026. The indication stems from a reverse-engineering examination of the latest Phone by Google app (version 234.0.9), which revealed embedded support logic and device-targeting flags specifically referencing vivo hardware.

What Is Google Scam Detection?

Previewed at Google I/O in May 2024 and launched as part of Google's broader Call Screen and Safety Check suite, Scam Detection uses on-device machine learning models to analyze audio patterns, caller behavior, and metadata—including call timing, repetition frequency, and speech cadence—in real time. When suspicious indicators align with known scam profiles (e.g., impersonation of government agencies, tech support, or financial institutions), the system displays an on-screen warning before or during the call and optionally reads a verbal alert.

The feature operates entirely on-device: no call audio is uploaded to Google servers. It relies on the Google Play Services security module and requires Android 13 or higher, along with Google Mobile Services (GMS) certification. As of August 2026, it remains opt-in and disabled by default—even on supported devices.

Confirmed Expansion Path: From Pixel to Samsung to vivo

Scam Detection debuted exclusively on Google Pixel phones with the March 2024 Pixel Feature Drop. In early 2026, Google announced official support for Samsung Galaxy S26 series devices, with independent verification from Android Authority and Android Police confirming the feature on Galaxy S26 Ultra units running One UI 7.0 and Android 16.

The vivo expansion was first indicated by Android Authority on August 17, 2026, based on an APK teardown conducted in collaboration with mobile analyst AssembleDebug. The analysis identified internal configuration references within the Phone by Google app that include vivo among supported manufacturers for scam detection capabilities, alongside existing entries for Google and Samsung. Crucially, the configuration structure appears to reference ro.product.manufacturer identifiers that explicitly include "vivo" alongside "google" and "samsung".

Technical Verification and Limitations

To validate the Android Authority report, our team independently examined the publicly available Phone by Google APK (version 234.0.9) from the official Google Play Store archive (via APKMirror, timestamped August 2026). We confirmed:

• The presence of vivo within scam detection manufacturer configuration arrays in the application's resource files.
• Conditional support structures that would enable the feature on devices identifying as vivo-manufactured hardware.
• Resource file entries tied to scam detection UI components that reference vivo alongside other supported OEMs.

However, no functional activation has yet been observed on live vivo devices. As of August 18, 2026, the feature remains inactive on all tested vivo models—including recent flagship and mid-range devices running Android 16 with updated GMS and Play Services security patches. This confirms the implementation is preliminary and staged, not yet enabled server-side or rolled out to end users.

Why vivo? Strategic Context and Market Alignment

vivo's inclusion reflects Google's prioritization of OEM partners with high-volume global distribution, strong GMS compliance, and shared investment in on-device AI safety infrastructure. According to preliminary data from Counterpoint Research's Q2 2026 Global Smartphone Tracker, vivo ranked fifth globally in shipments with an 8% market share, with particularly strong penetration in India, Southeast Asia, and parts of Africa. These regions represent high-priority markets for telecom fraud prevention, per industry security reports.

Notably, vivo has co-developed on-device AI capabilities with Google since 2023—including localized language models for regional languages—and maintains deep GMS integration across its global product lines. This technical alignment likely accelerated integration timelines relative to other OEMs.

What's Not Confirmed — And What's Still Rumored

While the Phone by Google APK evidence is indicative, several claims circulating online remain unverified:

• No official announcement: Neither Google nor vivo has issued a press release, blog post, or social media statement confirming the rollout. Google has not commented publicly on the timeline or scope of the expansion.
• No device-specific timeline: While speculation suggests vivo's latest flagship series may be first in line, no model-level targeting has been confirmed in the APK. The configuration applies broadly to ro.product.manufacturer == "vivo", meaning eligibility depends on software update cadence—not hardware generation.
• No carrier dependency: Unlike earlier versions of Call Screen, Scam Detection does not require carrier provisioning. It functions over VoLTE, VoNR, and Wi-Fi Calling—confirmed via testing on major networks in the United States, India, and Southeast Asia.

Comparison: Scam Detection Support Across Android OEMs (as of August 2026)

OEM	First Supported Device	Android Version Required	Status	Rollout Method
Google	Pixel 8 Pro	Android 14	Live (since March 2024)	Feature Drop
Samsung	Galaxy S26 Ultra	Android 16	Live (since early 2026)	One UI 7.0 update
vivo	TBD (all GMS-certified models)	Android 16 (projected)	Staged (APK present, not active)	Future OTA via Phone app

FAQ

• Is Scam Detection already working on vivo phones?

  No. While the underlying code and resources are present in the latest Phone by Google app, the feature remains disabled on all tested vivo devices as of August 18, 2026. Activation requires both a server-side flag and a subsequent software update from vivo.

• Does Scam Detection work without Google services?

  No. The feature requires Google Play Services, Android 16, and a GMS-certified device. It is unavailable on devices using Huawei Mobile Services, alternative regional service frameworks, or custom ROMs lacking GMS.

• Will Scam Detection come to OnePlus, Xiaomi, or OPPO?

  There is no evidence in current APKs or official documentation supporting imminent rollout to those brands. The Phone by Google app v234.0.9 contains no confirmed references to oneplus, xiaomi, or oppo in scam detection configuration arrays. Future inclusion would require separate engineering collaboration and certification.
