Google announced on Tuesday the launch of a fake call detection feature on Android.The system identifies scam attempts that use voices cloned by artificial intelligence to imitate family members or trusted contacts. The functionality begins to be distributed globally this month via the Google app Telefone.
The measure responds to the evolution of scammers’ tactics. Depois users began ignoring unknown numbers, criminals began spoofing saved contact identifiers and employing AI to reproduce voices in high fidelity. A classic example involves a caller that appears as “Mom” and sounds identical, asking for money for a made-up emergency. The feature operates automatically and aims to stop the scam before the user responds.
Silent Verificação uses RCS protocol
The mechanism works like a digital handshake between devices. Quando a contact calls using the Telefone app from Google, the device sends a silent confirmation signal via Rich Communication Services. The receiving phone verifies that the call actually comes from the contact’s registered device.
Caso signal is absent, the system consults the real device. If the original device responds that it is not making any calls, the app displays an immediate alert on the screen. The guideline is to disconnect the connection immediately. Todo process takes place in the background, without requiring user action.
Essa approach takes advantage of RCS, an open protocol that allows adoption by other applications and operators. Google highlighted that the technology was built to be scalable. Dispositivos with Android 12 or higher receive the feature, with initial rollout on Pixels.
- Automatic Detecção enabled by default
- Funcionamento in the background without intervention
- Silent Validação via RCS between compatible devices
- Alerta instant visual in case of suspicion
- Compatibilidade with Android 12 or newer
- Exige app Telefone, Contatos and Mensagens from Google installed
Outros AI features arrive with the update
Fake call detection is part of this month’s Android news package. The Google Fotos gains the “wardrobe”, a tool that catalogs clothes present in the library’s images. Usuários can browse the pieces and try out virtual combinations. Release begins next week for eligible users on Estados Unidos, Índia and Brasil on devices with Android 10 or higher.
Google Play Livros receives “Catch me up”. The feature offers a summary to resume reading and allows you to highlight excerpts or ask questions about the content. The new feature is now available for selected titles in English starting this Tuesday.
Já o Circle to Search now allows you to search for a complete set of clothes at once. Antes it was necessary to research each part separately. The update is valid for all devices with Android 14 or higher that have the feature activated.
Como feature changes scam protection
The new development represents a significant advance in combating fraud that exploits emotional trust. Golpistas increasingly invests in affordable AI tools to clone voices in a few seconds. Relatos of global financial losses from this type of scam exceed hundreds of billions of dollars annually.
The system focuses on checking the source device instead of just analyzing audio. Isso reduces the scope for manipulation by deepfakes. Especialistas in digital security evaluate the initiative as a practical step that transfers part of the detection responsibility to the operating system itself.
Usuários must have the three Google applications installed and configured as default. On many devices, especially Pixels and Motorolas, they are already pre-installed. The Samsung has also migrated to the Google messaging ecosystem in recent models.
Disponibilidade and technical requirements
The rollout occurs gradually across the world. Pixels receive the update first, followed by other manufacturers who join the Telefone app from Google. Não requires an operating system update beyond Android 12.
The feature depends on data connection for the RCS handshake. In areas with weak signal, scanning may be delayed or temporarily fail. Google recommends keeping applications updated to ensure best performance.
Fabricantes and calling app developers may adopt the open protocol in the future. Isso would extend protection to users who do not use the default Google app.
Impacto expected for Brazilian users
No Brasil, where telephone scams represent a recurring problem, the tool arrives at an opportune time. Autoridades register an increase in frauds that simulate family members or financial institutions. Visual alerting can help stop conversations before the user provides data or sends money.
Functionality does not replace basic caution. Especialistas continues to recommend checking information through official channels despite the alert. The feature adds an extra layer of protection without eliminating the need for common sense.
Telephony Empresas and regulatory bodies are observing the initiative with interest. Caso the RCS standard is consolidated, it can influence solutions on a national scale. For now, protection depends on the adoption of Google apps.
Google emphasizes that the focus remains on privacy. Verification signals are encrypted and do not store call content. The company plans to expand detection capabilities in future updates based on user feedback.
