Google DeepMind and Singapore’s Government Technology Agency (GovTech) are developing an AI model intended to detect scam patterns on Android devices and warn users before they share sensitive information or transfer money. Announced during Singapore International Cyber Week on October 14, 2026, the project is designed to analyze conversations on the device rather than send message content to the cloud. It is a development effort, not a confirmed Android feature with a published release date.

How the on-device scam detector is intended to work
The partners say they have fine-tuned Google’s lightweight Gemma model for scam detection using local scam conversations. The on-device approach is intended to identify signs of manipulation while keeping personal messages on the user’s device.

One report describes a two-stage process: a lightweight classifier screens messages, then a fine-tuned Gemma model examines more of a conversation when the first stage flags a possible threat. The device can then display a warning.
2 The reported goal is to intervene before a person shares credentials, other sensitive information or money—not to guarantee that every scam will be caught.

Some coverage names WhatsApp and Telegram as examples of messaging apps the system may analyze.
19 The available announcement materials do not establish the full list of supported apps or explain how the model will distinguish ordinary conversation from a scam in practice.
What the privacy claims do—and don’t—establish
The central privacy feature is local processing: the project is described as keeping message content on the device instead of transmitting it to cloud servers.

11 That design can allow analysis without sending chat text to a remote service, but the supplied materials do not detail a consent workflow or independently document every party’s access controls. They also do not provide measured alert-speed or detection-accuracy results.
The sources confirm fine-tuning on local scam conversations, but they do not establish the more specific claims that training combines anonymized reports, intelligence feeds and synthetic conversations, or explain how often the model will be updated as scam tactics change.

Availability and what remains unknown
Google DeepMind and GovTech have announced work to develop the model; the available sources do not give a public release date or confirm that it will be built into Android by default.

12 They also do not announce an international rollout. Adapting a model trained on local scam patterns for other markets may be possible, but no such deployment commitment is documented in the material available here.
The project responds to a serious problem: reports about the initiative put Singapore’s cumulative scam losses since 2019 at more than S$4 billion.
