Google’s modern Pixel phones offer a Scam Detection feature that may soon expand to monitor outgoing calls, according to a recent beta version of the Phone by Google app. The on-device AI tool, which currently protects users exclusively during incoming calls, runs locally on Pixel 9 and newer devices using Gemini technology to flag suspicious audio patterns without sending conversation data to Google.
How Google’s Scam Detection Works on Pixel Phones
The Scam Detection tool monitors phone call audio for clues that the person on the other end may be a scammer. According to Google documentation, the software operates entirely on-device. Neither call audio nor transcripts are shared with Google. Users must manually opt in to use the feature. On Pixel 9 and newer, the processing is powered by Gemini.
Pro Tip: You can check your Phone by Google app settings to see if Scam Detection is available on your device, keeping in mind that the feature requires users to manually opt in.
Evidence Points to Outgoing Call Monitoring
An APK teardown of a recent beta version of the Phone by Google app revealed new code indicating potential expansion. A flag was spotted within the application package:
enableSharpieOnOutgoingCalls
“Sharpie” serves as Google’s internal codename for the Scam Detection feature. While developers have not yet been able to activate the setting in live environments, the code indicates active engineering work to cover user-initiated calls. Perpetrators frequently use outbound calling techniques to bypass inbound filters. Enabling the tool for outgoing calls closes that security gap.
Did You Know? An APK teardown helps predict features that may arrive on a service in the future based on work-in-progress code. However, it is possible that such predicted features may not make it to a public release.
