An analysis of the latest version v1.0.1387.1016999334 of the Android “Cross-Device Services” app, released on Tuesday, November 10, 2026, revealed newly discovered resource code related to the new scam protection feature “Scam Check.” The “Scam Check” anti-scam feature in “Cross-Device Services” is designed to display a notification reading “Unknown caller on your xxx” on another Android device registered to the same Google Account whenever an unknown number calls an Android device.
The “xxx” portion will be replaced by the name of the Android device that received the call. If the device name cannot be retrieved, it will display “Unknown caller on your phone.” However, the actual rollout of “Scam Check” has not yet been confirmed.

Once “Scam Check” is rolled out in “Cross-Device Services,” for example, even if a suspicious call comes in on an Android device that is charging in another room, you will be able to notice it on another Android device you are currently using nearby. Additionally, the scam detection for incoming calls is structured to be handled by features on the “Google Play services” side.
