Google Messages begins rolling out opt-in cloud checks for complex scams

Google Messages has begun rolling out an optional Enhanced protection mode that can use cloud Gemini models to examine suspected scams in conversations with unknown senders. Google announced the setting on 14 October, and a 23 October report documented its appearance in the Messages beta. Availability is still dependent on the app version and supported device.[1][4]

Google wants the larger models to recognise manipulation developing across an exchange, adding context beyond its existing on-device detection. Remote analysis will use Private AI Compute. The setting also strengthens unfamiliar-link checks with Gemini Nano and web signals.[1]

Introduced in November 2025, Private AI Compute combines encryption, remote attestation and hardware-protected cloud processing. Google says personal data within this environment is inaccessible to anyone else, including the company. It is a design intended to let a phone draw on more computing power while restricting access to the information being processed.[2]

Existing spam protection already combines phone and server checks. Google’s help page describes local pattern detection, uploading URLs for malicious-link checks, and possible brief processing of unencrypted message content. A separate, optional spam report can also send information to Google. The data handling depends on the feature being used.[3]

Check the feature as well as the phone

Google lists cloud enhancement on devices including Pixel 6 and newer, Galaxy S24 models and newer, and other Android AICore devices. The Nano link enhancement has a newer hardware list, including Pixel 10 and Galaxy S26. These are different eligibility lists within the same announced setting.[1]

Google’s current help page describes three settings under Messages settings → Protection & Safety → Spam and scam protection: Enhanced protection, Standard protection and No protection. Standard protection is the default where available. The enhanced option may not yet be present on every phone or app version, and the cloud-analysis and on-device link-check features have different device eligibility.[3][4]
