Android 16 enhances user security with AI scam detection and call controls

Despite privacy concerns about real-time call analysis, Google assures all data stays on-device with no storage or sharing, giving users full control to enable or disable the feature, while enhancing protection against sophisticated phone scams

Google has rolled out a suite of new security enhancements for Android 16 aimed at preventing phone call-related scams, signalling a stronger push toward user safety and real-time fraud protection. The new features were unveiled during The Android Show: I/O Edition on May 13, and are designed to prevent common scam tactics that involve tricking users into giving up control of their devices during phone conversations.

A key addition in Android 16 is a restriction on certain high-risk actions while a user is on a call with someone not saved in their contacts. During such calls, Android will now block first-time sideloading of apps via browsers, messaging platforms, or file-sharing services. It will also prevent users from granting accessibility permissions to apps—often a tactic scammers use to gain control over devices. Instead, a warning will appear on-screen: “This setting is blocked to protect your device.”

New anti-scam call features

In an experimental move, Google is also trialing an anti-scam feature in the UK, targeting screen-sharing scams. If a user attempts to open select banking apps—such as Monzo, NatWest, or Revolut—while sharing their screen during a call, Android issues a warning about a “likely scam.” Users are then prompted to either end the call or wait 30 seconds before proceeding. This delay is meant to provide users a moment to reconsider and recognize potential threats before exposing sensitive financial information.

Google is also expanding its on-device artificial intelligence capabilities to detect potential scams during active calls. Without recording or storing audio, the AI analyzes conversations in real time for red flags—such as requests for money transfers or sensitive data. If suspicious activity is detected, users receive visual, audio, and haptic alerts urging them to end the call.

Enhanced message scam protection

Additionally, the Messages app is receiving an AI-powered upgrade. Built-in scam detection will scan SMS, MMS, and RCS messages from unknown numbers for fraudulent content. Users will then have the option to ignore, block, or report the sender. All detection happens directly on the device to ensure privacy, and users can opt out if they choose.

While privacy advocates have raised concerns about real-time call analysis, Google asserts that all data remains local to the device and that no content is stored or shared. Users retain full control over whether to activate or disable the feature.

With these updates, Google is placing greater emphasis on safeguarding Android users from increasingly sophisticated scams, particularly those involving real-time deception during phone calls.
