Android 17 Takes Aim at Scam Calls and Phone Theft

Google has announced a series of Android security and privacy upgrades designed to protect users from scam calls, malicious apps, phone theft and unnecessary data sharing.

Many of the biggest changes are expected with Android 17, coming later this year, although some protections will also work on older versions of Android.

Fake bank calls

One major update targets spoofed financial calls. These are scams where criminals make a call look as if it is coming from a real bank.

Android will try to verify calls from participating financial institutions in the background. If the bank cannot confirm the call is genuine, the phone can automatically end it before the user answers or shares sensitive information.

The feature will initially support Android 11 and newer devices with participating banks including Revolut, Itaú and Nubank. Google is expected to expand support to more banks later.

Suspicious app behaviour

Google is also improving Live Threat Detection, which watches for risky app behaviour after an app has been installed.

The system will look for warning signs such as SMS forwarding, hidden app icons, background launching and misuse of accessibility permissions. These behaviours can be linked to malware, stalkerware or attempts to steal one-time passcodes.

Chrome on Android will also check downloaded APK files for known malware, helping warn users before risky apps are installed outside the Play Store.

Stolen phone protection

Android 17 will make stolen phones harder to access. The “Mark as lost” feature will support biometric checks, so a stolen PIN or passcode alone may not be enough for a thief to regain access.

When a phone is marked as lost, Android can hide Quick Settings, block new Wi-Fi and Bluetooth connections, and make passcode guessing harder on supported devices.

Google is also turning on features such as Remote Lock and Theft Detection Lock by default on new Android 17 devices, and on devices that are reset or upgraded.

Better privacy controls

Android 17 will give users more control over what they share with apps.

Users will be able to share precise location temporarily while an app is open, rather than granting longer-term access. Once the app is closed, precise location sharing turns off.

Apps will also be able to request access to selected contacts or specific contact details instead of asking for the entire address book.

Checking Android is genuine

Google is adding Android OS verification, starting with Pixel devices. This is designed to help confirm that a phone is running a legitimate version of Android, rather than a modified version that could put user data at risk.

Other planned protections include hiding one-time passcodes from most apps for a short period, stronger Advanced Protection settings and intrusion logging on newer Android versions.

Together, the updates show Google is trying to make Android security more automatic, especially against scams that rely on speed, confusion and stolen personal data.
