Google is bolstering Android's call fraud protection capabilities via Google Play Services, aiming to shield users from scams during calls that involve financial or payment - related apps. Here are the specific measures:

• To thwart malware intrusion, users will be barred from disabling Google Play Protect while on calls. This ensures that the built - in security feature remains active to detect and prevent malicious software.
• During calls, users won't be allowed to enable sideloaded apps or grant auxiliary service permissions. This step is crucial to prevent malicious apps from taking control of devices, as sideloaded apps may not have undergone the same rigorous security checks as those from the official Google Play Store.
• Screen - sharing warnings have been introduced. If a user attempts to share banking apps with strangers during a call, a warning will pop up, and they'll have a one - click option to end the call. This is to prevent potential financial fraud as sharing sensitive financial information with unknown parties can be extremely risky.

This new feature has undergone testing in collaboration with several UK banks. It is applicable to Android 11 and later versions and is being gradually rolled out in the United States, India, and Brazil.

In addition to these call - related protections, the Messages app has expanded the scope of its AI algorithms to identify a wider range of fraudulent behaviors. Meanwhile, the Contacts app is set to introduce a Key Verifier feature soon. This feature will use public encryption keys to verify identities, effectively preventing contact impersonation fraud, where scammers pretend to be someone the user knows to carry out fraudulent activities.
