Smartphone Features to Block Spam Calls
Monthly investigations show hundreds of thousands of spam calls; Clever Dialer recorded more than 585,000 spam calls in April 2026. Smartphone vendors and third-party apps offer multiple protections: Google is rolling out an Android feature that verifies incoming calls from supported banks by communicating with the device's installed banking app to detect spoofing (initial partners: Revolut, Itaú, Nubank). Samsung devices include a "Smart Call" feature that flags and lets users block or report suspicious numbers. Pixel phones offer a Call Screen / Call Filter assistant that can answer and transcribe suspicious calls; in the US this can be automatic, while in Germany it is manually enabled. Apple provides call identification, an Anruffilter (call filter) assistant and options to silence unknown numbers. Third‑party apps mentioned include Clever Dialer and Tellows, which rely on community reports to mark spam numbers.
A major platform (Google/Android) is rolling out a technical feature that changes how the OS verifies and handles incoming calls from banks, requiring bank partnerships and impacting device-level security and app integrations.

Phone and App Features to Defend Against Spyware
Targeted spyware attacks — including zero-click exploits used against journalists and civil‑society members — have become common. Major platform owners now offer opt‑in defenses to reduce the risk of these stealthy hacks: Apple’s Lockdown Mode, Google’s Advanced Protection Program (and Android’s Advanced Protection Mode), and WhatsApp’s Strict Account Settings. These features trade some convenience for stronger protections (blocking certain message attachments, restricting links, tightening app install policies, blocking legacy networks, requiring security keys, enabling intrusion logging, etc.). Security researchers and publishers recommend enabling these controls if you are at risk from government‑grade surveillance. While not foolproof, evidence and forensic analyses indicate these measures have helped stop or limit successful spyware compromises in real cases.
Google adds AI scam-call warning to Android Phone app
Google has introduced a new AI-based scam-call warning in its Android Phone app to help users detect calls that use AI-generated voices to impersonate contacts. The feature, available free via Google Play and automatically active for users of the Google Phone app, exchanges encrypted real-time data between devices to verify whether the displayed caller is the genuine contact; if verification fails the app pings the alleged contact's device and, based on the response, warns the recipient, reports and blocks the number. The rollout begins this month on Pixel phones and will expand to other Android devices running Android 12 or later. Google built the system on the RCS standard so other companies can implement the same verification in other calling apps.
Google launches fake-call detection to block AI deepfakes
Google announced a new fake call detection feature for Android that aims to protect users from AI voice deepfake impersonation scams. Rolling out globally this month in the Phone by Google app for Android 12+ devices (starting with Pixel phones), the feature is enabled by default and runs automatically. It uses a silent confirmation signal — described as a “digital handshake” built on Rich Communication Services (RCS) — between devices when both caller and recipient use Phone by Google; missing confirmation triggers a verification ping to the caller’s device and, if the real device confirms no call is in progress, the recipient sees a warning to hang up. The announcement was published June 2, 2026, alongside other Android updates such as Google Photos’ wardrobe feature and Play Books’ recap tools.
