Ten Samsung Galaxy flagship models began receiving Google's June 2026 Android Feature Drop yesterday, bringing three of the quarter's most significant changes — fake call detection, expanded Quick Share interoperability with AirDrop, and a Gemini-powered wardrobe tool in Google Photos — to millions of users who had been waiting behind Pixel owners since the rollout began on June 2. The broader OEM deployment confirms that the most meaningful security upgrade in the drop, a new RCS-based phone verification system designed to catch AI voice-cloning scams before a call is answered, is now moving beyond Google's own hardware.

The update lands as INTERPOL's March 2026 Global Financial Fraud Threat Assessment linked impersonation fraud — the specific threat fake call detection targets — to an estimated $442 billion in global losses last year.

Fake Call Detection Uses RCS, Not Audio Analysis

The feature Google describes as an industry first does not listen to what a caller says. It instead performs a silent, end-to-end encrypted cryptographic handshake using RCS — Rich Communication Services, the GSMA-developed protocol that has replaced SMS messaging on most modern Android devices — to verify whether an incoming call actually originates from the physical hardware of the person whose number appears on screen.

When a saved contact places a call, their Phone by Google app sends a silent confirmation token over the RCS network to the recipient's device in real time. If that token is absent — as it would be when a scammer routes a call through VoIP software that spoofs a contact's number — the recipient's phone pings the contact's real device directly. If that device confirms no call is in progress, an on-screen warning appears advising the user to hang up immediately. Google's Security Blog confirmed these details when the feature was announced on June 2, 2026.

The distinction from Google's earlier Gemini Nano scam detection feature matters technically. The Gemini approach analyzes audio patterns during a live call to identify suspicious language. The RCS handshake does not touch the audio at all — it verifies device identity before the call progresses, an approach that cannot be fooled by a convincing voice clone because it never evaluates the voice.

There is a structural limitation: both the caller and recipient must be running Phone by Google with Google Contacts, Google Messages, and an active RCS connection. The feature does not protect against spoofed calls from contacts who use a different dialer app, who have RCS disabled, or who call from an iPhone. Google built the feature on the open RCS standard specifically to allow other phone application developers and device manufacturers to adopt the same verification mechanism, which would expand its protective reach over time.

The feature is enabled by default on any Android 12 or later device running Phone by Google as the default dialer. Devices running Android 11 or earlier are not eligible.

Why STIR/SHAKEN Was Not Enough

The network-level call authentication framework the FCC mandated in 2021 — known as STIR/SHAKEN — authenticates carrier routing but does not address the specific attack fake call detection is designed to stop. Margot Saunders, senior counsel at the National Consumer Law Center, noted this year that the framework fails to ensure accurate caller ID because voice service providers can rent thousands of phone numbers to telemarketers and scammers that technically comply with STIR/SHAKEN while still routing fraudulent calls.

Google's device-layer approach works at a different level. Rather than validating the routing chain between carriers, it asks whether the specific phone hardware registered to the contact is actually participating in the call. A spoofed number that travels correctly through every carrier authentication step still fails this check, because the spoof has no access to the cryptographic token that only the real device can send.

Quick Share AirDrop Expands to Samsung, OnePlus, and More

The June drop also completes a year-long expansion of Quick Share's interoperability with Apple AirDrop. BGR reported that users on supported Samsung Galaxy S24 and S25 series devices, OnePlus 15, Xiaomi 17T Pro, Vivo X300 and X300 Pro, and Honor Magic V6 can now send and receive files directly with iPhone, iPad, and macOS users through the Quick Share interface, without installing a third-party app. The iPhone or iPad user must set their AirDrop to "Everyone" for 10 minutes to initiate a transfer.

Quick Share uses proximity-based Bluetooth and Wi-Fi to transfer files without requiring an internet connection, which gives it a practical speed and privacy advantage over cloud-based alternatives for nearby transfers. The cross-platform functionality was first introduced on Pixel 10 devices in November 2025 and has expanded to supported hardware through successive drops.

Google Photos Wardrobe Begins Rolling Out This Week

Google Photos is gaining a Gemini-powered Wardrobe feature that reads clothing photos already stored in a user's library and generates outfit combination suggestions. BGR reported the rollout is expected to begin mid-June 2026, meaning eligible devices may begin receiving it this week.

The feature requires no new photography — it draws from clothing items already in the library — and generates suggestions based on the items it can identify. Google described it as a way to address the common friction of not knowing how to combine items already in a wardrobe before getting dressed.

Google Play Books Gains a "Catch Me Up" Recap Tool

Google Play Books is adding a Book Insights panel powered by Gemini. When zoomed out from a page, a light bulb icon appears in the top right corner of the reading view. Tapping it opens a chat interface where users can tap "Catch me up" for a condensed recap of what they have read so far, or highlight any passage to ask questions about characters, themes, or context.

The feature launches for select English titles initially. SlashGear noted that the implementation appears more open-ended than Amazon Kindle's comparable recap tools, functioning more like a contextual chatbot than a structured summary interface.

Circle to Search Gets In-App Refinements

Circle to Search — Google's gesture-based visual search tool, which lets users draw a circle around any object on screen to initiate a search — receives accuracy and relevance improvements for searches initiated within third-party applications. The update also extends to outfit identification: users can now circle an entire outfit at once and receive a detailed breakdown of individual items from hat to footwear, rather than identifying one item at a time.

What Google Is Building Toward

The five features share a structural logic. Rather than asking Android users to adopt a new application or habit, Google is embedding AI-driven capabilities into the surfaces of tools they already use: the phone dialer, the file-sharing menu, the photo library, the e-reader, and the search gesture. Each feature replaces a task users were previously handling manually — verifying caller identity by instinct, transferring files through cloud services, trying on outfit combinations, re-reading chapters to place themselves, and searching item by item.

The RCS handshake approach carries the clearest signal about Google's platform strategy. By building fake call detection on an open standard that other developers can adopt, Google is positioning the Android ecosystem — not any individual app — as the verification layer for voice communications. Whether that positioning holds depends on how quickly third-party dialers and OEMs adopt the RCS handshake model, and how quickly scammers adapt to methods that do not require spoofing a number already in the contact list.

Android 17, which Google teased alongside the June drop, is expected to deliver further updates before the end of June 2026.

Frequently Asked Questions

How does Android fake call detection work?

Android's fake call detection uses an end-to-end encrypted RCS cryptographic handshake, not audio analysis. When a contact calls, their Phone by Google app sends a silent verification token over the RCS network to the recipient's device. If the token is absent — because the call is being routed through VoIP spoofing software — the recipient's phone pings the contact's real device. If that device confirms no call is in progress, a warning appears on screen. Both parties must be running Phone by Google on Android 12 or later, with RCS active.

Which Android phones are getting the June 2026 update?

Pixel devices began receiving the June 2026 Android Feature Drop on June 2, 2026. Samsung Galaxy S24 and S25 series, Galaxy Z Flip6, Z Flip7, Z Fold6, and Z Fold7 devices began receiving it on June 15, 2026. Additional OEM devices — including OnePlus 15, Xiaomi 17T Pro, Vivo X300 and X300 Pro, and Honor Magic V6 — are receiving the Quick Share AirDrop features. A broader rollout across Android 12 and later devices is continuing through June and July 2026.

Does fake call detection protect against all scam calls?

No. Fake call detection only works when both the caller and recipient are running Phone by Google as their default dialer, with Google Contacts, Google Messages, and an active RCS connection on both ends. It does not protect against calls from contacts who use a different dialer, who have RCS disabled, or who call from an iPhone. It is specifically designed for contact-impersonation attacks — calls that spoof a number already in the recipient's contacts — not for calls from unknown numbers.

What is the Google Photos Wardrobe feature?

The Wardrobe feature in Google Photos uses Gemini to analyze clothing items already saved in a user's photo library and generate outfit combination suggestions. Users do not need to photograph their wardrobe specifically for the feature — it draws from photos already in the library. Rollout began mid-June 2026 and may take several weeks to reach all eligible devices.
