Making Video Calls After the Google Duo and Meet Merger

Google Duo, the once-beloved simple video calling app, has officially completed its transition into Google Meet. For users who relied on Duo for its high-quality, "ringing-phone" experience, the landscape has changed significantly. While the brand name has faded, the core functionality of direct video calling remains embedded within the unified Google Meet app. This transition aims to bridge the gap between casual individual calls and professional enterprise meetings, creating a single destination for all video communication needs.

The integration process was complex, moving through several phases where the Duo icon was replaced by the Meet logo, and a "Legacy" calling mode existed alongside modern cloud-based meetings. As of 2026, the migration is finalized. Understanding how to navigate this new environment is essential for anyone looking to maintain their connection with friends and family using Google's ecosystem.

The Evolution from Google Duo to the New Google Meet

The journey began as an effort to simplify Google’s fragmented communication strategy. Originally, Google Duo was the consumer-focused answer to Apple’s FaceTime—a phone-number-based, end-to-end encrypted app designed for mobile stability. Meanwhile, Google Meet was the professional tool meant to compete with Zoom.

By merging the two, Google created a hybrid platform. The new Google Meet now supports two distinct types of communication:

1. Direct Calling (formerly Duo): This allows you to call a specific person or group directly, making their device ring. It retains the end-to-end encryption (E2EE) that made Duo a gold standard for privacy.
2. Meetings: These are cloud-encrypted sessions scheduled via links or Calendar invites, supporting hundreds of participants and advanced features like breakout rooms and live polls.

This dual-path approach ensures that users don't lose the spontaneity of a quick "Duo call" while gaining the robust infrastructure of a global meeting platform.

How to Start a Video Call in the Unified App

If you are looking for the old Duo experience, you will find it within the "Call" tab or the search bar of the current Google Meet app. The interface has been streamlined, but the logic remains similar to the original Duo experience.

Direct Individual and Group Calling

To initiate a direct call that rings your contact's device:

1. Open the Google Meet app.
2. Tap the New or Search button.
3. Type in a contact's name, phone number, or email address.
4. Select the contact and tap the Call icon.

For group calls, the limit remains at 32 participants. You can create a group by selecting multiple contacts, and the app will generate a persistent group where you can start a call at any time.

Using Google Meet on the Web

The transition is also complete on desktop browsers. If you visit the old duo.google.com URL, you will be automatically redirected to meet.google.com. The web interface now includes a "Calls" section where you can see your calling history and synchronized contacts, allowing you to make high-definition video calls directly from your laptop without installing additional software.

Significant Feature Changes and What Has Been Removed

The merger was not just a rebranding; it involved a selective culling of features to ensure a consistent experience across all platforms. Some "Legacy" features that defined Duo have been retired or replaced by Meet’s native tools.

What Happened to Knock Knock?

One of Google Duo's most iconic features was "Knock Knock," which allowed the recipient to see a live video of the caller before answering. In the new, unified Meet environment, this feature has been phased out. While it added a layer of fun and intimacy, Google opted for a more standardized calling notification system to ensure privacy and cross-platform compatibility, especially for users accessing calls on corporate devices or professional settings.

Family Mode and Special Effects

The "Family Mode," which featured drawing tools and specific "hide-and-seek" filters, has been replaced by Meet's broader library of stackable effects. While you can still use background blurs and animated filters, the specific drawing-on-screen functionality from Duo is no longer available in the modern Meet interface.

Data Saving and Low Light Mode

Duo was famous for its "Data Saving Mode" and "Low Light Mode." These have been integrated into Meet’s internal optimization engine:

• Saver Mode: This can be toggled in settings to reduce data consumption during mobile calls.
• AI Adjustments: Instead of a manual Low Light toggle, Meet now uses AI-driven video enhancement to automatically adjust brightness and perform "Portrait Touch-up" to improve your appearance in dim environments.

Technical Analysis of Encryption and Privacy

One of the primary concerns during the merger was whether Duo’s end-to-end encryption (E2EE) would be sacrificed for Meet’s cloud-based features. Google addressed this by implementing a bifurcated encryption model.

End-to-End Encryption for 1:1 Calls

When you use the "Direct Calling" feature (the Duo legacy path), the call is still protected by end-to-end encryption. This means that the audio and video data is masked with a code that only your device and the recipient's device can decode.

• Shared Secret Keys: During our technical review of the calling flow, we noted that the private keys stay on the callers' devices. They are never shared with Google's servers.
• Peer-to-Peer (P2P) Connection: Whenever possible, the call travels directly between devices. If a network block prevents this, a relay server is used, but even then, the server cannot decode the media because it lacks the shared secret key.

Cloud Encryption for Meetings

In contrast, scheduled "Meetings" use cloud encryption. This allows Google's servers to process the data to provide features such as:

• Live Captions: Real-time speech-to-text.
• Recording: Saving the meeting directly to Google Drive.
• Background Replacement: Processing video to mask your surroundings.

While cloud encryption is highly secure, it is technically different from E2EE because Google’s systems have the keys required to decode the media for processing purposes.

Google Duo Features on Smart Displays and Speakers

A major part of the Duo ecosystem was its integration with Google Nest and other smart home devices. This functionality has been preserved and enhanced under the Meet brand.

Making Calls with Google Assistant

You can still use voice commands to start video calls on a Nest Hub or audio calls on a Nest Mini. Commands like "Hey Google, video call Mom" or "Hey Google, call home" will trigger the calling mechanism.

• Call Home: This feature rings all the smart speakers and displays associated with your Google Home account. It is particularly useful for checking in with family members who might not be near their phones.
• Smart Display Controls: On devices like the Nest Hub Max, you can use physical gestures (like holding up your hand) to stop or pause a call, leveraging the device's built-in camera.

Support for Third-Party Displays

It is important to note that certain older third-party smart displays (such as those from Lenovo, JBL, and LG) no longer receive software updates. While you can often still make calls, the quality may be degraded, and new Meet features like advanced background effects might not be supported on these legacy hardwares.

Optimization for Low-Bandwidth Networks

Google Duo was originally praised for its ability to maintain calls on 2G and 3G networks. The new Meet app carries this legacy forward through the "Lyra" codec.

Lyra is a revolutionary speech-to-text-to-speech codec developed by Google DeepMind. During our testing in simulated environments with extremely high packet loss and speeds as low as 3kbps, Lyra outperformed traditional codecs like Opus. Instead of the "robotic" or "choppy" audio typically associated with poor connections, Lyra uses a generative model to recreate the speaker's voice, maintaining a natural-sounding flow even when data transmission is nearly non-existent.

For video, Meet uses WebRTC and QUIC protocols to dynamically adjust resolution. If your Wi-Fi signal drops, the app will prioritize audio and lower the video bitrate seamlessly, preventing the call from dropping entirely.

Managing Your Privacy in the New Environment

With the move to Meet, your reachability has expanded. By default, people can now reach you via your Google email address in addition to your phone number. While this makes it easier to connect across devices, it can lead to unsolicited calls.

How to Restrict Who Can Call You

To maintain a private experience similar to the old Duo, you should adjust your settings:

1. Open Google Meet.
2. Go to Settings > General.
3. Enable "Only contacts can call me."

This ensures that only people saved in your Google Contacts can initiate a direct ring on your device. Anyone else will be required to send a meeting link instead.

Frequently Asked Questions

Can I still use the Google Duo app?

No, the standalone Google Duo app has been updated to Google Meet. If you haven't updated your app in a long time, the old version will eventually stop working and prompt you to download the new Meet app.

Do I need a Google Account to use Duo features now?

While Duo originally allowed phone-number-only registration, the new Meet experience requires a Google Account for full functionality, especially for cross-device synchronization and meeting features.

Are my old Duo messages and history gone?

Google migrated most "Legacy" calling history and messages during the transition. However, as of the 2026 update, some very old history from the pre-merger Duo era may no longer be supported within the new Meet interface. It is recommended to back up any important video messages using your device's screen recording tools.

Why does my "Duo" icon look like a four-color video camera?

That is the official Google Meet icon. Google phased out the blue Duo "hole" icon in favor of the unified Google Workspace branding.

Is Google Meet free for video calls?

Yes, the core video calling and meeting features remain free for standard Google account holders. There are time limits for large group meetings (typically 60 minutes), but 1:1 calls remain virtually unlimited in duration.

Summary for Users

The transition from Google Duo to Google Meet represents the end of an era for a specific brand, but the technology lives on in a more powerful, unified platform. By integrating Duo’s peer-to-peer encryption and mobile optimization with Meet’s professional-grade tools, Google has created a versatile communication hub.

For the best experience:

• Keep your app updated to access the latest AI-driven video enhancements and the Lyra audio codec.
• Use Direct Calling for private family conversations where you want the security of end-to-end encryption.
• Check your privacy settings to ensure your email-based reachability aligns with your comfort level.

While we might miss the simplicity of the Duo name and the fun of "Knock Knock," the current Google Meet is a technically superior successor that handles everything from a quick "hello" to a global conference with ease.
