Google Duo on Xiaomi: What is it and how to use it

Google Duo is a video calling app from Google that is often pre-installed on Xiaomi smartphones, and many users notice it on their list of apps, but not everyone understands why it works, and if you see a phone icon on a green background and you wonder, "What is it?", this article will help you understand.

Unlike standard calls, Duo specializes in high-quality video communication, even in weak Internet. The application is integrated into the Google ecosystem and is closely related to services like Google Contacts or Android Messages. On Xiaomi, it can appear both by default (on some models) and after updating the MIUI firmware. Next, we will explain in detail how to use it, how it differs from competitors like Zoom or WhatsApp, and whether it should be removed.

What is Google Duo and why is it Xiaomi?

Google Duo is a cross-platform video and audio calling app designed as an alternative to Skype, FaceTime (from Apple), and other services.

• 🎥 Video quality: adapts to the speed of the Internet, supports 720p and 1080p.
• 🔒 Encryption: All calls are protected by end-to-end encryption (like Signal).
• 🤳 Knock Knock: Shows live video of the subscriber before answering the call.
• 📱 Integration with MIUI: Xiaomi replaces the standard video call app.

Xiaomi Duo can appear on smartphones for two reasons:

1. Pre-installation in MIUI firmware (especially on models for the global market, for example, Redmi Note 10 or POCO X3 Pro).
2. Automatic installation via Google Play Services as part of the Google Mobile Services (GMS) package.

Important: Duo is not a system app (unlike Mi Video Call on some Xiaomi), so it can be removed without harming your phone, but if you’re actively using other Google services (like Gmail or Photos), it can be useful for fast video calls.

• 📶 Adaptive bitrate: automatically reduces video quality when the signal is weak (useful for Redmi with a low signal). 4G).
• 🎤 Noise suppression: filters out extraneous sounds during a call.
• 🖥️ Duel camera support: Xiaomi with dual frontal (e.g. Mi 11 Ultra) can switch between cameras while calling.

The Internet connection (Wi-Fi or mobile data) is used for calls, but if the subscriber does not have Duo, the system will offer to send him an invitation via SMS. There is also a Duo for the Web feature that allows you to call from your computer via the Chrome browser.
