The new Google video-calling app Duo- How to get started with Android

Duo App

Google Duo App for Android

Google’s recently launched video calling app, Duo, which has now hit over 10 million downloads on Google Play. The Duo app is available in all countries where Google Play is available and can be downloaded free. The Duo app lets people call their phone contacts as long as they have the app installed and one of the biggest highlight features is it can work even on low networks. Another notable feature of the Duo app is ‘Knock Knock,’ which essentially shows preview video of the caller and lets people decide whether to answer or not. Google had previously confirmed that the Duo video calling app uses end-to-end encryption and will be HD quality though the app will adjust it as per the available network.

How to get started with Duo App

Duo App- Getting Started

Getting Started with Duo App

To get started with Duo, all you need is a phone number. Obviously your android cell phone is not without a phone number. You don’t need to create a separate account, nor do you need a Google account. Duo doesn’t use your Google account in any way.
The first time you launch Duo, you’re asked to enter your number. Google then sends you a text message containing a code to enter.
Once you’ve verified your number, you’re signed up and ready to start using Duo.
If you decide Duo isn’t for you after trying it, you should remove your number from the service before deleting the app. To do that, tap on the menu icon > Settings > Unregister phone number. A few seconds later, Duo will display an alert letting you know your number is no longer tied to the service and then you’re free to act like Duo never happened.

Features of Duo App

Simple Interface

The calling experience is as absolutely simple as possible with this app. That’s why it is phone-number based, there is no need for a new account, and the user interface is very straightforward.
The UI is the person you’re talking to. It takes one tap to get into a call, one tap to answer, and, in general, everything is focused on getting you into a call as quickly as possible. Also if you navigate away from a call, the video will stop. In short, if you can’t see yourself, the person you’re calling also can’t see you.

High quality video

To keep you connected, Duo adjusts call quality based on changing network conditions. That means when bandwidth is limited, Duo will reduce the video resolution to keep the call going smoothly. In fact, you can manually turn this on: A “limit mobile data usage” option can be toggled to restrict data usage on cellular networks, lowering video resolution but consuming less data. When the network quality gets really poor, Duo will fall back to just audio.
Also Duo tries to switch between Wi-Fi and cellular data automatically without dropping your call. This means you can be on a call at home or in the office, and it should stay connected even if you leave and step out of Wi-Fi range.

Duo App

The app doesn’t have two connections going on simultaneously, but it simply monitors to see if a better connection is available. Duo always prefers Wi-Fi, assuming the connection is strong enough. The app will switch to cellular if Wi-Fi degrades or gets out of range. Duo will, however, switch back to Wi-Fi if it deems the connection strong enough again. Calls can still drop, of course if Wi-Fi deteriorates and cellular isn’t available, your call will disconnect.

Knock Knock

The real differentiating feature for Duo is called Knock Knock. In short, you see a live video of your caller before you pick up. Knock Knock only works for people in your contacts  you don’t want everyone who can get your number calling you with a video preview.

Knock Knock reduces the barrier to starting a call. It gives you a sense of what the person is up to and why they want to chat. It’s thus much easier to start off a call with a positive emotion rather than with the “Why are you calling me?” reaction many of us experience when getting a call out of the blue.

On Android, Knock Knock works on your lock screen, while on iPhone you have to be in the app to see the video preview. This is because Android provides an API for apps to take over the lockscreen. Apple doesn’t offer such an option to app developers, so iOS users will simply get a notification on their lockscreen. If you press preview, Duo will take you into Knock Knock. So you can see the caller before you pick up with Duo’s live preview feature.

More features from Duo

All Duo calls are end-to-end encrypted by default. Because the calls are set up via Google’s servers and rely on peer-to-peer technology, encryption is a must to ensure none of the intermediate networks can tap into your call.

Duo leverages WebRTC, an open-source project for browser-based real-time communication that was also developed by Google. The two teams at Google worked closely together, so improvements have been built back into the platform. While building Duo, the team worked on bandwidth estimation, to increase and decrease the video quality, and on making sure audio echo is minimized. A lot of that work went back into WebRTC, improving the project for other apps and services that rely on it.

Duo also relies on Google’s network protocol Quick UDP Internet Connections (QUIC). From a network technology level, QUIC helps reduce latency and gets the call set up faster by allowing Google’s servers to establish an encrypted connection and deliver the call to your device in a single round trip.

The latest about Duo App

Duo is replacing Hangouts for video calling on Android and will therefore in effect become the new default app for video calling on Android.

Though Google itself has said it intends to continue to develop it and target it at business customers  but in the future if you buy an Android handset you’ll have to go through the extra step of downloading and installing it. The smartphone makers can still opt to include it, although that’s unlikely considering that many of them have their own messaging platforms to push.

The WhatsApp-style messaging app Allo, however, launched alongside Duo earlier this year, isn’t being included in the core package of apps – apparently Google thinks video calling is more of a priority at the moment. The changes come into effect at the start of December so all of the shiny Android phones launched in 2017 will come with Duo on board.

To download Duo App at Google plays store for your android you need 4.1 and up version of your cell phone device to run smooth. All of the above features makes Duo great video calling app.
