If you are from the previous generation, then you remember the days when you couldn't send photos with high resolution and it took a long time to reach the destination. Thanks to today's advanced technologies, including state-of-the-art mobile equipment and protocols, this has quickly become a thing of the past. Nowadays, devices like smartphones, tablets and computers can send files, almost instantaneously, very large as high-resolution images and even videos.

Years ago, Google introduced the Duo product, which has all the qualities to be one of the leading products in the field of video calls, because if it is seen in perspective, it can be integrated into a variety of devices, in addition to being safe with a encrypted connection. The application has been improved several times in recent years and with it you can easily make calls from various devices, such as a smartphone, tablet, desktop or laptop.

To enjoy it, you only need to download it from the Google or Apple online store, you must also have an active mobile device that can receive SMS messages and a mobile phone number. Once you download it to your phone, whether you use the Android or iPhone operating system, it will open automatically. You need to confirm your phone number and the app will automatically search for people who also use it on your friends lists. There is no option to add email, so you have no alternative but this one. The application will actually send an SMS to your phone which will recognize the received confirmation code and simply be ready to use it.

Once the main page loads, you can see in the active area your contacts who are already using the application and, respectively, if you scroll down, you will see those who are not using the application so that you can send them an invitation.

After you have completed these simple settings, you can test the app and evaluate how it works on your device. It is better to try the group chat room where you can meet up to 8 people. That same 7 of your friends including you! To initiate such an action, swipe up on your screen to see your most recent contacts who have used the application on the access point. Click the "Create group" button. Then you can search for your friends using their names or mobile phone numbers in the search box. As administrator of this group, you can configure and name or mute any of the participants if you need silence, you speak and they have to listen to you. Basically anything that can be done in a simple phone-to-phone chat. If you click the YouTube button for live chat, you will see the people who join in blue, so if someone cannot participate for technical reasons, they will also introduce themselves.

If you want to improve your performance in front of the camera, remember that this is the correct placement of your phone. This can even be a makeshift tripod if you want, but it's at your head level. The other important choice you must make is where to go for proper lighting. Any natural light that doesn't trap you too much, such as against a window when the sun is shining directly on your face, can greatly improve your camera speaking skills.

The main advantage of these new technologies is that, in addition to convenience, they also offer completely new horizons for your commitments; For example, if you are a teacher you want to teach your lessons and the lack of a classroom will not prevent you from developing in this direction, just think about it. You don't have to worry about sound quality, because the Duo will use the sounds from the built-in microphones on your mobile device, tablet, or computer.

Google Duo will indicate that there is an active chat to each of the guests if you decide to join from another device. In fact, as long as you keep the chat active, communication can take place in it. You can use your different cameras and send a variety of messages like short videos or just text and audio. You can also download various materials from your conversations, which will be active for 24 hours.
