It finally happened: With a few quick swipes and taps, our mobile devices become conduits of live two-way video through which we can speak face-to-face with family members, significant others, friends, colleagues, and acquaintances. Video chat is no longer science fiction and can be part of our daily communications. However, it seems that only a relative few are actually using this game-changing technology,
   According to a study from last fall, about  68 percent  of all American adults own a smartphone, which is roughly two in three American adults. Of those people, less than half (  47 percent  ) have ever used video chat platforms on their smartphones, and this represents a sharp increase from 33 percent in 2013 and  19 percent  in 2011. Obviously, there are more and more people using video chat on their smartphones. On the other hand, with several capable video chat platforms from which to choose, why are only a minority of smartphone users using them?
  One reason could be that it can sometimes be difficult to have off-the-cuff video chats in the same way we make phone calls. It’s one thing to jump out of the shower to take an important phone call and another matter to video chat with someone while wearing only a towel. Video chat requires more foresight and preparation than is necessary for phone calls. Or perhaps you’re of the opinion that video chat seems more complicated than it’s worth. If that’s the case, fear not. We have you covered.
   If the release ofGoogle Duo tells us anything, it’s that video chat is as relevant as ever and will likely hold a prominent place in mobile communication as we move forward. Whether you’re simply a late adopter or haven’t gotten around to learning how the whole “video chat thing” works, the following is a concise guide to the art of the video chat using four of the most popular and easy-to-use platforms: Google Duo, Google Hangouts, Skype, and Facebook Messenger.
   Google Duo

   It’s no surprise that some of the best video chat platforms for Android users are the ones that were actually made by Google, with the first in our guide being Duo. Google Duo is the latest video chat platform for Android and Google seems to be banking on it becoming the Android equivalent of Apple’s FaceTime for iOS. However, the key difference (and what should be a major advantage, but that’s another story) between Duo and FaceTime is that the former supports both Android and iOS. This means if your friends download Duo, you’ll be able to video chat with all of them no matter who carries an iPhone and who carries an Android. (Apologies to the dozen or so Windows Phone users out there who are feeling left out.)
   How to start using Google Duo for video chat

  
       
  • Setup your Google Duo account:  First, download the Google Dup app from the Play Store and complete the painless setup process. It will ask for your cell number so it can send a verification code via text, which allows Duo to link your cell number to your Google Duo account. The app recognizes anyone who’s signed up for Duo using phone numbers stored in a device’s contacts list. By verifying and linking your cell number to your account, your friends will be able to see that you’re available for Duo video chats.   
  • Open Duo and begin initiating a video chat: When you open Duo, you’ll notice the app immediately activates your front-facing camera, showing you a live image of yourself with a “Video call” button underneath. Click that button.   
  • Choose someone for a video chat: At this point, you will see an in-app list of your contacts. Any contacts who are already using Duo will appear at the very top of the list, followed by the remainder of your contacts, each with their own “invite” button so you can invite them to use Duo. Begin your video chat by clicking on the name of the Duo user of your choice. Duo will begin to call that person in much the same way as a regular phone call. As long as your recipient has a WiFi or LTE connection, he or she will be prompted to answer or decline your “video call”.  
  Something else that should be mentioned here is a feature called “Knock Knock”. Instead of seeing the photo that’s associated with your contact information, Knock Knock lets the person whom you are calling actually see you via your front-facing camera before he or she answers the call. It’s a bit of an odd feature that has brought up issues concerning privacy, but you have the option to turn off Knock Knock in the settings. If you have Knock Knock turned on, make sure you’re actually ready for your video chat before you begin initiating the connection.
   Google Hangouts

A beginner’s guide to video chat-2 (the,beginner,s,guide,beginner,s,guide,beginner,akb48,beginner,phonics,for,beginner)

  For those of us who prefer the simple, unadulterated predictability of Google services, Hangouts is typically the preferred means of conducting video chats. Granted, many of us will go off and explore new services and platforms on occasion, but we routinely return to Hangouts because it’s simple and reliable. If Duo is the new kid on the block who’s trying to make friends, Hangouts is that dude who comes home from college to throw great parties throughout the summers and during the holidays.
   Unlike Duo, Hangouts isn’t just for video chat. When it was  unveiled in mid-2013  , Google Hangouts — which took its name from the popular Hangouts video chat feature of Google+ — was multifunctional, proprietary communications platform for instant messaging, voice calls, and video chat. In short order, SMS integration was added to Hangouts, but more recently was ported off Hangouts and into its own separate application called Messages. Today, there seems to be a dichotomy among Hangouts users: people who use Hangouts for instant messaging (typically a business scenario) and people who use Hangouts for video chat.
   Getting started with video chat on Google Hangouts

  
       
  • Sign up for Hangouts  : Chances are you’ve already signed up for Hangouts and used it for one reason or another. It doesn’t require a cell phone number and comes pre-installed on virtually all Android phones, so all it takes to start using it is to be signed into your Google account.   
  • Begin initiating a video chat:  Open Hangouts and click the “+” button in the bottom-right corner. This will give you three different options: start an instant messaging session with one person, with a group of people, or to start a video chat. Choose the video chat option.   
  • Find someone for a video chat: At this point, you’ll see a list of your contacts. The people currently using Hangouts and, therefore, are ready to video chat will have quotation marks stamped on the edge of their profile pictures. As well, the words “On Hangouts” will appear next to their names. Click on the person with whom you want to video chat and Hangouts will start to call that person in much the same way as a normal phone call.  
   Skype
