The app, which began as a simple social media photo sharing platform, has been expanded to include much more. Between live videos, stories, chat and animated stickers, Instagram is more than the sum of its images. Now there is a new feature that can be added to this list for Android and iOS – video and audio calls.
We knew this feature was on the way well before it officially came out. An image of a video chat icon launched the curiosity in January 2018, and a few months later, video and audio call options were found hiding the Android app APK file, which further enhanced the rumor. The video chat became official on June 26, 201
Opening a Direct Message Thread
To start a video chat, you must open or start a direct message thread with another user. To find your direct messages, tap the aircraft icon in the upper-right corner of the Home screen. To start a new direct message with someone, tap the + icon or tap the ellipsis (•••) icon on the user's profile page, and then choose Send Message.
Starting a video chat with this person  In a direct message that could contain only one person or a group chat of up to four users, tap the top right of the video camera icon instead of the normal camera icon They record vanishing photos and videos. When you tap on it, a video call is automatically started in the thread. You may need to give Instagram permission to use your camera and microphone if you have not already done so.
You can use any user on Instagram Start video chat as long as they have not blocked you. If they've muted you, they probably do not know they're joining the call.
Accepting or joining a video call
The other user or users have the appropriate notification settings enabled, and the device should display an incoming call screen You can go directly to video chat or swipe down to decline. Instead of a full-screen notification, you might see a simple banner notification with the Reject and Join options instead.
If you're already in the direct message thread, your video camera icon will appear blue around it with an animated bubble. You could tap that to join, or click on the message below that says "Tap to join."
If you do not answer the call, you will be greeted by a "No Join" screen. You can choose whether to cancel the call or try the call again.
When a call is successful, Instagram splits your ad into two, three, or four – one square for your camera, one for each of you friends
If you're familiar with other video calling programs such as FaceTime are, you are exactly right here. You can tap the arrows at the top right of the screen to switch between cameras. If you tap the square in the upper-left corner, the chat window is minimized and you can browse Instagram while you continue the video call. When you tap the shrunken video chat window, it returns to full screen mode.
If you do not want to show your face, you can tap the bottom of the camera key to turn off the video feed for audio-only chat. They can do this before someone joins the call, and they can return the favor by disabling their camera feed after joining. Tapping the microphone button mutes the sound.
To stop the chat, just tap the red phone icon below, just like a similar phone or video call. If there are two or more users left in the video chat, the call ends for you only and the call will continue.
