Instagram is a great social media platform for sharing photos and videos. However, some people may find it difficult to use Instagram when they want to make video calls. This is because the app does not allow you to make video calls without first disabling the phone’s microphone. To do this, you need to go to the Instagram app and select the three lines in the top left corner of the screen. Then, select “Settings.” On the Settings page, you will need to click on " Calls." On the next page, you will need to select “Disable microphone.” After doing this, your phone will no longer be able to make video calls.
