How do you video chat on a phone?
Open the site or app you are using, start the call, and allow the camera and microphone when your phone asks. Hold the phone at eye level, about an arm's length away, with a light source in front of you rather than behind. That is genuinely all a first call needs.
On an iPhone, Safari asks for camera and microphone access the first time a page wants them. If you tapped "Don't Allow" by accident, open Settings, scroll to Safari, and set Camera and Microphone to Ask or Allow. On Android, Chrome shows a similar prompt; if you blocked it, tap the icon to the left of the address, open Permissions, and switch both back on.
Prop the phone against something stable if you can. A phone held in your hand drifts, and the person on the other end ends up looking at your ceiling.
