Hi,
If your PC has a built-in camera or a connected webcam, you can use the Camera app to take photos and videos. To help us determine the appropriate troubleshooting steps that can resolve your concern, we would like to ask the following questions:
- What is the make and model of your device?
- Are you using a separate web cam on your device? If yes, may we ask the make and model as well?
In line with the query that you have, you have the options to change what is the default view of your camera on the camera app itself. You can check this article to know more about the Camera app and webcams.
We look forward to your response.
