I use an iPhone 8. By default, Skype and Zoom use the front camera. But my rear camera has higher resolution and quality, correct? How can I order video conferencing apps like Skype and Zoom to use the rear camera?
Zoom has the ability to switch cameras in the iOS app. The switch is available in the top left of the screen once you have started a meeting. It does not appear that you can select the rear camera before you start the meeting; so you will always have a moment where the front camera is "on" before you switch to the rear camera.
