Screen mirror

When you take a picture with any camera it shows how you would look to someone looking at you. The front camera does the same thing; the photo shows what someone looking at you would see. When you look into the camera before you take the photo it reverses your real image so you won’t be confused when positioning it. But the actual picture is correctly oriented.

How would the A look to someone looking at you (NOT how it would look to you if you looked in a mirror). Put the pendant on someone else and look at it.

There is no setting to change. The camera shows what you would look like to someone looking at you, which is the reverse of how you look to yourself when you look in a mirror.

Screen mirroring requires Apple TV.

And what is “camera mirror?"

It isn’t mirror mode. Take a photo of a magazine with the front camera. Is the text in that photo correct?
