Is an IPhone XS Max supposed to have red eye in the photos using flash?

I noticed with my IPhone XS Max that when I take photos using the flash option that I get red eye in the photos where th pupils glow red. I have had 3 replaced phones from Apple which all seemed to be doing this. My 6s plus sometimes done it but very minor. Is this normal or is there a fault with the IPhone XS Max?
I did backup from my 6s plus so I'm not sure if it's either a back up problem or a technical fault problem.
What do you think it is?

Added (1). The red eye doesn't work
Also will resetting settings also help with this?

It's not a technical problem. If you click edit on the picture they have an option to where you can get rid of the red eye.

It is because of two things, An iPhone is a phone, not a camera and iPhones are overpriced junk.

Ask Apple.

Yes, this is absolutely normal for any camera (including the $15 one in your iPhone). The red eye is caused by the LED (not actually a flash) being located too close to the lens. What happens is that the light from the LED bounces off of the back of the eye and then right into the lens. The angle has to be just right in order for this problem to occur. Your only option is to use an external flash (if one exists), buy a real camera, or use the phone with the flash turned off. Of course you can also remove the red eye with various apps, too.

To see how this works in real life, hold a flash light while looking into a mirror. The angle from which the light comes from the flashlight equals the angle from which the light reflects off of the mirror. If you get the angle just right, you can shine the light right into your own eyes. Move the flashlight up/down/left or right just a little bit, and the angle will be off enough so that the light misses your eyes. This is what you need to do with any camera in order to prevent red eyes.

Red eye caused by flash too close to the lens. Professional photographers use a hand-held flash that can be spaced some distance from the camera lens. Some cameras pre-flash to cause the human eye pupil to become tiny (contract). Subject looking away from the camera can mitigate.

It's not the phone. It's you. Get yourself replaced.

Haha!

The flash is too close to the lens. You can't change that. If the phone has an option for anti-red eye then enable that. A better solution would be to shoot under better lighting conditions where you don't need to use flash.
