iPhoneX selfie portrait
I'm trying to take a selfie portrait.
Before I took the picture, I could see that my face is clear and the background is blur. Exactly how I wanted it to be. But after I took the picture, and I look at it, the effect of Portrait is actually not there. The background remains clear and "in focus".
I use the normal button on the front of the screen to take the picture.
Occasionally, I do get the Portrait effect I want; but not always and that is annoying. I do not have warning messages like the background lighting is too bright or telling me to move further away etc.
So what I have done wrong?
iPhone X, iOS 11.2.1
