I just bought an XT4 to upgrade from my XT3 for the ibis and screen.
I usualy shot video with my XT3 , focus mode - multi , face-eye off (sometimes on) , speed -1 , sens +3 , and it works flawlessly .
On my xt3 always works, even in dark conditions , Camera choses to focus on the closest object or the object that fills most of the scene. And also works well with face-eye.
In my opinion face-eye should be used with "MULTI" , not area , because as soon the face is lost it will try to focus on "area box" and not the closest subject.
Here's a very very bad video i made just to show this behaviour. Both camera have latest firmware and also the lenses.

It seems like the XT4 phase detection is disabled , and only contrast autofocus works. Camera is not focusing well.
OR my xt4 is faulty ? I think there are very low chances of that.
