Why is that my camera does not autofocus on things only if i touch it on the screen? The photo is obscure, not sharp if I don't focus manually on something, even if I turn on the pre-AF.
I attach 2 photos, the difference is if I touch the screen to focus on something.

I did it twice already, it doesn't work.

The issue seems to appear less often when I am taking pictures in an outside area.

It seems to appear way more frequently at short distances (1, 2 meters), or in indoors area (a few meters).

It .. seems focus itself is changing, so the af-motor at least is working , somehow.

1.
Can you focus on a wall, say 2-3m away.
Then put your hands in front of the camera - 30cm away from the camera .
And using the main camera (as your video).


2. What about "touch to focus". Can you try that too?
