Please try if a factory reset might help:

wipe data/factory reset in recovery (this will delete your data/settings):
- Power off and then press Power and Volume-up together for around 10 Seconds
- be sure that the little arrow point on recovery (select with volume up, enter with volume down)
- Then the open android with red triangle+"no command" is shown - press Power and Volume up together again
- Select Wipe data/factory reset with volume keys, confirm with power
- After factory reset select reboot system now

Please report if this solved your issue or not.

The procedure does not solve the problem, the camera is stil out of focus.

Are you tapping to use selective focus or leaving it to auto focus?

I have tryed both. Does not matter. Even if you tap, even if you leave it to focus by herself, the result is the same. Out of focus.

I have noticed the same. Pictures are noticably blurry. The preview looks pretty good, something happens when the picture is taken

Same problem, 20170718 update did not fix the camera focus problem.
