Q: i phone 6  does not focus on camera use to ?

Hi johntubs,

If you are having an issue with poor image quality, such as from bad focus, on your iPhone's camera, I would suggest that you troubleshoot using the steps in this article - 

Get help with the camera on your iPhone, iPad, or iPod touch - Apple Support

Specifically see the section titled Your photos are blurred or out of focus.

Thanks for using Apple Support Communities.

Sincerely,

Brett L
