Q: iphone 6 plus camera blurry

Are you using a case around the phone, if yes, remove it, and try again. If this is no the case, and to rule out a software issue, set it back to factory settings and see if the camera works after that.

If still no luck, contact Apple to get it serviced:

Same problem here. Took case off, did a full restore. Did not work. Have an appointment at Apple Store. Really hoping they can replace the camera or give me a new phone. I have taken very good care of my phone and do not want a refurb.

they maybe able to fix at apple store but unless they can just fix the camera and don't have to replace whole unit then be ready for that refurb cuz thats what probably you'll be getting unless phone is >15days old and you can just return
