Apple has acknowledged a problem with some iPhone 6 Plus cameras.
A component in the iSight camera (rear camera) may fail causing your photos to look blurry.
The iSight Camera Replacement Program for iPhone 6 Plus will allow users to replace their camera free of charge.
You’ll have to check this website to see if your iPhone 6 Plus is eligible. If you’re phone is eligible but you don’t see any image problems, don’t go rushing for a replacement. The program is valid up to 3 years from purchase.
Note that this program is for the iPhone 6 Plus only, the normal iPhone 6 isn’t experiencing this problem. [APPLE]
