Alright, I have a question for people who know about cameras. I noticed underneath my rear camera lens on my brand new iPhone 6s Plus that there's a teeny tiny microscopic piece of white dust...can't even see it unless you hold the phone very close to your face and look. My questions are: 1. If the dust is closer to the parameter of the lens and not actually over the little circle in the center (excuse my lack of camera knowledge, will it even cause any issues? 2. Is there some definitive test I can do to see if my pictures will have that spec in them? 3. Would apple be able to take care of this? Thanks for the kind responses in advance.
