Mark underneath the glass

[Msteer]

I recently purchased an iPhone 6 (end of March) and a few days ago I noticed what appears to be a grease mark underneath the front glass of the iPhone 6. Now the mark isn't on the screen and can only be seen when the light hits it right, so it isn't too much of a concern. However, now I have seen it I can't unseen it... The only real major worry I have is that if I was to sell the phone in the future, the buyer may be unhappy...

I have tried taking a photo but can't get a camera to focus properly on it.

What would you do in this situation?

Make a Genius bar appointment.

Thanks for your help, I've scheduled a phone call from Apple to discuss it.

Uploaded some pics now, any ideas? - Bottom left of phone.

That's a pretty big mark. I would get it swapped out.

Going to take it into apple next week. Are they more likely to swap it or repair do you think?

They probably will swap out the front of your phone.

Which believe it or not can actually lead to more problems, I hope everything goes smoothly for him. I had the front of my imac's screen replaced recently and theres a bit of backlight bleed now in the corners where previously there wasn't any.
