As soon as I opened my new iPhone 7 Plus 128GB Black I noticed that there was something UNDER the screen. It was a speck of dust or some particle that was stuck there during the manufacturing process. I knew this because I tried to wipe it off the top of the screen but it was not moving. I called apple straightaway and they said they will send a replacment (I sent the defective one back) as soon as possible. They are now taking the p*** because each apple employee is telling me different delivery dates. It says on my apple order online that it will be delivered on Monday 3rd October but the status is still 'Processing Items'!!!
It looks like there was the same problem with the iPhone 6s - https://discussions.apple.com/thread/7333065
Here is the pic of my iPhone before I sent it back:
