Got my black iPhone 5 a few weeks back ... all was perfect, except for a speck of something under the screen. I was 50/50 with regards to just keeping it, but I ended up getting it replaced as I wanted my £699 phone to be perfect. The replacement arrived with either a scratch on the LCD, or a row of dead pixels. I'm now on my second replacement (3rd phone) and went for a white one this time, to see if switching colours would bring me a bit of luck. NOPE! It has very bright dead pixels, slap bang in the centre of the screen which simply GLOW on a black background! I SO wish I'd have kept the first iPhone with the speck under the screen. My eyes are razor sharp and it was hard, if not difficult for me to ignore it all of the time but with hindsight I would have just lived with it and got on with enjoying the phone. I am now left with another "dud" phone, boxed up and waiting to be collected for return ... then another wait for a replacement to arrive. The moral of the story ... I have come to accept that it is near to impossible to buy an Apple product and have it arrive with zero defects. I picked up my 64gb iPad 4th gen with cellular on Friday, and that too has a speck under the screen, but I am going to just keep it. I am sick of the "exchange game". I am returning this iPhone as dead pixels can worsen. However, if the replacement arrives with a speck under the screen but no dead pixels, then I will keep it and just get on with using and enjoying it. It is such a shame that I have had to come to this conclusion with a brand that charges a big premium for their products, but the moral of the story is ... that's just the way it is!
