Hi guys. I'm new to the forum so go lightly on me I went into the apple store yesterday as I had a Genius Bar appointment. Basically my old model had an issue with the lock button and the guy in their swapped it for a nice shiny new model. Onto the new issue. The replacement handset seems to have an issue with the pixels and clarity of the colours on my device. Everytime I look at something light such as a web page, certain parts of it are streaky. So for example if there are boxes in the screen they're streaked outwards and it's really irritating. Second issue is the screen seems to be really faint with certain colours and I'm not benefiting from the Retina display. Now the chap in the store told me to leave it for a month and go back if continues. He said this as he reckons its newly manufacture and it's just the manufacturing process settling in. I'm happy to do this, however it's so irritating I wanted to see if anyone has had any problems like this yourselves? If so what advice can you give me. Kind regards, Kieran.
