Either I'm having the worst luck in the world or Apple's QC has been dropped to allow them to get more iPhones out there. I'm not anal/OCD but I do expect a defect free phone for £800. I'm on my 3rd iPhone 6 Plus now: #1 Dark patch at the top of the screen (weird wavy lines). Also has yellow stain at the top left and dark shadow around the edge of the screen. The rest of the screen was a lovely cool Blue crisp white. Looked great. #2 Bright white spot at the top of the screen noticable on the Hello setup screen. So blatant I didn't even bother setting the phone up. #3 No dark patch at the top of the screen or edges. The phone spent the first 48 hours getting really hot with a pegged CPU but seems to have calmed down now. The whites on the screen are a little more yellow and there is a minor shadow across the bottom of the screen. You do have to look for it and it sometimes catches my eye when scrolling down text. Is it the perfect phone? No but the screen is the best of all three. It's very disappointing that the experience of purchasing and using an iPhone is so negative. My father has a white 6+ and it's really uniform so they do exist. I don't think its unreasonable to expect a screen with a uniform backlight and colours. Isn't that why we pay a premium for Apple products? Is anyone else going through this?
