I powered up my brand new iPhone 5 today (Black 32 GB, AT&T) and noticed the screen, which is supposed to be the nicest in the industry, had an ugly yellow cast to it. At first I thought I might be imagining things. After all, maybe this was just the new color saturation I'd read about. But then I compared it to my wife's new iPhone 5. Her screen looked beautiful and crisp. Mine looked as if it had spent the past two years mopping floors in a busy cigar bar. (I exaggerate, but it was still pretty grim.) I returned the phone to Best Buy where I got it, and fortunately they had a replacement in stock. However, upon boot-up the screen showed the same ugly yellow as the first. I sheepishly returned it and went home with my funky old iPhone 4 that I've had for more than two years. It may not have Siri, but its screen doesn't remind me of death by second hand smoke. I don't know if this defect is bad enough to bother most people. I'm a designer by trade, so I understand I'm a little more sensitive to these color issues than 97% of the population. The Best Buy staff compared it to other iPhones they had on hand and noticed the yellow-ish look. But to them it wasn't a flaw, just a difference in production. I know previous iPhone releases have had batches of screens that leaned hard toward dingy yellows. Has anyone else noticed this with the iPhone 5?
