I have heard that Apple has adopted a "warmer" hue to the 5/5s when compared to the 4/4s (and earlier). I recently upgraded from an iPhone 4 to a 5s, and while I love it, I am having trouble getting used to the warmer tones. I notice that when both phones are in sleep mode, when put together side-by-side, the 4 has an ever-so-slight blue tint to it, while the 5s seems to have a red/maroon tint to it. To my eye, the 4 seems to resemble a more neutral hue than the 5s. Can anyone who has been in my shoes (4s [or earlier] upgraded to 5s) weigh in on this? I went to the Apple store and was essentially told "get over it" (although I was simply asking them about it) I have been using the device for about a week and I still have not really gotten used to it. Is swapping it out worth it? Or are all the 5s models this way? Thanks. I know this has been discussed before, but I still keep seeing conflicting reports.
