Hi guys, I'm sure many of you, like me, have a yellow tinted iPhone 5 screen and aren't particularly happy about it (but also can't be bothered to keep returning it as many do and end up with a duplicate of the problem). It's not that "warmer" is preferable as fanboys may say, it's simply wrong - on my phone: 106% green, 92% blue and 81% red on the RGB spectrum to be precise (measured with a lightmeter). Now, it's actually pretty easy to fix this for those that want to and as far as I've seen all the yellow tints look to be about the same level so this should be pretty generic: 1. Jailbreak. I know not everyone wants to, but this issue made me do it for the first time today and it was very stress-free. It's easy enough to Google the iOS 6 version... 2. Go to Cydia store and get the "Color Profiles" app, it's $1.99 but for me it's a small price to pay for fixing a phone I'm going to use for the next year at least, that's a lot of time looking at that screen! 3. Open the App and go to "Advanced", scroll down to "White Level" and you'll see three bars (un-named but represent Red, Green and Blue from top to bottom in that order). 4. Move the middle slider of the three to around the 85% mark, move the bottom of the three to around the 90% mark. Voila! tint fixed, a nicer, bolder and correctly coloured screen with white whites is now yours! On mine this measures perfectly, it should be around the same for all yellow-tinted screens but of course you're free to adjust as you see fit. Of course you shouldn't have to pay for this, Apple should allow this functionality since they've lost the ability to make "correct" screens in the last year or two (I imagine it's the LG supplied ones as this same tint is present on my LG plasma which I also calibrated, Samsung's are generally slightly red tinted, I've not measured a Sharp plasma) but for those that it bothers it's a small price to pay and not too much hassle. Cheers, Jim.
