If you mean the feature that keeps the screen on when you look at it, it doesn't even work outside in the daylight lolhoping a fix is coming soon!
Daylight? The sun never shines in blighty!
But, I wouldn't expect that feature to work with any current screen technology in daylight. Once they figure out how to make high pixel density color screens to look as good in daylight, as indoors, then I will expect this feature to work anywhere.
